title: Effects of long-term treatment with bromocriptine on pituitary prolactinoma in a male.
abstract: Poor surgical results are obtained when operating on large prolactinomas, especially when an extrasellar growth is demonstrated. Several groups have reported tumor regression following bromocriptine treatment. A case report is presented of a young hyperprolactinemic man with a large pituitary adenoma with suprasellar extension, normal visual fields, decreased libido, impotence, hypogonadism and azoospermia. This man was treated with high doses of bromocriptine for a period of 5 months. A significant improvement of potency libido and sperm concentration associated with radiological evidence of a marked reduction of tumor size was noted following suppressive treatment with this ergot alkaloid.
