[Hyperprolactinemia: I. Etiopathogenesis, clinical features]

Hyperprolactinemia is a frequent endocrinological disorder, which can develop in women as well as in men. Constant or periodical increase of prolactin concentrations in serum is an evidence of functional or organic damage of the hypothalamic-pituitary axis. Hyperprolactinemia features are complex, and lead toward hypogonadotropic hypogonadism. A shortened luteal phase, infertility and anovulatory cycles are clinical features in women. In men hyperprolactinemia leads to disorder of spermatogenesis (oligospermia, azoospermia) and infertility, too.
