E ndometrial thickness (ET) is one of the best predictors of implantation rate and pregnancy success rate because endometrial growth depends on hormones. Estrogen regulates the proliferative phase, endometrial proliferation induced by estrogen after menstruation is largely dependent on blood flow to the basal endometrium that produces progesterone receptors which are required for progesterone-regulated endometrial growth in the secretory process. To compare the effect of estradiol valerate vs. sildenafil citrate on endometrial receptivity and subsequent pregnancy outcome in unexplained infertility patients receiving letrozole for ovulation induction. Herein, 21 patients with unexplained infertility underwent ovulation induction by letrozole (2.5 mg). Patients were divided into 2 groups; group A (10 patients) were given sildenafil tablets vaginally (25 mg) four times daily and group B (11 patients) were treated with estradiol valerate tablet 2 mg/12 hours. Patients were evaluated by transvaginal ultrasonography (TVS) to determine endometrial thickness, pattern, size, and the number of the dominant follicles, serum assessment of Vascular Endothelial Growth Factor (VEGF) level at trigger day, and chemical pregnancy outcome 14 days later. Results showed that the endometrial thickness, patterns of the endometrium, VEGF, size of the dominant follicle at the trigger day, and pregnancy rates were not significantly different between the two groups. However, the difference in the number of the dominant follicles at trigger day was statistically significant which is more in the sildenafil treated group. The present study confirmed the findings of both Sildenafil and E 2 valerate to boost endometrial receptivity and pregnancy rate.
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.
Background: Infertility is a common social and health problem. Male factor is a major cause in 30% of infertile couples. Smoking is common at reproductive age and its effect on fertilitiy is still in controversy. Studying its effect on fertility helps in the management of infertility. Objectives: To assess the effect of smoking on serum sex steroidal hormones as well as on seminal plasma (SP) IL-2, IL-6 and conventional semen parameters in infertile men and their correlations between each other. Methods: Seventy male partners of infertile couples (30 smokers and 40 non-smokers) were involved in this study. The man was considered smoker if he had history of smoking of more than 10 cigarettes per day for at least one year. Semen analysis was done according to world health organization (WHO) 2010. Specific kits were used for measurement of serum testosterone, serum estradiol II, SP IL-2, and SP IL-6. Results: The median of SP IL-2 was significantly (p<0.05) higher in smokers than in non-smokers group and positively correlated with SP IL-6 in them. In addition, IL-2 was negatively correlated with semen volume, sperm motility and morphology, while IL-6 was negatively correlated only with sperm motility. However, there was no significant difference of serum sex hormones level or on semen parameters between smokers and non-smokers. Conclusion: Cigarette smoking affect cytokine levels in the seminal plasma but has no effect on serum sex hormones level or semen parameters.
Inhibition of luteinizing hormone (LH) by gonadotropin releasing hormone (GnRH) antagonist may lead to suboptimal response during ovarian stimulation. In addition, several studies suggest that low level of LH is associated with lowered fertilization and implantation rate and increased early pregnancy loss rate. The aim of this study is to study the effect of adding low dose human chorionic gonadotropin (hCG - 200 IU), as an LH supplement, to recombinant follicle stimulating hormone (rFSH) in a GnRH antagonist cycles in women undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment. Sixty-three infertile women undergoing IVF were randomly divided into two groups. One group was stimulated with the conventional stimulation protocol (rFSH alone), while the second group received 200 IU hCG in addition to rFSH in the late follicular phase (hCG + rFSH). Both groups' results including pregnancy rate, total dose of rFSH required, duration of stimulation, endometrial thickness, oocytes and embryos characteristic, serum hormone levels (Testosterone, Estradiol, Progesterone, and LH) and level of epidermal growth factor (EGF) were compared. The results show that pregnancy rate among the group of women who received the low dose hCG was higher than those who did not receive hCG. However, this difference did not reach statistical significance. Furthermore, other cycle outcomes and hormonal values were comparable between the two stimulation protocols.
Background: Male obesity is associated with physiological changes that can negatively affect male fertility. Obese men have demonstrated a 3-fold increase in the prevalence of oligozoospermia when compared with men with normal Body Mass Index (BMI). Objective: To find the correlation between Aromatase enzyme with the following hormones (follicle stimulating hormone(FSH), Luteinizing hormone(LH), Estradiol(E2), and testosterone) in the obese infertile male. Subjects, Materials and Methods: Seventy obese infertile male (patients) and twenty obese fertile male (control) are enrolled in this study. Aromatase enzyme, FSH, LH, E2 and testosterone hormones were measured in their serum. All serum samples were measured by ELISA method. Results: Median human cytochrome enzyme level was significantly higher in patients than in control group, 87.55+ 12.48 pg./ml versus 56.95+9.88 pg./ml, P= 0.014. In patients group, a significant positive correlation was found between human cytochrome enzyme, FSH, and LH. Conclusions: The present study showed clearly that male obesity negatively affects fertility through changes in hormone levels. The results suggest that increased estrogen because of aromatization in the fatty tissue, reflected through the increase in human cytochrome enzyme (aromatase), may be an important mechanism for the hypoandrogenemia and altered sperm parameters.
Background: Polycystic ovary syndrome is the most common, yet complex, endocrine disorder with principal features of anovulation, amenorrhea, ovulation-related infertility, polycystic ovaries, and obesity. Number of metabolic aberrations is now well recognized as a growing public health problem in PCOS as glucose intolerance, hyperinsulinemia and dyslipidemia. Objective: To investigate and analyze the anthropometric, hormonal profile and metabolic abnormalities of obese and non-obese women with this disorder. Materials and Methods: Sixty-five healthy Iraqi women serves as the control group and eighty-four infertile women divided into two subgroups depending on the BMI (< and ≥30 kg/m2) were studied. BMI, waist to hip ratio and waist to thigh ratio were measured. Serum levels of luteinizing hormone, follicle stimulating hormone, estradiol, testosterone, fasting blood glucose, and oral glucose tolerance test, and total lipid profile were measured. Results: BMI, waist/hip, waist/thigh ratio were significantly higher in PCOS than control women. Lower FSH level, higher LH and E2 levels, LH/FSH ratio, and lower E2/testosterone ratio was found in obese and non-obese PCOS. Higher blood sugar level, high cholesterol, triglyceride, LDL, VLDL and lower HDL levels in PCOS compared to control women. Conclusion: Obesity is a common finding of women with PCOS, but it is not part of the diagnostic criteria. Women with PCOS usually have the so-called centralobesity (Visceral adiposity), and therefore tend to have an increased waist-hip ratio (WHR) and waist to thigh ratio, regardless of the weight factor (i.e., in obese and non-obese). PCOS patients exhibited abnormal hormonal status and biochemical indices also regardless of obesity.
Infertility is prevalent among couples in our community, and a considerable number of cases of infertility are caused by tubal factors. The hysterosalpingography (HSG) technique is one of the most important tools for determining the patency status of the tubes. Nevertheless, this method has certain drawbacks that can be addressed with a less invasive alternative, such as hysterosalpingo-contrast sonography (HyCoSy) and hysterosalpingo- foam sonography (HyFoSy) .By enrolling subfertile patients undergoing hysterosalpingo- foam sonography (HyFoSy) or hysterosalpingo-contrast sonography (HyCoSy) procedures and subsequently undergoing intrauterine insemination (IUI), this study sought to evaluate the pregnancy rate in a large single center prospectively . Between January 2024 and January 2025, 100 women who underwent IUI as a therapy modality for infertility at the High Institute for Infertility Diagnosis and Assisted Reproductive Technologies in Kadhimiya city, Baghdad, were involved in this randomized controlled research. Those who underwent hysterosalpingo-contrast sonography with foam (HyFoSy) or HSG evaluation of the fallopian tube were included. The main results were a biochemical pregnancy test (blood test) and clinical pregnancy verified by ultrasonography at 6–8 weeks gestation . When comparing the HyFoSy and HyCoSy groups, the mean serum levels of estradiol, FSH, LH, prolactin, TSH, and testosterone did not differ significantly (p > 0.05). Differences in the mean length of infertility, the mean ova size, the mean ova count, the average endometrial width (ET), the average number of antral follicles (AFC), and the forms of infertility (p > 0.05). Sixty-eight percent of the HyFoSy group and forty percent of the HyCoSy group experienced successful pregnancies, with a significant difference (p = 0.005) . These results imply that HyFoSy might be better than HyCoSy when tubal evaluation is required before IUI, assuming they are validated in bigger multi-center trials. Future studies should investigate long-term results, such as live birth rates, and include a control group (IUI without prior tubal evaluation).
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.
The 5,10-methylenetetrahydrofolate reductase (MTHFR) enzyme is a key methionine and folate metabolism enzyme that is found in oocytes and embryos in preimplantation stages and plays a vital role in female reproduction.To assess the impact of MTHFR genetic polymorphisms (C677T and A1298C) on follicular stimulating hormone (FSH), luteinizing hormone(LH), Estradiol (E2), progesterone and antimullerian hormone (AMH) in female receiving intracytoplasmic sperm injection (ICSI), 85 infertile women undergoing ICSI treatment at the High Institute of Infertility Diagnosis and Assisted Reproductive Technologies in Baghdad, Iraq, were recruited. These patients had their MTHFR polymorphism genotypes examined, FSH, LH, E2, progesterone, and AMH levels were compared between groups. Furthermore, all demographic characteristics as well as ICSI outcomes were compared between pregnant and non-pregnant women. The research revealed no discernible variation between the means of FSH, LH, E2 and AMH with respect to the 219A>C(rs1801131) (A1298C) genotypes (p > 0.05). Progesterone level was significantly differed with high level found in CC followed by AA and AC. There was no statistically significant variation in hormonal features between CC, CT, and TT for A1298C, 219A>C(rs1801133). The demographic features (age, duration, type of infertility, cause of infertility and previous trial) were not notably different between women who were pregnant and those who were not. In women undergoing ICSI, the maternal MTHFR polymorphisms is not related to FSH, LH, E2 and AMH. MTHFR polymorphisms therefore don't offer useful information regarding the hormonal levels in our groups.
Background: The intra uterine insemination (IUI) still an easy, simple and effective method to overcome the infertility that resulted from different causes. Although the equipments and methods of assisted reproductive technologies (ART) were highly developed, the percentage of successful IUI live-birth not exceed 20-30%. Objective: The present study was aimed to elucidated the cut off values of in vitro sperm preparation technique, follicular number and size, endometrial thickness and hormonal profile that lead to successful pregnancy rate (PR)following IUI. Materials and Methods: In retrospective study, one hundred cases of infertile couples were in who were became pregnant following IUI at the Institute of Infertility Diagnosis and Assisted Reproductive Technologies, through the period from January 2007 to January 2010. Depending on the results of retrospective study, IUI was achieved for 100 infertile patients between August 2010and June 2011. The mean of significant prognostic variables were measured in both studies namely: age, type of infertility, type of sperm activation techniques, the protocol of ovulation induction medicine, the mean of hormonal status of Luteinizing Hormone (LH), Estradiol(E2), and number with diameter of follicles, endometrial thickness a cycle day before hCG injection. Results: The protocol of ovulation induction in IUI cycles by using clomiphene citrate(CC) and recombinant gonadotropin (rFSH) was significantly(p<0.05) improve the IUI results compared to CC alone or CC with PergonalS. The mean values obtained by ultrasonography namely; two follicles, and dominant follicle of 19.5mm in size with endometrium thickness of >9.5mm were gave significantly successful IUI outcome compared to other values. In prospective study similar results were obtained, therefore the overall pregnancy rate was 37% per cycle. Conclusion: The calculated data of successful IUI outcome from retrospective study gave a best pregnancy rate in prospective study which was 37%. Consequently, these results can be considered as guideline for physician who interest in assisted reproduction to have a success in IUI.
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.
