To investigate the relationship between the side of ovulation (right or left ovary) and its influence on fetal gender and placental localization. The study was conducted at the Nakhchivan State University Faculty of Medicine and the NMR Birth Center. Out of 178 women examined, a cohort of 39 patients was selected for detailed monitoring. Research methods included US-folliculometry, placentography, and ultrasound examination of the fetus and amniotic fluid. The study found that when fertilization occurred from an ovum produced by the right ovary (22 cases), the fetal gender was 86% male and 14% female. In these pregnancies, the placenta was located on the posterior wall in 75% of cases and on the anterior wall in 17%. Conversely, when fertilization occurred from the left ovary (17 cases), the fetal gender was 77.8% female and 22.2% male. In these instances, the placenta was positioned on the anterior wall in 71% of cases and on the posterior wall in 29%. The results indicate a significant correlation between the side of ovulation and both the sex of the fetus and the site of placental implantation. Right-sided ovulation shows a strong predisposition for male fetuses and posterior placental placement, while left-sided ovulation is predominantly associated with female fetuses and anterior placement.
