Human Female Orgasm as Evolved Signal: A Test of Two Hypotheses

  title={Human Female Orgasm as Evolved Signal: A Test of Two Hypotheses},
  author={Ryan M. Ellsworth and Drew H. Bailey},
  journal={Archives of Sexual Behavior},
We present the results of a study designed to empirically test predictions derived from two hypotheses regarding human female orgasm behavior as an evolved communicative trait or signal. One hypothesis tested was the female fidelity hypothesis, which posits that human female orgasm signals a woman’s sexual satisfaction and therefore her likelihood of future fidelity to a partner. The other was sire choice hypothesis, which posits that women’s orgasm behavior signals increased chances of… Expand

Female copulatory orgasm and male partner’s attractiveness to his partner and other women
Abstract Women’s copulatory orgasm may function to retain sperm from men with “good genes”, one indicator of which is attractiveness, and one benefit of which is pathogen resistance. Women whoExpand
Evolutionary Science of Female Orgasm
The difficulty of inducing orgasm in women, its variability between women, and the lack of an obvious relationship with women’s reproductive success have led some researchers to conclude that femaleExpand
Beliefs About Gender Predict Faking Orgasm in Heterosexual Women.
How women's worldviews about gender relate to their faking orgasm behavior is assessed, finding that those who espoused anti-feminist values-that is, those high in hostile sexism-had faked significantly more orgasms over their lifetime compared to those Who espoused ostensibly positive but restrictive ideas of gender relations.

An evolutionary behaviorist perspective on orgasm
  • D. Fleischman
  • Psychology, Medicine
  • Socioaffective neuroscience & psychology
  • 2016
It is argued that intense sexual pleasure, especially orgasm, can be understood as a primary reinforcer shaped by evolution to reinforce behavior that facilitates reproductive success (i.e. conception through copulation). Expand
Chapter 7 Evolutionary Science of Female Orgasm
Despite decades of scientific study, the functional significance of the human female orgasm remains unsettled. Whereas male orgasm is usually coupled with ejaculation, there is no parallelExpand
Factors Influencing Sexual Vocalization in Human Females.
  • P. Prokop
  • Medicine
  • Archives of sexual behavior
  • 2021
Sexual vocalization was most frequent during penetration itself compared with other forms of sexual activities, which supports its signaling function and it seems that sexually less restricted females may use sexual vocalization to increase their sexual attractiveness to their current partner by means of boosting their partner's self-esteem. Expand
Faking Orgasm: Relationship to Orgasmic Problems and Relationship Type in Heterosexual Women
The findings suggest that faking orgasm has both dispositional and situational elements, and “Orgasmic problems” in partnered sex was a consistent and robust predictor of the occurrence and frequency of faking climax in different relationship types. Expand
Women’s Orgasm and Sexual Satisfaction in Committed Sex and Casual Sex: Relationship Between Sociosexuality and Sexual Outcomes in Different Sexual Contexts
Higher sociosexuality was associated with higher orgasmic function in casual sex and with lower sexual satisfaction in committed sex, and the importance of examining interactions between individual differences and contextual factors when studying women’s sexual outcomes is underscored. Expand
The Relationship Between Dimensions of Adult Attachment and Motivation for Faking Orgasm in Women
Both attachment avoidance and attachment anxiety were related to the use of faked orgasm as a means to avoid negative, shameful feelings and the intention to quickly end sexual intercourse through faking orgasm. Expand
Machiavellianism, pretending orgasm, and sexual intimacy
Abstract Machiavellianism is characterised by distrust, manipulation, and a willingness to exploit others. Previous research indicates that Machiavellianism is associated with a preference forExpand


Men's masculinity and attractiveness predict their female partners' reported orgasm frequency and timing
It has been hypothesized that female orgasm evolved to facilitate recruitment of high-quality genes for offspring. Supporting evidence indicates that female orgasm promotes conception, although thisExpand
Female coital orgasm and male attractiveness
Results support the hypothesis that women mated to more attractive men are more likely to report an orgasm at the most recent copulation than are women mating to less attractive men, after statistically controlling for several key variables. Expand
Human female orgasm and mate fluctuating asymmetry
The proportion of a woman's copulations associated with orgasm is predicted to be associated with her partner's fluctuating asymmetry, and a questionnaire study of 86 sexually active heterosexual couples supported this prediction. Expand
Why Women Have Orgasms: An Evolutionary Analysis
Although additional research is needed before firm conclusions can be drawn, it is found that the mate-choice hypothesis receives more support and female orgasm appears to have evolved to increase the probability of fertilization from males whose genes would improve offspring fitness. Expand
The Evolution of Female Orgasm: Adaptation or Byproduct?
This essay outlines why, unlike Caton (2006), it is not persuaded by Lloyd's argument that female orgasm is a nonadaptive byproduct of orgasm in men and defines female orgasm too narrowly, ignoring critical information about its affective aspects. Expand
The physiology of the female orgasm as a proximate mechanism
The dynamics of female orgasms were investigated and proposed as a possible proximate mechanism implicated in female mating strategies. Specifically, the role of female orgasm in motivating women toExpand
Of Bugs and Boojums: Female Orgasm as a Facultative Adaptation
Data on women’s orgasm frequencies contradict mate choice hypotheses for the evolution of female orgasm—and support the hypothesis that female orgasm is an evolutionary byproduct of male orgasm. Expand
Human female copulatory orgasm: a human adaptation or phylogenetic holdover
We thank Sarah Hrdy for her interesting and very helpful review of our original manuscript sent to her by Animal Behaviour and for her thoughtful comments on the final published paper (Thornhill etExpand
Orgasm as a Post-Copulatory Display
This letter attempts to highlight several features of orgasm which are consistent with a Darwinian interpretation, and proposes that female and male sexual responses be considered together since orgasm and other components of sexuality derive from reproductive activities. Expand
Enhancing relationships: understanding the feminine mystique of pretending orgasm.
The findings indicate that those females who have ever pretended orgasm became sexually active at a younger age and have been more sexually explorative than those Females who have not pretended orgasm. Expand
