The compromise of uterine receptivity is one of the main reasons for the failure of assisted reproduction techniques. Leukemia inhibitory factor is one of those molecular parameters that allow us to identify an endometrium as receptive. Platelet rich plasma (PRP) contains a range of cytokines and growth factors including leukemia inhibitory factor that encourage the migration, proliferation, and differentiation of cells. Treatments for antagonist ovarian stimulation were administered to 75 women under the age of 40, and 2-D power doppler ultrasound was used to guide the oocyte harvest. Patients were allocated into three groups according to the time of intrauterine infusion of PRP (no PRP, PRP at triggering day and PRP at ova pickup day). Power Doppler is utilized to measure endometrial thickness (ET), pulsatility index (PI), and resistance index (RI) of sub endometrial arteries, as well as serum levels of leukemia inhibitory factor (LIF). The mean endometrial thickness as well as serum level of LIF in PRP trigger group were higher, resistance index and pulsatility index were lower in a significant manner than control and PRP ova pickup group at all the days of study (triggering, ova pickup and embryo transfer days). These findings revealed that intrauterine PRP infusion on ova pick up day is associated with a significant increase in serum level of LIF that in turn enhances endometrial thickness for patients scheduled for intracytoplasmic sperm injection (ICSI).
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.
