Management of male hyperprolactinemic hypogonadism.

A 30-year-old man with a prolactin secreting pituitary adenoma and hypogonadism was studied. Except for hyperprolactinemia, the results of his pituitary function tests were perfectly normal. Although the mechanism is uncertain, hyperprolactinemia alone may interfere with male reproductive function. The patient's impotence and infertility were successful managed with injections of human menopausal gonadotropins (HMG). Adverse interaction between gonadotropins and prolactin along the hypothalamic-pituitary-testis axis may be corrected by HMG injections in certain cases.
