Abstract

The Role of Prolactin in Men

Marinaki Maria

The role of prolactin in women is quite documented while the man studies are conflicting. In this review we will study the structure, receptors, secretion factors, biological effects of prolactin in men. Previous studies in men associate hyper-prolactinemia with infertility, erectile dysfunction, reduced testosterone, decreased sexual desire as rarely galactorrhea. Originally had not been investigated low prolactin levels in the male but recent studies indicate that the hypo-prolactinaemia in men is associated with infertility, erectile dysfunction, hypo function of the seminal vesicles, oligospermia and asthenospermia. Recent studies indicated that 1 or 2 years after the bariatric surgery levels of the hormone prolactin reduced.
