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.
Female infertility is caused by ovulation issues, tubal disorders, uterine abnormalities, endometriosis, and peritoneal factors. For years, intrauterine insemination has been used to treat infertility alone or with ovarian stimulation. Obtaining adhesion ligands and losing inhibitory components are necessary for pregnancy. LIF promotes and differentiates proliferation and differentiation in embryonic, hematopoietic, and endothelial cells. LIF also controls prostaglandins (PGs), which mediate implantation and decidualization. The measuring hormone profile on cycle day 2 before control ovarian stimulation including FSH, LH, E2, Prolactin, TSH, and AMH. Serum LH, E2. The progesterone level was estimated on the day of triggering. The effect of LIF gene genotypes on hormone level. The hormone levels of 100 intrauterine inseminated women were measured on the second day of the cycle and the day of ovulation. DNA extraction for LIF gene variation detection utilizing sequencing and HRM. The current study found no significant differences between pregnant and non-pregnant groups for hormone levels, genotype, and genetic effect on female hormone levels with (P ≥0.05). The LIF gene did not affect hormone levels in infertile females may be due to the tiny samples or the complex signaling chain that happens during implantation.
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.
Intrauterine insemination (IUI) comprises the insertion of a high number of washed and processed spermatozoa directly into the cervix to the uterine cavity around the time of ovulation to increase the chances of pregnancy. It is usually used for couples with mild male factor infertility, unexplained infertility, cervical factors, mild endometriosis, and psychological, sexual dysfunction. The endometrium, which lines the uterus, is prepared for the implantation of the embryo; this process starts in the proliferative phase and extends throughout the luteal phase. Implantation, a crucial phase of pregnancy, is a complicated process, and more than half of failures to achieve pregnancy are caused by implantation failure. To assess the influence of endometrial flushing of 1000IU hCG done prior to IUI procedure on pregnancy rate in infertile females undergoing IUI treatment. The present study was applied to 80 infertile subjected to ovarian stimulation protocol using letrozole and hMG in doses adjusted according to their response; triggering was done using subcutaneous HCG. The results of the present study showed no significant difference regarding initial characteristics, indication for IUI, basal menstrual cycle characteristics, ovarian stimulation characteristics, and semen parameters before and after processing, while there was a significant difference between both groups regarding biochemical and clinical pregnancy rates. In IUI cycles, endometrial human chorionic gonadotropin (hCG) flushing done 5-10 minutes prior to IUI can improve biochemical and clinical pregnancy rates.
