Background: The metanephric glomeruli develop from the metanephric blastema and ureteric bud. The nephron anlage undergoes multiple differentiation stages, fusion and invagination that lead to the formation of nephron. Objectives: To describe the morphological changes and transformations that lead to formation of metanephric permanent glomerulus during peri-natal period. Method: The study was performed on albino rat as a model for mammalian embryonic development. Embryos of 20-22 days of gestation and neonatal litters were investigated for renal development. The specimens were double fixed, plastic embedded and semi-thin sections stained with methylene blue were examined. Results: It was shown that glomerular development continues during late pre-natal days and first week post-natally. Maturity was attended by the end of the 7th post-natal day. The developing glomerulus passes through the stages describes as vesicle, comma, S-shaped, double comma, elongation and ovale stage to become finally mature. Conclusion: The metanephric glomerulus passes through sequential, multi-stage, pleomorphic development during peri-natal period. These features should be considered during evaluation of kidney during this period.

Background: Zygote produce from once a sperm fertilizes an egg cell. Then, the zygote (unicellular) will begin chain of cellular cleavages to produce multicellular mass, its embryo, the differentiated to different tissues and organism. The development of the embryo is called embryogenesis. Coenzyme Q10, is an antioxidant produced in the body. It boosts cellular energy and may enhance the immune system. CoQ10 is present and measurable in seminal fluid, the concentration of CoQ10 directly correlates with both sperm count and motility. It is beneficial in the prevention and treatment a wide range of health problems. Objectives: The present study was aimed to investigate the possibility of using coenzyme Q10 to improvein vitro fertilization (IVF), and early embryonic development (ED) in mice as a model for human being. Methods: Superovulation program was achieved to mature healthy female mice with age 10-12 weeks and weight 24-26 gm. After sacrificing female, oocytes were collected and incubated within CO2 incubator for less than 1 hour. Sperm were collected from vas deference of males. Sperm parameters were assessed after 30 min. ofincubation. Mature oocytes were divided into three groups according to theconcentrations of CoQ10 including G1 (control group; SMART medium only), G2 (treated group; SMART medium enriched with 20 M CoQ10) and G3 (treated group; SMART medium enriched with 40 M CoQ10). IVF technique was performed for 3 groups, and assessment of IVF (%), embryonic development stage (%) and abnormal embryo morphology (%) for each embryo stage. Results: Results of the present study appeared significant increment (P<0.05) in the percentages of IVF for both treated groups as compared to the control groups. Also, significant increase (P<0.0P) in the IVF (%) was observed when using 40 M CoQ10 as compared to 20 M CoQ10. Non significant differences (P>0.05%) in the 8-cells embryo stage were assessed among control and treated groups. Conclusion: From the results of the present study it wasconcluded that the coenzyme Q10 (40µM) enriched to the culture medium improved percentage of in vitro fertilization and no effect on embryonic development.
Background: Glycyrrhiza glabra(Gg) is a herbal medicine used in the treatment of different syndromes. Recently, the effect of this plant on the reproductive system has been studied. However, its role in in vitro still not clear. Objectives: The present study aims to investigate the possibility of using Glycyrrhiza glabra extract for in vitro sperm direct activation, and its effect on in vivo fertilization rate (FR) and early embryonic development (ED) following intra-peritoneal insemination (IPI). The mice were used as an experimental model for mammals. Materials and Methods: Glycyrrhiza glabra extract (2 mg/ml culture medium) was used for in vitro direct sperm activation technique. The female mice were divided into two groups: spontaneously ovulated (SOM) and superovulated groups (SuOM). Each group was divided into two subgroups, the first: the IPI was accomplished by epididymal sperm activated in vitro by adding 20%Gg to the culture medium. The second subgroup: the IPI is accomplished without adding Gg to the culture medium. Results: In vitro activation of epididymal sperms with 20% Gg has shown positive effects on sperm concentration, sperm motility, and grade activity of progressive forward movement. There was a significant (P<0.05) increase in FR with adding 20%Gg compared with that free of Gg of spontaneously ovulated groups after 24 hours of insemination. The FR in the right oviduct showed highly significant (P<0.001) increment compared to the left. Embryonic development rate significantly ( (P<0.05) increased after 24 and 48 hours of insemination in grouping with adding Gg. The study showed that the quantity and quality of embryos generated from IPI with adding Gg were higher than that of groups inseminated without adding Gg. Conclusion: It is concluded from the results of the present study that adding the 20% Gg to the culture medium of the epididymal sperm and IPI leads to an improvement in certain sperm function parameters and supports the FR in SOM and SuOM with an increase in the embryonic development rate. These data can be utilized for artificial insemination programs.
Background: The functional and morphological development of the glomerlus is an essential part of nephrogenesis that takes place during Intra uterine life and early post-natal days. Objectives: To study the morphometric parameters of the maturation of the glomerular filtration slit of the kidney during neonatal period and its implication on the function of the kidney. Method: Rat litters are used as a mammalian model of the development during the first 8 days of post -natal life. Image analysis using Bell software system was used for morphmetric measurement of filtration silt as examined by electron microscope. Results: The width of the filtration slit of new born kidney was 11.24±1.6 nm which increased by increment to be 14.83±1.6 nm on 4th.post- natal day. Eventually reached 25.34±4.3 nm on day 8 post natally. Conclusions: In New Born litters, the glomerular filtration slit is narrower than that of mature kidney. Glomerular development continues to take place during first post natal week to reach the adult mature parameters at the end of neonatal period. This explains the low GFR found in new born mammals.
Background: Citrullus colocynthis(CC) is an herbal medicine used in the treatment of a wide range of diseases. Recently, the effect of this plant on the reproductive system has been studied.However, its role in vitro still unclear. Objective: The present study was designed to investigate the possibility of using CC extract for in vitro sperm direct activation technique, in vitro fertilization(IVF) and early embryonic development using the mice as a model for mammals. Materials and Methods: Citrullus colocynthis extract (0.05mg/ml culture medium) was used for in vitro direct sperm activation technique. The same medium was used for oocytes insemination and for culturing the embryos after 24-48 hours of insemination. The oocytes were collected from superovulated female mice and divided into two groups: first group, 343 oocytes were inseminated and cultured in CC- free Ham's F-12 medium (the control group). The second group, 345 oocytes were inseminated and cultured in 10% CC - Ham's F-12 medium (treated group). Each 4 oocytes were inseminated with the same sperm concentration (1-2 x 10^5 sperm/IVF well). The fertilization rate was recorded after 24 hours of insemination, while embryonic development rate was recorded after 24 and 48 hours of insemination. Results: In vitro activation of epididymal sperms with 10%CC has shown positive effect on sperm concentration, sperm motility, and grade activity of progressive forward movement. There was a highly significant (P<0.004) increase in FR of the treated group (61.5%) compared to control group (50.4%) after 24 hours of insemination. Embryonic developmental rate was significantly increased after 24 and 48 hours of insemination in treated group compared to control group. Conclusion: It concluded that adding the 10%CC to the culture medium of the epididymal sperm and in vitro inseminated lead to improvements in certain sperm function parameters and sustain the FR and early embryonic development rate.
Background: Many studies has been found that the pentoxifylline (PX) and L-carnitine (LC) as motility stimulants showed a positive effect on the activation of sperm in vitro and improve the forward movement after cryopreservation. Objectives: The present study aim to investigate the possibility of using the motility stimulants(i.ePX,LC and mixture of PX with LC medium) for in vitro sperm activation after cryopreservation of epididymal sperms and their effects in vitro on fertilization rate (FR) and early embryonic development (ED) following in vitro fertilization (IVF) process as a model for obstructive azoospermia in men. Methods: Fifty mature male and Fifty mature female mice, 8-12 weeks old were used. Epididymal sperms were obtained from caudal region and in vitro direct activation technique was done after cryopreservation by using four media namely; PX alone, LC alone, a mixture of PX with LC and Ham's F-12 (as control media). The four media were used for IVF of mature ova and FR with ED were recorded. Results: In vitro activation of epididymal sperms with PX, LC and mixture of PX with LC has shown positive effect on sperm concentration, sperm motility, and grade activity of progressive forward movement after cryopreservation. There was a significant (P<0.05) increase of FR in treated media compared with the control medium after 24 hours of insemination. The study showed that the quality and quantity of embryos. Conclusion: It is concluded from the results of the present study that adding PX, LC and mixture of PX with LC medium to the culture medium of cryopreserved epididymal sperms and IVF leads to an improvement in certain sperm function parameters, supports the FR and early ED rate.
Pro-fusion proteins as mitofusins-1 are required for controlling mitochondrial shape which determined by a dynamic balance between organelle fusion and fission and also supports oocyte development. When compare with somatic cell, mitochondria of oocyte are tiny and circular in presence. The aim is to study the mitofusin-1 in the follicular fluid as a marker for evaluating of oocyte maturation in women undergoing ICSI cycles. Fifty infertile females were included in cross-section study was undergoing ICSI procedure with age 20 to 42 years. After retrieval of oocyte and the number of oocytes was recorded by embryologist and follicular fluid Samples were used for the measurement of Mitofusin 1. Mitofusin 1 levels by ELISA kit (Mybiosource /USA).The results showed considerable higher mitofusin-1levels in patients with good oocytes quality (3.71 ± 1.35 vs. 2.45 ± 1.12 & p=0.001). There were much positive correlations between follicular fluids mitofusin-1 with both total oocytes count (r= 0.374 & p= 0.007) and MII oocytes (r=0.383 & p=0.006); and there was no much correlation between mitofusin-1 levels with MI oocyte (r= - 0.100 & p= 0.490), germinal vesical oocyte (r=0.103 & p= 0.475) and fertilization rate (r= 0.054 & p= 0.711). High follicular fluid levels of Mitofusin 1 may positively impact oocyte development and pregnancy rate.
The estimation of oocyte quality in human in vitro fertilization (IVF) is an important point for the embryologists. Oocyte selection and the identification of the best oocytes may help to limit an overproduction of embryos and to improve the results of oocyte cryopreservation programs. The follicular fluid (FF) can be provided easily during oocyte pick-up and known to represents an optimal source for non-invasive biochemical predictors of oocyte quality. However, till now no substance was found to be used as reliable markers of oocyte competence to fertilization, embryo development and pregnancy. Metabolism and ATP levels within the oocyte and adjacent cumulus cells are associated with quality of oocyte and optimal development of a healthy embryo. Lipid metabolism provides a potent source of energy and its importance during oocyte maturation is being increasingly recognised. Objectives: To determine the effect of lipids (Cholesterol. Triglyceride and HDL) level in serum and follicular fluid in predicting oocyte quality, embryo quality and outcome in patients undergoing intracytoplasmic sperm injection program Patients and Methods: Fifty eight (58) infertile women with an age range 21-41 years old undergoing intracytoplasmic sperm injection cycles were included in this study. Lipids (Cholesterol. TG and HDL.,) levels in serum and follicular fluid were measured by auto analyzer for biochemistry (Flexor El_200) and correlation with oocyte quality, embryo quality and ICSI outcome was done. Results: The results of this study showed no significant (p<0.05) difference in lipid levels in serum and follicular fluid between pregnant and non pregnant females as well as non significant correlation was found between lipid level in serum and follicular fluid in relation to oocyte quality and embryo quality. Conclusions: Serum and follicular fluid lipids are not good predictors of oocyte quality, embryo quality or ICSI outcome in women undergoing IVF/ICSI cycles. Accordingly, these biomarkers would be less reflective of the follicular environment and that the effect of maternal metabolic disorders on oocyte quality and fertility outcome is complex and of a multifactorial kind.
Reactive oxygen species (ROS) are believed to play an important role in the function of the male and female reproductive system, as well as in embryonic development. If the balance between production and elimination of ROS is disturbed, pathogenic consequences would happen. Reactive oxygen species can sometimes exert damaging effects when overabundant, oxidative stress is hypothesized to have a negative impact on, for example, folliculogenesis, embryo development, oocyte maturation, oocyte fertilization, endometriosis, polycystic ovary syndrome and unexplained infertility .8-Hydroxy2-desoxy guanosine (8‐OHdG) is a sensitive indicator of DNA damage as a result of oxidative stress. The study aim was to evaluate follicular fluid levels of 8-Hydroxy2-desoxy guanosine in patients undergoing Intracytoplasmic Sperm Injection (ICSI) and compared the results between both pregnant and non-pregnant patients . One hundred and twenty-seven women included in this study, they underwent controlled ovarian hyper stimulation, program followed by ova pick up, at that time follicular fluid were obtained and freezes till the time of analysis for reactive oxygen species (ROS), patient injected oocyte was cultured in CO2 incubator, then embryo grading, embryo transfer, pregnancy rate and reactive oxygen species level were determined. Follicular fluid 8-OHdG was significantly lower in pregnant females (p < 0.001), 8-OHdG had negative correlations with grade 1 and grade 2 embryos and negative correlation with total blastocyst count. Follicular fluid levels of 8-OHdG provides sensitive tool to predict positive pregnancy outcome in women undergoing ICSI.
Background: Many studies found that the Glycyrrhiza glabra (G.glabra) showed a positive effect on the activation of sperm in vitro specifically improve the activity of progressive movement. However, it was not known the impact of this stimulant on the certain sperms parameters in vasal obstructive mammals. Objectives: This experiment was designed to examine the possibility of fertilization ova by epididymal sperm of vasectomized mice activated by G. glabra and study the early embryonic development, as a model for obstructive azoospermia. Methods: Glycyrrhiza glabra aqueous extract (0.3 mg/ml culture medium) was used for in vitro direct sperm activation technique. The superovulated female mice (SUO) were divided into two groups, the first group; the insemination of flushed ova was performed with epididymal sperm of vasectomized male mice activated by adding30% of G. glabra to the culture medium (treated group).While the second group,the ova were inseminated by epididymal sperm of vasectomized male mice activated by G. glabra - free medium (control). Results: This study showed a highly significant (P <0.01) improvement in certain sperm function parameters i.e the sperm forward movement, morphologically normal sperms (MAS). There was a significant (P<0.05) increase in fertilization rate (FR) of SUO mice oocyte using 30% G. glabra medium(75.84%) compared to G. glabraFree medium (Hams -F12 medium) alone (54.43%).By adding 30% G. glabra to the medium, the number of 3-cell and 4-cell embryonic stage of SUO mice was significantly (P <0.05) higher than that of grouping G. glabra- Free medium mice embryo(62.10% and 65.78% vs. 58.88 and 66.29%, respectively). Conclusion: This study showed a highly significant (P <0.01) improvement in certain sperm function parameters i.e the sperm forward movement, morphologically normal sperms (MAS). There was a significant (P<0.05) increase in fertilization rate (FR) of SUO mice oocyte using 30% G. glabra medium(75.84%) compared to G. glabraFree medium (Hams-F12 medium) alone (54.43%).By adding 30% G. glabra to the medium, the number of 3-cell and 4-cell embryonic stage of SUO mice was significantly (P <0.05) higher than that of grouping G. glabra- Free medium mice embryo(62.10% and 65.78% vs. 58.88 and 66.29%, respectively).
Various types of anesthetic techniques were described for oocyte recovery. Different anesthetic agents have been used with different effects on oocyte quality and embryonic development and studies on the potential toxicity of general anesthesia ended up with conflicting results. Many experiments as well as human studies documented the existence of anesthetic agents in the follicular fluid (FF) with possible adverse effects on the oocyte quality and subsequent embryo development. Ketamine and remifentanil were used for the studied groups to compare oocytes and embryos characteristic of infertile women during oocytes retrieval under general anesthesia: one group receiving ketamine, midazolam, and propofol and the other group receiving remifentanil, midazolam and propofol. 60 infertile females were undergoing intracytoplasmic sperm injection categorized in two groups, group I received midazolam, remifentanil and propofol; whereas, group II received midazolam, ketamine and propofol. There was highly significant difference in mean abnormal oocyte between ketamine and remifentanil groups. Grade III embryos were significantly limited to ketamine group. FF ketamine and remifentanil were not significantly correlated to any of oocyte characteristics or embryo characteristics. Anesthetic agents, ketamine and remifentanil, were detected in the FF of infertile women and within recommended doses. Ketamine resulted in adverse effects on oocyte and embryo quality in comparison with remifentanil represented by greater percentage of abnormal oocytes and that bad quality embryos were limited to ketamine group.
Preeclampsia-eclampsia still continues to be one of the major causes of maternal and fetal mortality and morbidity. Recent evidence suggests that there may be several underlying causes or predispositions leading to develop this syndrome, which not only affects the mother but significantly affects the fetal growth and development.The objective of the study was to assess the difference in birth weight in pregnancy with and without preeclampsia . A case – control study at Al-kadhmya teaching hospital The study included 200 pregnant women with singleton viable gestation presented in labor who were admitted to hospital.A comparison of 100 women in the preeclamptic group and 100 women in the non-preeclamptic group in terms of maternal age, parity, gestational age at delivery, placental weight, and fetal birth weight and sex. Detailed obstetric and general medical history was taken and general and obstetric examination performed. The newborn infants were carefully examined and weighed, and the APGAR score was assessed after delivery. The fresh placenta was examined and then weighed with the membranes and cord attached.At low placental weight, preeclampsia had significant association with low birth weight (35%). However, at high placental weight, preeclampsia had non-significant association with high birth weight (4%). Birth weight of neonatal case group was close to birth weight of control group especially at late onset of preeclampsia but this was not significant statistically .Preeclampsia is multisystemic disorder and it is (the disease of theories) these result suggest that preeclampsia may represent different entities with different degree of placental involvement and different degree of fetal growth and development.
Background: The effects of Lead and other essential metal like zinc and copper on the reproductive system have been previously reviewed. Objective: Our goal in this study was to estimate the levels of Lead, Zinc and Copper in patients with polycystic ovary syndrome and to confirm the effect of such metals on the female reproductive system at environmental exposure. Materials and Method: Fifty two women in their reproductive age (20-40) years old, which had been diagnosed as PCOS. Venous blood sample were taken from each patient and control, blood lead, zinc and copper were determined by atomic absorption spectrophotometer. Hormone assay were determined by ELISA (Enzyme Linked Immune Sorbet Assay) technique. Results: This study showed a significant increase of blood lead and serum zinc, copper (p<0.01), in addition to testosterone, lutenizing hormone, LH/FSH ratio and body mass index (BMI) (p<0.05) in patients with polycystic ovary syndrome when compared with control. Conclusions: On the basis of the observations of the present study, it can conclude that the increased levels of Lead as a result of the exposure to this metal may be a risk factor for the development of polycystic ovary syndrome in women and has adverse effects on female endocrine and reproductive function.
Background: Superovulation in mice causes a delayed embryonic development in vitro and in vivo, an increased abnormal blastocyst formation, pronounced fetal growth retardation. Objective: Morphometric measurements the dimensions (thickness, length) of fetal kidney and suprarenal gland during the later intrauterine life, after superovulation induction. Methods: Twenty five mature female mice Swiss-Webster mice, these mice were divided into two groups: experimental (G1) (15animal/group) and control group(G2) (10 animal/group). Superovulation was induced by intraperitoneal (IP) injection of 7.5 IU of PMSG,then followed by 7.5 IU of HCG after 48 hours. Ovulation was taken place between 122± hours after injection of HCG. One mature male mice was placed with three superovulated female mice for mating. Pregnant females were sacrificed on gestational day eighteen in all experimental groups. For morphometric study 20 mice embryos were fixed in Bouin>s fixative, longitudinal sections of whole embedded embryo were stained by H&E, the specimens independently read. The dimensions (thickness, length) of fetal kidney and suprarenal gland were evaluated. Results: The statistical analysis showed significant decrease (P<0.01) in weights of fetuses in comparison with control group. The study was showed significant decrease (P< 0.01) in fetal kidney dimensions at day 18 of intrauterine life, when it compared to the fetal kidney of non superovulated group(control group). There was also significant decrease (P< 0.01) in the morphometric measurements of fetal suprarenal gland dimensions. Conclusion: The study improve that there is a delay in growth of kidney and suprarenal gland in fetal mice that belongs to mother undergo to superovulation induction before pregnancy.
Monosodium glutamate (MSG) is a widely used flavor enhancer in many foods. However, excessive consumption during pregnancy may adversely affect embryonic development and reproductive functions. This study aimed to investigate the effects of maternal MSG consumption during pregnancy on pregnancy outcomes and the reproductive system of female offspring in mice. Thirty adult pregnant female mice, aged 42–49 days, were used in this study. The animals were equally divided into two groups: an experimental group (G1) and a control group (G2). The experimental group received MSG extract orally at a dose of 1 mg/kg body weight dissolved in 1 ml of distilled water (D.W.) throughout the three weeks of pregnancy, whereas the control group received 1 ml of distilled water alone for the same duration. After delivery, litter size and litter weight were recorded. Forty days after birth, the weights of the female reproductive organs were measured, and the diameters of the ovaries and oviducts were assessed. In addition, blood samples were collected for the evaluation of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) levels in both groups. The experimental group showed a significant reduction in litter size and a significant decrease in litter weight compared with the control group. Female offspring born to MSG- treated mothers also exhibited a significant decrease in reproductive organ weight, ovarian diameter, and oviduct diameter. Furthermore, significant reductions in the levels of FSH, LH, and estradiol were observed in the experimental group. Maternal consumption of MSG during pregnancy may negatively affect pregnancy outcomes and impair the development and function of the reproductive system in female offspring.
During the process of embryo development, endometrial receptivity is very important for the successful implantation of blastocysts. This research investigated the influence of endometrial thickness on the day of oocyte retrieval and fresh embryo transfer on pregnancy outcomes in Iraqi women who are undergoing intracytoplasmic sperm injection (ICSI). Women from Iraq are taking part in this investigation. Participating in in vitro fertilization (IVF) cycles with the use of ICSI was a group of 44 women who were diagnosed with polycystic ovarian syndrome (PCOS) and had unexplained infertility. During the phases of oocyte retrieval and embryo transfer, there were significant differences seen between the two groups (p-values of 0.003 and 0.049), respectively. There was a total of 44 individuals, and 31 of them had negative pregnancy test results. The remaining 13 persons had positive findings. These results illustrate the importance of endometrial thickness in influencing the effectiveness of assisted reproductive technologies in achieving pregnancies.
Background: Analysis of human reports and comparison with results of exper-imental animals indicate that the effects of progesterone on human not analo-gous to experimental animals fetus, many studies showed that exposure to pro-gesterone during developing of genital tract of human fetus was not teratogenic. Other studies which performed on laboratory animals found association between progesterone administration during gestation and genital malformation. Objectives: to explore the effect of progesterone in 10.2mg/kg intraperitoneal injection in mice on testis development and anogenital distance. Materials and Methods: ten pregnant mice divided into five mouse control group that injected10.2mg/kg sesame oil and treated group that injected proges-terone at dose 10.2mg/kg/day allover gestation to the seventh day postnatally, mice offspring sacrificed, the anogenital distance, weight and diameter of testis were measured ,histological slides were prepared and examined for histopatho-logical change and measurement of seminiferous tubules diameter, germinal epithelium thickness and interstitial space were done . Results: the current study found anogenital distance decrement and histopatho-logical changes in mice offspring testis as hemorrhage or congestion of blood vessels ,irregular shapes of seminiferous tubules with atrophy, detachment of spermatogenic cells from basement membrane, death of spermatogenic cells and destruction of Sertoli and leydig cells ,it is also showed wider interstitial tissue and thinner germinal epithelium. Conclusions: The present study indicate study that progesterone injected in mice at dose 10.2 mg/kg /day (the equivalent human dose allover gestation was em-bryotoxic and teratogenic, it may cause feminization of male offsprings repre-sented by decrement the anogenital distance in mice and hypospadias in human .
Background: The effects of taking oral contraceptive pills that contain steroid hormones (estrogen and progesterone) during pregnancy on some aspects of fetus and newborn have been previously reviewed. Objectives: The objectives of this study are to detect the effect of using different doses of progestin and estrogen (contraceptive pills OCPs) by pregnant female mice on the gonadal development of their male fetuses, and on their pregnancy outcome. Materials and Methods: Ninety female mice were divided equally into three major groups: two experimental (G1 and G2) and control group according to the level of the dose. Administration of OCPs (either 0.034 or 0.068 mg/kg b. wt. /d dissolved with 0.1ml distilled water) orally once a day, were started at the first day of gestation and continued till day 14 for the experimental groups G1 and G2 respectively. When the female in each experimental and control groups reach day 17 of gestation, 15 animals of each group were sacrificed, whereas the other 15 animals were left to be sacrificed at birth time. Weight and numbers of fetuses were recorded, in addition, histological study for their testes were done. Results: The statistical analysis showed a highly significant (P<0.01) decrease in weights and numbers of fetuses (males and females), and highly significant decrease ( (P<0.01) in the testes diameter of fetuses belonged to mothers treated with normal and double dose of OCPs at day 17 and at birth time. In addition, fetuses belongs to G2 mothers revealed testicular undescending to its normal position and remained adjacent to the kidneys at the upper part of the abdominal cavity in comparison with control group. Conclusion: Administration of steroid hormones orally to pregnant female mice for 14 days causes a highly significant decrease in the weight and number of fetuses at day 17 and at birth time and cause negative effect on the diameter of the fetal testes. The OCPs can inhibit at its high dose, the descending of the testes to its normal location at the pelvic cavity and then to the inguinal canal.
Gestational diabetes mellitus (GDM) is a serious pregnancy complication in which a woman who has never had diabetes develops chronic hyperglycemia during her pregnancy. Normal placental function is essential for optimal fetal growth. The transport of glucose from the mother to the fetus is critical for fetal nutrient demands and can be stored as glycogen in the placenta. However, the function of this glycogen deposition is unknown: It may well be a source of fuel for a placenta itself or the storage reservoir for the later use by the fetus in times of need. While the significance of the placental glycogen remains unknown, the mounting evidence indicates that the altered glycogen metabolism and/or deposition is associated with many pregnancy complications, such as gestational diabetes, that adversely affect fetal development. The aim of this study is to assess glycogen deposition using Histochemical staining of Periodic Acid Schiff (PAS) stain. The placenta tissue collected from 50 women were enrolled in this study (25 women with no complications) and (25 women with gestational diabetes). The placentas of the two groups were compared in this study based on glycogen deposition with periodic acid-Schiff stain. The results of a histochemical investigation using PAS stain revealed a significant increase in the glycogen deposition (p≤0.001) in diabetic women's placentas within the intervillous core, around fetal vessels, and the basement membranes.
Granulosa cells produce most ovarian function indicators in infertile women like estradiol, AMH, and inhibin B. Female peptide hormone insulin-like factor 3 is produced by theca cell. Signaling of insulin-like factor 3 from theca cell stimulates antral follicle development and theca androgen production. To investigate how INSL3 levels may be a theca cell marker of ovarian reserve and the association with current markers of ovarian reserve, including AFC, FSH, E2, and AMH, in infertile women undertaking assisted reproduction. In this cross-sectional study, 75 Iraqi infertile couples were chosen at Al-Nahrain University's High Institute for Infertility Diagnosis and Assisted Reproductive Technologies from October 2022 to April 2023 for the ICSI cycle. Based on the levels of INSL3 in the serum on the day 2 of the menstrual cycle and on the day of retrieving oocyte in the follicular fluid. A comparison was made with current ovarian reserve markers (AFC, FSH, E2, and AMH) .From 75 infertile women undergoing intracytoplasmic sperm injection (ICSI), 21 of them achieved pregnancy. Positive Significant relations were found between serum INSL3 levels and anti-mullerian hormone (AMH and antral follicle count. there were no significant relationships between follicular fluids INSL3 with serum LH, FSH and E2 . The study provides compelling evidence for the significant role of INSL3 in female fertility and its association with the success of intracytoplasmic sperm injection (ICSI). Positive correlations between serum INSL3 levels and anti-mullerian hormone (AMH) and Antral follicle count AFC indicate its potential involvement in ovarian reserve and hormonal regulation.
Background: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. Polycystic ovary syndrome signs and symptoms often begin soon after menarche. In some cases, PCOS develops later during the reproductive years, for instance, in response to substantial weight gain. The PCOS produces symptoms in about 5-10% of women of reproductive age(12-45 years) and it is one of the leading causes of female subfertility.Women with PCOS suffer not only from subfertility, but also from a high rate of early pregnancy loss. About 30-50% of clinically confirmed early pregnancy loss are associated with PCOS.In addition to early pregnancy loss, women with PCOS have increased risk of recurrent miscarriage ,which defined as 3 or more consecutive pregnancy loss before 20 week. Metformin hydrochloride, an insulin sensitizing agent, has been shown to have encouraging effects on several aspect of PCOS like insulin sensitivity, plasma glucose concentration & lipid profile.It is found that using Metformin during pregnancy in women with PCOS may reduce the pregnancy loss and also reduce the risk of gestational diabetes,intrauterine growth retardation(IUGR) & preterm labor. Aim of study: To evaluate the role of Metformin in women with recurrent miscarriage & its effect on other pregnancy complications in women with PCOS. Patients, Materials & Methods: A prospective study done at gynecology outpatient clinic of AL-Batool Teaching Hospital in Baquba-Diyala -Iraq, from September 2012 to September 2016. A total of 100 cases were studied, all have aconfirmed diagnosis of PCOS depending on the following criteria:1)Oligo or amenorrhea (8 or fewer cycles per a year) , 2) signs of hyperandrogenism 3)ultrasound features of PCOS.All should have history of 3 or more recurrent first trimester miscarriage & they were invistigated for other causes of recurrent miscarriage. All cases were followed before getting pregnant and received Metformin for enhancing fertility & when they become pregnant, they were divided into two groups: the 1st group stopped using Metformin once they get pregnant while the 2nd group continued to use Metformin in a dose of 500-1000mg per day throughout pregnancy .Both groups are followed to determine pregnancy outcome. Results: Patients who continued to receive Metformin during pregnancy had better pregnancy outcome regarding early pregnancy loss and recurrent miscarriage, gestational diabetes development, IUGR & preterm labor. Conclusions: Metformin use during pregnancy improve pregnancy outcome in patients with polycystic ovary syndrome.
One-half of the genome is delivered by the sperm, and a healthy sperm is needed for fertilization, fetal development, and child wellbeing. Abnormal sperm DNA can impact any of these processes. The measurement of sperm DNA fragmentation has been added to some medical andrology laboratories as a crucial addition to the standard analysis of the semen. Sperm DNA fragmentation has also been linked to male infertility including idiopathic male infertility. Some degree of controlled DNA nicking is essential for adequate DNA compaction, but excessive sperm DNA fragmentation is usually associated with reduced male fertility potential, reduced fertilization, poor embryo quality, recurrent pregnancy loss and poor assisted reproductive techniques outcomes. Semen samples from 50 infertile males (as 19 asthenozoospermia, 7 oligozoospermia, 13 normospermia and 11 combined defects) were analyzed for sperm DNA fragmentation. This study followed the World Health Organization 2010 guidelines to assess the sperm parameters. Sample were collected by masturbation and put in a 37 °C incubator to be liquefied, then they were placed in a centrifuge (3000 rpm for 10 min) to extract the pellet, which was used for assessment of DFI% by anillin blue staining. Negative significant correlation (p = 0.023) between morphologically normal sperms and DFI % was found in normozoospermia group. The objective of this study is to examine the correlation of DFI among different seminal fluid categories (normozoospermia, oligozoospermia, asthenozoospermia and, combined).
Background: Azoospermia is defined as the lack of sperm in male ejaculate and is suggested to be present in about 1 % of all males and to account for 10-15% of the causes of infertility in men. The development of intracytoplasmic sperm injection (ICSI) as an effective therapy. Embryo grading has gained special attention in published literature regarding its predictive role in pregnancy outcome following ICSI; however, substantial controversy is present that justified the carrying out of the present study. Objective: To study the association between embryo quality and pregnancy rate in women of males with azoospermia. Patients,Materials and Methods: This prospective cohort study included 60 patients with azoospermia, 15 male with obstructive type and 45 males with non-obstructive type.Those patients were randomly selected form the population of infertile couples who regularly visits the High Institute for Infertility Diagnosis and Assisted Reproductive Technologies and from Kamal Al-Samarrai Hospital -Center for Infertility Treatment and IVF. Results Pregnancy was encountered in 7 patients (23.33%). It was not statistically associated with type of azoospermia (P=0.388), also it was not affected by age and serum hormonal level, but highly determined by good quality of embryo. Quality of embryo was graded from 1 to 4. The lower the grade, the better the quality of the embryo was. Quality of embryo was not significantly correlated with type of azoospermia, age and hormonal levels. Conclusions Good quality of embryo is a significant predictor of positive pregnancy outcome in ICSI and the quality of embryo is not affected by age of male patient or type of azoospermia.
Despite many improvements in Assisted reproductive techniques during the last three decades, clinical pregnancy and live-birth rates still nearly 30–40% and 20–30%, respectively. To enhance endometrial receptivity many attempts done one of the endometrial scratching could provoke delay in endometrial maturation reforms asynchrony between endometrium and the concepts and indeed induce wound healing by producing a considerable raise in the local secretion of pro-inflammatory cytokines and growth factors like Heparin Binding Epidermal Growth Factor (HBEGF) and its receptors has role in mediate the receptivity, maturation, and decidualization of endometrium and facilitates the implantation and development of both placenta and embryo. All women were undergone IUI procedure. They divided into two groups. Intervention group who did endometrial scratching by using pipelle catheter in luteal phase of preceding cycle and another blood sample aspirated before scratch. Control group include women without intervention of endometrial scratch. Both groups underwent controlled ovarian stimulation, triggering of ovulation and another blood sample was aspirated at day of IUI to measure level of HBEGF. 14 days later with luteal support, BHCG test underwent in blood to check pregnancy. Higher pregnancy rate among patients with scratch group (5/20) 25% than non-interventional group (3/25)12%. These result showed that HBEGF level in scratch group (386.1±124.7) is significantly higher than control group (279±189.3) as P-value was (0.035). Moreover, the HBEGF level at day of IUI (455.67±157.34) and in pregnant (563.9±163.66) is significantly higher than before scratch in scratch group (279.0±124.67), (406.26±138.89), as P-values were (0.00007, 0.049) respectively. Intentional local damage to the endometrium is a cost–effective procedure can be used to enhance the uterine receptivity that may help to overcome implantation failure problem.
Reactive oxygen species (ROS) are active chemical compounds created by the body's metabolic process and are crucial in human reproduction. Excessive ROS can contribute to oxidative stress, which has been linked to poor fertility. Embryo culture medium plays an essential role in IVF/ICSI cycles. Eighty participants underwent ovarian stimulation and ICSI cycles; ROS levels were measured in blood samples on the ovum pickup (OPU) day and in each embryo culture dish on ET day using enzyme-linked immunosorbent assay (ELISA). These values were associated with the quality of generated embryos. Women were divided into two groups; the first had day three embryo transfers, whereas the second received blastocyst transfers on day 5. Grades I embryo count was shown to be inversely related to the serum and culture medium ROS levels. Pregnant women had significantly greater levels of GI embryos (p=0.011) and lower levels of GIII embryos (p=0.024). Pregnancy rates for the third-and fifth days of the embryo transfers were 24% and 50%, respectively, with (p=0.045). Pregnancy success rates were increased after ET day five and were strongly influenced by transfer day. Blastocyst-stage embryos with high serum ROS levels were found to be underdeveloped. Culture medium ROS levels can be used as an adjuvant criterion for embryo selection and metabolic marker for developing embryos.
Back ground: Optimal IVF and embryo culture conditions depend on the composition of culture media being the most important determinants of successful in vitro interaction of the gametes and subsequent embryo development. ATP is fundamental factor to maintain the life, by providing energy, and controlling the cell function and metabolism. Objective: To investigate the effect ATP supplied to culture medium on fertilization rate and in mice as model for human being. Materials and Methods: The female mice (90) were superovulated using superovulation program (SOP) to produce large number of oocyte were divided into three groups, G1 inseminated with vassal sperm in vitro alone (control) , G2 inseminated with vassal sperm in vitro using SMART enriched with ATP(1.25mM). While, G3 inseminated with vassal sperm in vitro using SMART medium enriched with ATP (2.5mM). Mouse spermatozoa were collected from both vas deferens. Then sperm parameters were assessed after 30 min. IVF technique was performed for 3 groups. Results: The results of the present study appear, significantly increment (P<0.05) in the IVF (%) was observed when using 2.5 mM ATP as compared to 1.25 mM ATP and control group. Conclusions: The result showed that addition of high ATP concentration (2.5 mM) enriched to the culture medium improved percentage of in vitro fertilization.
Stem cell factor (SCF) is one of the first growth factors derived from granulosa cells in the ovarian follicle plays a critical role in hematopoiesis and the generation of melanocytes and germ cells. SCF also serves an important role in the development of the interstitial cells of Cajal in the intestine and the learning functions in the hippocampal region of the brain. This study aimed to investigate the levels of SCF in follicular fluid (FF) and if it can be used as a potential marker for predicting oocyte, embryo quality, and pregnancy rate. A total of 44 infertile couples involved in the study. All of them underwent controlled ovarian hyperstimulation for the ICSI cycle. Antagonist protocol was used as an ovulation induction protocol. Patients were divided into two groups according to ICSI outcomes as pregnant (23 women) and non-pregnant (21 women) groups. A comparison was done in both groups based on the oocyte, embryo quality, and other ICSI cycle characteristics, and follicular fluid stem cell factor level. SCF level was measured by using an enzyme-linked immunosorbent assay. Our study showed lack of association between patients' characteristics which included (age, BMI, infertility duration, type of infertility, and causes of infertility, basal hormonal, stimulation characteristics levels), FF SCF level and the oocyte characteristics comparison (total number retrieved oocyte, germinal vesicle oocyte (GV), MI oocyte and MII oocytes, and the number of injected oocytes, fertilization rate, and embryo characteristics) between pregnant and non-pregnant groups. The present study showed that Mean follicular fluid SCF was significantly lower in pregnant women in comparison with that of non-pregnant women, 135.92±38.96 pg/ml versus 185.15±63.58 pg/ml, respectively (P=0.003). Raised SCF level in FF harms ICSI outcome.
In human-assisted reproduction both partners need to be evaluated during counseling because causes of infertility are due to male factors and female factors. some body hormones play important role in fertile women and cortisol one of these hormones which is essential for normal ovulation, cortisol usually increases during the follicular phase of the menstrual cycle, play a role in the early stages of follicular development by their interaction with aromatase activity and granulose cell functions. To investigate the correlation of cortisol hormonal level in serum and in follicular fluid that relationship with age in women under Intracytoplasmic sperm injection outcome. Its randomized prospective clinical trial study performance conducting in the Higher Institute for Infertility Diagnosis and Assisted Reproductive Technologies / Al-Nahrain University, Baghdad-Iraq, during the period from November2021to June 2022. a total of Sixty-three Infertile Iraqi women, who planned to inter intrasytoplasmic sperm injection program. The blood sample and follicular fluid sample obtained from all infertile women inter intracytoplasmic sperm injection program to measure cortisol hormonal level at specific days of this study. There was increase in cortisol level in women aged between (30-40) years, So there was significant finding between cortisol level and this age group and there was increase in cortisol level in women aged < 30 years at the same day and no significant difference in cortisol level in women age more than 40. Significant differences in cortisol level appear in group of women age between (30-40) years, also the same result appears in group of women age more than > 40 years and no significant differences in cortisol level in women aged < 30. No significant differences in cortisol level in all age women group (30-40) years, <30 years ,and the women age > 40 years.
Background: Polycystic ovarian syndrome (PCOS) is one of the most common endocrine disorders among females in reproductive age. Women with PCOS have several cardiovascular disease risk factors. Hyperinsulinemia and insulin resistance (IR) which is a known key factor in the development of type 2 diabetes (T2DM) may associate PCOS. Homocysteine, a sulfur-containing amino acid, is toxic to vascular endothelium, leads to early atherosclerosis. PCOS said to be associated with high plasma homocysteine. Objective: To determine the correlation between insulin resistance and homocysteine in PCOS patients. Methods: Patients diagnosed as PCO according to Androgen Excess and PCOS Society/2009 criteria were grouped into two groups: those with BMI less than 30kg/m2 and those with BMI 30kg/m2 and more. Blood was drawn for biochemical and hormonal assay. Information tabulated, means and percentages used, and the results were analyzed. Results: Homocysteine levels were significantly higher (P value < 0.05) in PCOS group (12.28±1.89 µmol/l) as compared to control (9.51±1.92 µmol/l).HOMA-IR was significantly higher (P value < 0.05) in PCOS (4.15±2.54) as compared to control (1.69±0.54) .There was no correlation between IR and homocysteine within PCOS group. Conclusions: Polycystic ovarian patients have higher levels of homocysteine and IR compared to control but there is no correlation between IR and homocysteine within PCOS group.
Lead is a heavy metal toxicant, present widely in the environment and workplaces. Zinc has been shown to reduce the toxicity of lead. The present experimental animal study was designed to observe the changes in the testes due to excessive use of lead. This study aims to detect the effect of antioxidants (zinc) on the toxicity of high doses of lead on the reproductive organs of male mice embryos compared to the control group as a model for human representative. Thirty mature female mice were used (Swiss-Webster), as a mammalian model. They were divided into three groups, 10 mice/group after labelling them. They were randomly assigned into three experimental groups, and these embryos were processed for histological observations. The recorded results showed a severe disruption in the organization of testicular structure with primordial germ cells severely degenerated with the absence of basal lamina and peritubular myoid cells of the treated group (G1) compared with the control group at day 14 and day 17. The embryo testes of (G2) at day 14 showed irregular testes cords with prominent degenerative changes compared to that of the control group (G3). It was concluded from these results that zinc sulphate plays a significant role in the improvement of histological damage of the testes belonging to mothers injected with lead acetate and protects the reproductive organs from injury during lead toxicity.
Gonadotropin-releasing hormone antagonists are one of the GnRH analogs that were used in assisted reproductive technologies to produce prompt downregulation of pituitary gonadotropin secretion. During conventional antagonist protocol (CAP), exposure to high LH and E 2 occur that have the potential to worse clinical reproductive results. So the downregulation of pituitary secretion for short period during early follicular phase will result in synchrony in follicular developments and this will improve mature oocytes and total embryos numbers. 44 women as normal responders undergoing ICSI-ET cycles were randomized into two groups. The conventional group (CG) (n 30), gonadotropin started from menstrual cycle day 2 or 3 and continue until hCG trigger day, flexible protocol in which GnRH antagonists administered with follicular size (13-14 mm). In the sandwich group (SG) (n 14), a GnRH antagonist was administered for three days in which GnRH antagonists administered with follicular size (13-14 mm). Gonadotropin started from menstrual cycle day 3 and continue until hCG trigger day. Retrieved and MII oocyte mean numbers were significantly higher in SG than in CG ( P = 0.006, and 0.025), respectively. Embryos and frozen embryos mean total numbers were significantly higher in SG than in CG ( P = 0.004). SG patients have a higher pregnancy rate of 9/14 (64.3 %) than CG 12/30 (40.0 %) although not significant ( P =0.057). Early and short GnRH antagonists proved improvements in synchronization of follicular development, retrieved mature oocytes numbers, total embryos, frozen embryos, and pregnancy rates.
Background: The evaluation of ovarian reserve has been, and still, the focus of substantial clinical research. The assessment of ovarian reserve is valuable for determining stimulation protocols, and because of limited predictive value of age alone, or other passive hormonal analysis in estimating response to the exogenous stimulation, Dynamic research was done on serum inhibin B. Objective: Measurement of serum inhibin B as a predictive evaluation of early ovarian response following ovulation induction program in intrauterine insemination(IUI). Materials and Methods: Thirty couples were involved in IUI program. They divided into two groups: group (1) 15 women were treated by Gonadotropin(Gn) recombinant follicle -stimulating hormone (rFSH). While group (2), 15 women were treated by Clomiphene citrate (CC). Treatment started at day 3 of the menstrual cycle. Serial hormonal profile tests namely; Inhibin B, Estradiol (E2), Follicle-stimulating hormone (FSH), Luteinizing hormone (LH) were done at days 3, 7 of the menstrual cycle and the day of human chorionic gonadotropin hormone (hCG) injection with recurrent ultrasonography (US) to confirm the number and development of the follicles. Results: There was a significant difference in the level of inhibin B (P< 0.05) between day 3 and 7 of the cycle with the mean of the follicle number 1.67±0.18 in group(1), while in group (2) there was a non significant difference (P>0.05) in the level of inhibin B between day 3 and 7 of the cycle with the mean of the follicle number 2.14±0.17. Percentage of pregnancy rate in IUI in this study was 19.23%. Percentage of pregnancy rate in group (1) was 25%,while in group (2) was 14.28%,but there is a significant difference (P<0.05) in the pregnancy rate between the two groups. Conclusion: It was concluded that serum inhibin B obtained at day 7(day 5 of (Gn) therapy) offers an early and accurate prediction of ovarian response to (Gn) stimulation while there was no significant change in the level of inhibin B between day 3 and 7 of the cycle in patients treated by CC.
For conception and the development of healthy embryos, sperm DNA integrity is crucial. According to a growing body of studies, there is a strong correlation between sperm DNA damage and male infertility. Among the new medicines being developed in the medical field, the application of Platelet Rich Plasma (PRP) in human reproduction has yet to be examined. A total of 100 semen samples were used in the current experimental investigation. From November 2020 to June 2021, the research was conducted at the High Institute for Infertility Diagnosis and Assisted Reproductive Technologies. Masturbation was used to get an ejaculated semen sample. After semen analysis, the samples were separated into two equal parts, one without autologous PRP and the other with 2% autologous PRP, with the DNA fragmentation assessed using the Sperm Chromatin Dispersion Test. There was highly significant reduction in DNA fragmentation index (p < 0.001). The mean sperm DNA integrity was reduced after adding PRP (33.85±16.73 vs 38.55±16.64), Mean (± SE). PRP has been shown to improve human sperm DNA integrity.
