[Prolactinoma in the male. Therapeutic results in 40 men]

Forty male patients with a prolactinoma were operated on by the transsphenoidal approach. Postoperative normalization of PRL levels occurred in 37% of the cases, in 100% of the microadenomas and 68% of the adenomas with preoperative PRL levels below 700 ng/ml. None of the invasive tumors were normalized. Partial hormonal deficits were produced by surgery in three cases and panhypopituitarism in one case.
