We describe successful ovulation induction with low-dose hCG administration in addition to hMG in a patient with refractory hypothalamic amenorrhea. A 24-year-old woman with weight loss-related amenorrhea underwent ovulation induction and intracytoplasmic sperm injection (ICSI). Administration of exogenous gonadotropins was ineffective in ovulation induction. Supplementation with low-dose hCG in order to increase luteinizing hormone (LH) activity in the late follicular phase produced late folliculogenesis and steroidogenesis, and ovulation was then successfully induced. This report reacknowledges the critical role that LH plays cooperatively with follicle-stimulating hormone in both folliculogenesis and steroidogenesis.
