title: [Ovulation induction by the chronic administration of naltrexone in a patient with secondary hypothalamic amenorrhea].
abstract: An ovulatory cycle was induced by oral administration of a specific opiate antagonist: naltrexone, at a dose of 50 mg/day for 26 days in a woman suffering from secondary hypothalamic amenorrhea. The follicular growth was monitored by ultrasound and serial blood measurement of LH, FSH, E2 and progesterone. The hormonal and ultrasound profiles showed an ovulatory cycle with a single dominant follicle. After discontinuation of the treatment, the patient became amenorrheic again. The gonadotropin as well as estradiol plasma levels declined, to that observed before treatment. Naltrexone may be a useful agent for induction of ovulation in women suffering from hypothalamic amenorrhea.
