title: [Oxytocin and male sexual function].
abstract: Oxytocin (OT) is a female hormone with the main function of facilitating uterine contraction and milk ejection. Recent studies show that OT is involved in multiple signaling pathways in the central and peripheral nerve system and mainly regulates the physiology and activity of reproduction, including male reproduction and sexual behavior. The roles of OT in penile erection are bio-phasic with proerectile effect in the central nerve system while peripherally inhibiting erection. OT also mediates ejaculation, post-ejaculatory detumescence and the post-orgasm refractory period. OT and OT-receptor in the central nerve system will be a new target in the drug development for the treatment of erectile dysfunction, while OT intracavernous injection promises to be an effective therapy for priapism. This review focuses on the effects of OT on male sexual activities.
