What is the effect of the early follicular phase FSH/LH ratio on the number of mature oocytes and embryo development?

Abstract

Background/aim: Basal level of follicle stimulating hormone FSH , luteinizing hormone LH , estradiol E2 , and antral follicle count are used as predictors of ovarian reserve before starting ovulation induction. We aimed to investigate the predictor potential of early follicular phase FSH/LH ratio on controlled ovarian hyperstimulation-intracytoplasmic sperm injection COH-ICSI cycle outcomes. Materials and methods: This retrospective cohort study was conducted with 648 COH-ICSI cycles performed between 2012 and 2014. Cycles were classified according to their basal FSH/LH ratio, group 1 G1 = FSH/LH ratio
