title: Ovarian failure without gonadotropin elevation in a patient with post-traumatic isolated hypogonadotropic hypogonadism.
abstract: A woman with secondary amenorrhea following head trauma showing isolated gonadotropin deficiency of hypothalamic origin did not respond to massive doses of hMG therapy (11 250 IU daily dose). Ovarian biopsy showed the absence of follicles, despite persistently low FSH levels. In this case the occurrence of premature ovarian failure was only suspected from the lack of response to hMG and diagnosed by ovarian histology.
