*Select patients with less than the median value served as the reference group. The median value for the antral follicular count, FSH, E2, PRL, and LH was 24, 5.74, 38.65, 14.95, and 7.02, respectively.

FSH, follicle-stimulating hormone; E2, estradiol; P4, progesterone; LH, luteinizing hormone; PRL, pituitary prolactin; BMI, body mass index; ICSI, intracytoplasmic sperm injection.
