Orgasm

Abstract

Orgasm is a part of sexual biology best known and described in humans, however the trait in some form likely predates human lineage. It is particularly intriguing for its sexual asymmetry: while necessary for reproduction in men, it is not required for women to conceive. In this article, we first summarize what we know about the physiology of this neuro-endocrine event in women and men. We then review the main ideas about the function, origin and maintenance of orgasm, and finally briefly outline the research history of this intriguing topic, pointing out the ideas of consequence in the field.
