Laboratory Measurements
Serum levels of follicle stimulating hormone (FSH), luteinizing hormone
(LH), testosterone (T), estradiol (E2), Anti-Müllerian
hormone (AMH), fasting insulin and fasting plasma glucose were
determined, as previously reported19. To define
insulin resistance, homeostasis model assessment (HOMA-IR) was made
using the equation: fasting glucose (mmol/L) × fasting insulin
(mIU/L)/22.5.
