Cigarette smoke contains a substance which is a toxic mutagenic chemical, and carcinogenic compounds, which have a negative effect on male fertility. Smoking cigarettes is associated with noticeably higher levels of the oxidative stress-causing reactive oxygen species in the seminal fluid. Because of this, smoking may cause changes to the sperm plasma membrane and a significant amount of deoxyribonucleic acid fragmentation. To study the influence of smoking on sperm chromatin immaturity and ICSI outcomes (fertilization rate, embryo grading and pregnancy rate). At the laboratories of the High Institute of Infertility Diagnosis and Assisted Reproductive Technologies and after 1-7 days of sexual abstinence, 92 males’ sperm samples were taken. After liquefaction, macro-and microscopic studies were carried out, criteria applied by the WHO 2021. Masturbation was used to obtain the sample, which was then placed in sterile containers. The relationship between the smoking and chromatin immaturity and ICSI outcomes have been evaluated. A significant positive correlation between smoking status and sperm chromatin immaturity. Furthermore, there was a negative non-significant correlation between smoking status and fertilization rate. Weak and non-significant correlations between smoking status and embryo grade 2 as well as embryo grade 3. There was a positive association between smoking status and embryo grade 1. The sperm chromatin integrity was significantly lower in the non-smoker group compared to the smoker group.
Endometriosis is a chronic inflammatory gynecological disease and a leading cause of female infertility, characterized by Th1/Th2 cytokine imbalance. Interleukin-13 (IL-13) and Interferon-gamma (IFN-gamma) are cytokines mediating anti-inflammatory and pro- inflammatory pathways, respectively, and were investigated in this study in infertile women with endometriosis undergoing Intracytoplasmic Sperm Injection (ICSI).To explore the potential impact and prognostic value of Interleukin-13 (IL-13) and Interferon- gamma (IFN-gamma) on ICSI outcome and to confirm their role in endometriosis-related infertility .A prospective case-control study was conducted involving 80 infertile women aged 18-40 years, including (n=40) women laparoscopically confirmed with endometriosis and (n=40) infertile women without endometriosis serving as controls. Both groups enrolled in ICSI cycles, and on the day of oocyte retrieval, serum and follicular fluid were collected; then concentrations of IFN-γ and IL-13 were quantified using enzyme-linked immunosorbent assay (ELISA). Ovarian stimulation characteristics, oocyte maturity, embryo quality, maturation rate, fertilization rate, and pregnancy rate were compared between groups using appropriate statistical analyses to investigate their association with endometriosis and their impact on ICSI outcomes. Elevated IFN-γ and IL-13 levels in both serum and follicular fluid are strongly associated with impaired ovarian response and poor ICSI outcomes in women with endometriosis. These findings suggest that inflammatory cytokine imbalance contributes to reduced oocyte developmental competence and embryo quality. Assessment of IFN-γ and IL-13 may provide clinically valuable biomarkers for predicting ART outcomes and could facilitate individualized therapeutic strategies targeting immune-mediated reproductive dysfunction.
Obesity induces metabolic dysfunctions in bodily systems and is a significant health challenge. Excessive adipose tissue accumulation encompasses dynamic, endocrine, and biologically active processes. The fundamental pathogenic mechanism of obesity is chronic low-grade inflammation exacerbated by pro-inflammatory biomarkers such as free fatty acids, lipopolysaccharides, adipokines, and cytokines. The rising prevalence of obesity over the past forty years has led to an increase in associated comorbidities, including polycystic ovarian syndrome (PCOS). To clarify the impact of increasing body mass index (BMI) in PCOS and non PCOS on the ICSI outcomes of 143 infertile Iraqi females, dividing them into two main groups: PCOS and non PCOS and each group into normal weight and overweight/obese group. Group 1= normal BMI PCOS, group 2= overweight/ obese PCOS, group 3= normal BMI non PCOS, group 4= overweight/obese non PCOS. Significant differences in ICSI outcomes were observed in the PCOS groups compared to the non-PCOS groups concerning the total number of harvested, MI, MII oocytes, GV, abnormal and fertilised oocytes, total and D3 grade I embryos alongside higher number of arrested and transplanted embryos. There are numerically higher number of D3 grade II and III embryos, morula and blastocyst with no significant difference seen. The rates of maturation and fertilisation exhibited no significant disparities. The biochemical pregnancy rate was higher in group 2 compared to group 1, and in group 4 compared to group 3, with a statistically significant difference. A higher BMI among younger PCOS individuals may be associated with better pregnancy outcomes.
Infertility is the disability of a couple to obtain pregnancy after one year of sexual intercourse that is unprotected and regular. Bisphenol A is an industrial chemical spread worldwide, that is a raw material utilized in multiple industries. Bisphenol A is assorted as an endocrine-disrupting chemical, which can interfere with hormone activity. This study aimed to assess the effect of BPA levels in serum on ICSI outcomes. The study was conducted at the High Institute for Infertility Diagnosis and Assisted Reproductive Technologies / Al-Nahrain University during the period from October 2021 to April 2022. sixty infertile women enrolled in this study. BPA levels were analyzed through an enzyme-linked immunosorbent assay (ELISA) technique. Mean serum BPA was not significantly higher in non-pregnant women in comparison with that of pregnant women. Serum BPA was positively correlated to immature oocytes (MI) and abnormal oocytes. Also, BPA inversely correlated to Grade1 embryos and positively correlated to Grade 3 embryos. Bisphenol A can be detected in sera of infertile female undergoing ICSI. High BPA level in serum may impact oocyte quality and embryo grading
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.
There is a relation between adipose tissue and macrophages. These macrophage cells influence adipose tissue by releasing many bioactive chemicals, including the wingless-type MMTV integration site family 5a (wnt5a) glycopeptides and the more traditional cytokines. Healthy adipocytes can release the wnt5a inhibitor Secreted frizzled-related protein 5(SFRP5). However, this protective effect was found to be reduced in obesity. This study aimed to assess the effect of follicular and serum levels of SFRP5 as well as serum and follicular levels of wnt5a on ICSI outcome and determine the potential roles of SFRP5 as a predictor of positive pregnancy in Iraqi infertile females undergoing ICSI with different body mass index .Ninety infertile females who received intracytoplasmic sperm injection and had various infertility factors between 18 and 45 years participated in this prospective clinical cross-sectional study. Follicular fluid, serum SFRP5, and serum and follicular fluid wnt5a levels were measured for all participants on the day of ovum pickup. In addition, ICSI outcomes were determined. There was a significant difference in the mean total gonadotrophin dose used among the three studied groups (p = 0.023), higher in overweight and obese females than normal-weight females. There was a positive significant correlation between serum plus follicular fluid wnt5a and total gonadotropin dose. Serum and follicular fluid SFRP5 levels were significantly higher in normal-weight females. There were higher serum (p-value=0.002) and follicular fluids (p-value=0.005) SFRP5 levels in pregnant females. Both SFRP5 and wnt5a glycoproteins were detected in infertile women's serum and follicular fluid. Serum and follicular fluid secreted frizzled-related protein 5 level positively associated with ICSI outcome. The cutoff values for serum and follicular fluid SFRP5 were ≥15.86 (ng/ml) and ≥ 11.3(ng/ml), respectively, as predictors of positive pregnancy in women undergoing IVF/ICSI cycles. Obesity, BMI, SFRP5, wnt5a, ICSI Outcome
The selection of protocols in controlled ovarian stimulation during intracytoplasmic sperm injection affect the treatment outcomes. Both GnRH agonist and GnRH antagonist protocols are clinically utilized, therefore comparision of these protocols is important for the evaluation of their laboratory and clinical outcomes.To compares the short GnRH agonist and GnRH antagonist protocols effectiveness in expected normal responder females undergoing intracytoplasmic sperm injection (ICSI). Methods: A retrospective study was involved 60 women aged less than 35 with antimullerian hormone (AMH) more than 2.5 ng/ml. Participants women were assigned to either group1 short GnRH agonist protocol and group2 GnRH antagonist protocol. The outcomes measured including total oocyte, mature and immature oocytes, number and quality of embryo and pregnancy rate.The short GnRH agonist protocol group showed statistical significant benefit in oocyte yield (p- value 0.04), metaphase I (p- value 0.09), metaphase II (p- value 0.03), embryo number (p- value 0.04), embryo quality (p-value 0.01) and pregnancy rate in expected normal responder women compared to GnRHantagonist protocol. The short GnRHagonist protocol reveals favorable ICSI outcomes than antagonist protocol and may be better choice in expected normal responder women.
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.
EMMPRIN (Basigin) is a potent inducer of matrix metalloproteinases (MMPs). Expression of EMMPRIN in the uterus has a very important role in implantation of embryo, this study was conducted to evaluate the relationship of pregnancy rates with EMMPRIN levels in follicular fluid and serum of intracytoplasmic sperm injection patients. The study was cross sectional study analyzed the serum and follicular fluid samples of 58 patients undergo ICSI procedure. The serum and follicular fluid samples were collected from infertile women aged 20 to 42 years. However, the levels of EMMPRIN were measured in the serum and follicular fluid samples and these samples were obtained during oocytes retrieval and another serum samples were collected at the day of embryo transfer. All women have ovarian stimulation with recombinant follicle stimulating hormone (FSH) at the second or third day of the cycle. Result: The pregnancy rate was 27.6 %. The present study showed that EMMPRIN in serum and follicular fluid at day of ova pickup and its level at embryo transfer day, are significantly low in pregnant women (p < 0.05) compared to non-pregnant women. The statistical analysis showed no significant correlation between serum and follicular fluid EMMPRIN with endometrial thickness (p > 0.05). EMMPRIN level can be used as a promising parameter for the prediction of pregnancy rate in ICSI cycles.
