Context: Tonic hypersecretion of luteinizing hormone (LH) appears to impact both fertility and pregnancy outcomes in women with polycystic ovary syndrome (PCOS). Aim: Whether high basal day 2/3 serum LH levels and day 2/3 LH/follicle-stimulating hormone (FSH) ratio affect in vitro fertilization (IVF) cycle outcomes in PCOS patients undergoing controlled ovarian hyperstimulation using gonadotropin-releasing hormone (GnRH) antagonists. Settings and Design: A retrospective cohort study was conducted in Assisted Reproductive Technique Center, Department of Obstetrics and Gynaecology, at a tertiary care institute, on PCOS patients undergoing IVF/intracytoplasmic sperm injection (ICSI) using GnRH antagonist protocol with human chorionic gonadotropin trigger between January 2014 to December 2019. Methods and Material: Data related to patient's age, body mass index, day 2/3 serum FSH, serum LH, day 2/3 LH/FSH ratio, and infertility treatment-related variables were collected from the patient record files. IVF cycle characteristics, number of oocytes retrieved, number of embryos transferred were also recorded. The clinical pregnancy rate per embryo transfer was calculated. Statistical Analysis: Statistical software SPSS IBM version 24.0 was used to analyze the data. Descriptive statistics such as mean, standard deviation , and range values were calculated. To compare the difference between the groups, the paired t-test was applied for continuous variables and the Chi-square test for categorical variables. A value of P < 0.05 was considered statistically significant. Results: High basal day 2/3 LH level and day 2/3 LH/FSH ratio have no statistically significant effect on embryos formed, embryo transferred, and clinical pregnancy rate. However, fertilization rates were significantly less in these groups. Conclusion: The elevated basal day 2/3 LH and LH/FSH ratio do not impair the outcome of GnRH antagonist protocol treated IVF/ICSI cycles in PCOS women.
