Testosterone patch improves ovarian follicular response to gonadotrophins in a patient with Kallmann's syndrome: a case report.

Achieving ovulation in women with Kallmann's syndrome requires both exogenous FSH and LH to successfully stimulate follicular maturation and ovarian steroidogenesis. We present a case of a woman with Kallmann's syndrome, who had poor ovarian response to stimulation by exogenous gonadotrophins. When she was given testosterone by patch before initiation of gonadotrophins, her stimulation dramatically improved. Once we ceased to pretreat her cycle with testosterone, she again had a poor stimulation. This suggests that testosterone administration may be a useful adjunct in improving ovarian response to gonadotrophins in Kallmann's syndrome patients.
