Hyperprolactinemia syndrome in men

A total of 122 male subjects suffering from secretory infertility were examined. In 25 of them (20 percent) blood prolactin levels were above the norm. Measurements of basal prolactin levels and of its secretion in metoclopramide test helped distinguish two types of hyperprolactinemia syndrome, differing in the pattern of spermatogenesis disorders. Possible pathogenesis of individual types of hyperprolactinemia in men is discussed. Therapy with dopamine agonists (lisenyl, parlodel) was found most effective in Type I hyperprolactinemia syndrome, associated with essential prolactin hypersecretion and oligospermia.
