Is oxytocin an undeservedly forgotten hormone in men?

Oxytocin is one of the most ancient mammalian hormones in terms phylogeny. Over more than 100-year history his scientific study, views on biological functions oxytocin humans have undergone a significant and even revolutionary changes. For long time, this neurohypophysis hormone, which formed hypothalamus only deposited it (central synthesis), was associated exclusively with female reproduction aspect labor, breastfeeding maternal behavior. However, over past decades, unique extensive base has been created confirming universal nature effects both sexes, predetermined by presence additional peripheral sites secretion men women, as well an receptor apparatus many cells tissues, together allows to function endocrine central auto- paracrine local signaling pathways. This fact convincingly proves that much wider range physiological body results modern research allow us consider neuropeptide multifunctional hormone great social significance for humans. The review article briefly discusses endocrinology detail its men, including role sexual behavior, erectile function, protection from stress, reproduction, metabolism, prostate gland.
