Evolutionary Perspectives on Hypoactive Sexual Desire Disorder in Women

Abstract

This review attempts to explain female hypoactive sexual desire disorder (HSDD) from a functional evolutionary perspective. Can theory and data regarding the evolved functions of female sexual motivation help explain cases of low sexual desire in women? If so, might some such cases be the product of brain mechanisms operating in ways that promoted reproductive success during human evolution, rather than low desire resulting from pathology? A functional theory of women’s sexual motivation is first summarized, which posits that sexual desire is modulated by both conception probability and social variables related to the initiation and maintenance of pair bonds. Recent evidence consistent with this theory is reviewed, followed by review of evidence showing that variables predicting sexual desire in most women may also explain cases of HSDD. Women’s sexual desire varies in functionally patterned ways. Discovering the evolved design of brain mechanisms that generate those patterns is crucial for understanding HSDD.
