The ability of human sperm to fertilize can be compromised both in vivo and in vitro by the toxins found in cigarette smoke, which can lower sperm mitochondrial activity and harm chromatin structure. The aim is to study the effect of smoking on the apoptotic marker (caspase-3) of human sperm. A cross-sectional study of 80 semen samples of sub-fertile men, were divided into smokers (35 patients) and non-smokers (45 patients). All the semen samples after seminal fluid analysis underwent HOST test and grading (A-G) according to the WHO 2021 criteria then the slides were smeared and stained with an immunocytochemistry kit for Caspase-3 apoptotic marker. There was no significant effect of smoking in the concentration of caspase-3 expression, in spite of the high presentation of both grades A and G in the smoker group ( p = 0.57, 0.56 respectively). Smoking has a negative impact on the DNA integrity of sperm as it increases the apoptotic marker within the smoker group.
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.
Placenta growth factor is, VEGF family member, a Pleiotropic Factor affects a variety of cell types and regulates various biological responses. PlGF is similar in structure and function to VEGF, and it amplifies VEGF's angiogenic actions. Ovulation stimulation during cycles of in vitro fertilization (IVF) for the management of infertility results in ovarian hyperstimulation syndrome (OHSS), an iatrogenic side effect. Considering potential roles of PlGF and its receptor (sflt-1) in angiogenesis, the association of these factors with OHSS among study women during controlled ovarian stimulation have evaluated in the present study. Comparative cross-sectional study including of 60 women who go through controlled ovarian stimulation. On oocyte retrieval day, their serum and follicular fluid were taken. The concentrations of PlGF and sFlt-1 were assessed using ELISA .Eighteen patients presented with ovarian hyperstimulation syndrome (OHSS) and 42 patients were no OHSS. There was significantly higher serum PIGF in women with OHSS patients as compared to women with no OHSS, 141.4 ± 11.8 versus 91.9 ± 5.4 respectively (p<0.001). Furthermore, Follicular fluid PlGF there was significantly higher in women with OHSS patients as compared to women with no OHSS, 163.4 ± 7.2 versus 91.1 ± 5.5 respectively (p<0.001). Additionally Follicular fluids PlGF/sFlt ratio significantly higher in women with OHSS patients as compared to women with no OHSS, 0.034 ± 0.01 versus 0.026 ± 0.01 respectively (p<0 . 001). On the contrary there was significantly lower serum and follicular fluid sFlt in ovarian hyper-stimulated patients These statistics show that serum and FF PlGF and PlGF to sFlt ratio higher in women with ovarian hyperstimulation syndrome (OHSS) patients as compared to women with no OHSS. So, the PlGF may be played an important a role in angiogenesis dysregulation.
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.
