Improvement of ejaculatory incompetence with bromocriptine in a man with prolactin-secreting pituitary tumor

We report a case of a prolactin-secreting pituitary tumor in a man whose characteristic findings were ejaculatory incompetence and no response of gonadotropin to clomiphene. After treatment with bromocriptine ejaculation was normal, gonadotropin responded slightly to clomiphene and the high level of plasma prolactin returned to normal. A Hardy operation was performed to remove the pituitary tumor. The patient continues to receive 2.5 mg. bromocriptine daily to maintain normal ejaculation.
