Background: Oligozoospermia is one of male infertility type which related with sperm lowering count in seminal fluid under limited reference. There are many factors leads to oligozoospermia like, congenital defects, endocrinal disorders, genetic abnormalities, immunological factors , life style , or in some cases unknown reasons. Immune and some non-immune cells produce immuno-chemical messengers proteins called (Interleukins) work as alerts proteins and contribute in immune body defend. These mediators found in all body fluids, also found in seminal fluid,and it’s presence of certain concentrations reflects the state of health of the body. Objective:Measure the level of interleukin-6 in fertile (normospermia) and infertile (Oligozoospermia). Materials and Methods: Microscopically and macroscopically ejaculates analysis according to WHO (2010) criteria for eighty -seven ejaculate from normospermia and oligozoospermia patients with age rang (21-47)yrs. , in duration of ( Nov-2013 to Mar-2014), study divide in to three groups according to the concentration ranges in to (normospermia > 15X 106 cells/ml), (Mild to Moderate Oligozoospermia 15-5 X106cells/ml) , (Severe Oligozoospermia< 5X106). Then store all samples in(-20 ) , IL-6 was detected through the (ELISA) specific way and kit . Results: Interleukin-6level is less in normospermia group than Oligozoospermia groups at (P<0.05), IL-6 level not correlated with sperm count, except weak correlation in severe group at (P≤ 0.05) and (t α=0.05). Conclusions: There are no correlation between IL-6 level and sperm cells concentration but the variation of interleukin-6 level among the groups indicate that some sperms parameters influence on interleukin-6 levels among the groups like sperm motility or morphology and also that the causative factors which lead to oligozoospermia also effect on IL-6 level and effect on spermatogenesis .
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.
The structural elements like the “blood-testis barrier” (BTB) and systemic and local tolerance mechanisms help to maintain testicular homeostasis, which shields germ cells and mature sperms from immune attack. Any damage to this barrier could result in an immune attack and may lead to infertility. This study aims to look at the correlation between male infertility and immunological factors (IL-17, IL-25, and anti-sperm antibody). During the months of October 2021 and July 2022, a total of 144 samples were taken from patients who sought to have infertility tested. The subjects' semen specimens were taken in order to perform the ELISA tests for IL-17, IL-25, and ASA. The levels of ASA, IL-17, and IL-25 differed significantly (P≤ 0.05) across study groups, according to the results of immunological parameters. The results of the correlation analysis revealed a strong positive association between IL-17 and IL-25, but not between those two interleukins and ASA. Although there was theoretically a positive link in this study, it was very weak and not significant. The findings suggest that IL-17, IL-25, and ASA influence seminal fluid parameters, which in turn affect male fertility.
Background: Obesity has been defined as abnormal or excessive fat accumulation that may impair health while the Body mass index (BMI) is a simple index of the weight-to-height ratio that is commonly used in classifying overweight and obesity in adult populations. Many semen parameters alteration can be ascribed to obesity like decreased sperm concentration, abnormal morphology, compromised chromatin integrity and abnormal motility. Many evidences showed an adverse effect of excess body fat on spermatogenesis. Methods: A total sample size composed of (70)infertile men were grouped into three groups according to published BMI ranges as follows: normal weight, overweight and obese.A single semen sample was collected for each infertile men.Heightin (m) and weight in (kg) were recorded on day of semen collection.BMI was calculated as BMI= Kg\m2. Sperm parameters evaluated according to World Health Organization guidelines.Quantitation of the IL-6 in seminal plasma were accomplished using commercially available ELISA kit. Results: In the current study, a positive correlation was found between body mass index and IL-6, on the contrary, a significant negative correlation was found among IL-6 level and progressive sperm motility and sperm concentration as well. Conclusion: There is an increase of IL-6 from the adipose tissue with increasing BMI. The IL-6 cause reduction of the sperm motility by increasing the level of ROS. The obesity reduces the spermatogenesis by androgenic deficiency results in low sperm concentration and motilitywhich it may be the main reason of their infertility.
Node-like receptor pyrin 3 is a tripartite protein composed of an amino-terminal pyrin domin (PYD), nucleotide binding NACHT domine, and a carboxy-terminal leucine-rich repeat (LRR) domine, and consider an intracellular sensor that detects a broad range signal and resulting in the formation and activation the NLRP3 inflammasome. This complex lead to the release of the inflammatory cytokines IL-1β, IL-18 which is important for host defense against invading pathogen. Modern evidence indicates that the NLRP3 inflammasome is involved in gestational hypertension. This study was conducted on fifty pregnant women and divided into two groups: 25 placentas from normotensive mothers having no hypertension before as the control group and 25 from gestational hypertension women as gestational hypertension group, obtained from the Department of Obstetrics and Gynecology in Almosil El Aam Hospital and Alkhanssa Teaching Hospital, Mosul city, Iraq. The placental tissue samples were collected from the central region and processed for an immunohistochemical technique to t h e expression of NLRP3 in placental tissue. The immunohistochemical study of t h e placenta of the gestational hypertension group showed the localization of NLRP3 protein and staining intensity in trophoblast, stroma, and endothelium villi were high quantification compared with placenta from the control group.
