Core Tip

Core tip: Less is known about the association between endogenous opioids and sexual function and behaviors in humans. There are mixed reports regarding the impact of oxytocin on sexuality and romantic relationships. The importance of physiological changes during sexual activity and how they can affect human relationships and the gaps in the literature highlight the need for high-quality research to extend our understanding of the hormonal physiology of sexual function and the role of endorphins and oxytocin in human sexuality.
