Women with hypothalamic amenorrhea that respond to leptin treatment and have their reproductive function restored show a distinct hormonal profile when compared to non-responders. This hormonal profile is characterized by higher LH/FSH ratio, apparently due to the central effects of leptin on GnRH secretion in hypothalamus. Responders also have higher peaks of E2 and Inhibin A in blood, which indicates improved ovarian function and restoration of normal regular menstrual cycles. Additionally, circulating AMH, which serves as an additional marker of ovarian recovery, is reduced.
AMH: Anti-mullerian hormone; E2: Estradiol; FSH: Follicle-stimulating hormone; GnRH: Gonadotropin-releasing hormone; LH: Luteinizing hormone
