Whether women’s orgasm is an adaptation is arguably the most contentious question in the study of the evolution of human sexuality. Indeed, this question is a veritable litmus test for adaptationism, separating those profoundly impressed with the pervasive and myriad correspondences between organisms’ phenotypes and their conditions of life from those who apply the “onerous concept” of adaptation with more caution, skepticism or suspicion. Yet, the adaptedness of female orgasm is a question… 

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 parallel

Evolutionary Science of Female Orgasm

TLDR
Evidence that female orgasm functions as a mechanism for choosing mates of high genetic quality, investment potential, or both is presented, and directions for future research are outlined that will help to resolve the debate about the functionality of orgasm in women.

Testing the mate-choice hypothesis of the female orgasm: disentangling traits and behaviours

TLDR
This is the first study to test within-woman variation in orgasm and partner traits and some assumptions and predictions of mate-choice hypotheses of female orgasm were supported, while other aspects of the findings provide reasons to remain sceptical.

Female orgasm has been a mystery that psychologists have been attempting to understand for decades. Many have contended that female orgasm is a functionless by-product of male orgasm, while others

An evolutionary behaviorist perspective on orgasm

TLDR
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).

Understanding the Prevalence of Sexual Dysfunctions in Women: an Evolutionary Perspective

Epidemiological studies indicate that almost one in two women face some kind of sexual dysfunction. Given the importance of sexual functioning for successful reproduction, such a high prevalence is

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

TLDR
Results suggest that male satisfaction with, investment in, and sexual fidelity to a mate are benefits that favored the selection of orgasmic signaling in ancestral females.

What is orgasm? A model of sexual trance and climax via rhythmic entrainment

  • A. Safron
  • Psychology
    Socioaffective neuroscience & psychology
  • 2016
TLDR
A novel mechanistic model of sexual stimulation and orgasm is introduced wherein sexual stimulation induces entrainment of coupling mechanical and neuronal oscillatory systems, thus creating synchronized functional networks within which multiple positive feedback processes intersect synergistically to contribute to sexual experience.

The Case of the Female Orgasm: Bias in the Science of Evolution

Why women evolved to have orgasms - when most of their primate relatives don't - is a persistent mystery among evolutionary biologists. In pursuing this mystery, Elisabeth Lloyd arrives at another:

The Evolution of Female Orgasm: Adaptation or Byproduct?

TLDR
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.

Human female orgasm and mate fluctuating asymmetry

Clitoral and penile size variability are not significantly different: lack of evidence for the byproduct theory of the female orgasm

The evolutionary significance of the female orgasm is unclear. Adaptationist accounts seek to ascribe a positive fitness benefit to females that achieve orgasm during vaginal intercourse, spawning

Of Bugs and Boojums: Female Orgasm as a Facultative Adaptation

TLDR
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.

Clitoral variability compared with penile variability supports nonadaptation of female orgasm

TLDR
A comparison in variability of aspects of male and female genital structures that supports differential selection on genitalia and thus likely differential Selection on male andFemale orgasm is presented.

Human oestrus

TLDR
It is proposed that the term oestrus appropriately applies to this phase of female sexuality occurring near ovulation, and ways that fertile-phase sexuality in women has been shaped to partly function in the context of extra-pair mating are suggested.

Female coital orgasm and male attractiveness

TLDR
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.
