Is Female Orgasm a Covert Mate Choice Mechanism

Cross-species data suggest that female orgasm depends on the quality of a female’s mate and evolves where females copulate polyandrously, and orgasm frequency tracks conception risk across the cycle, another indicator of a sire choice function.

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.

Do Female Sex Fantasies Reflect Adaptations for Sperm Competition?

Researchers have suggested that female strategies for sexual selection in humans include the promotion of sperm competition. Sperm competition entails the simultaneous presence of fertile sperm from

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

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 rate increases with male dominance in Japanese macaques

The findings suggest that the proximate mechanisms that control orgasmic threshold in female macaques are more responsive to social stimuli and less constrained by physiological limitations than previously thought.

The Functional Design and Phylogeny of Women’s Sexuality

Research findings indicate that women’s estrogen-based sexual ornaments honestly signal residual reproductive value, which supports the hypothesis that concealed estrus is adaptation that functions in extra-pair-bond copulation to cuckold the main partner in service of better genes for offspring, while maintaining the main partners’ material benefits.

It was found that asymmetry was correlated with measures of sexual selection including canine dimorphism, canine size, mass dimorphistan, and intra-male competition, however, there was no significant correlation with diet type and body mass, which are only weakly associated with sexual selection.

Female swallow preference for symmetrical male sexual ornaments

Male swallows with elongated, symmetric tails mated earlier, and enjoyed larger annual reproductive success than did males with shortened tails and increased asymmetry, which suggests that females in their mate choice use ornament asymmetry and size as reliable indicators of male quality.

The data suggest that, in purely monandrous situations, females reduced the number of sperm retained, perhaps as a strategy to enhance conception during periods of infidelity.

Cryptic Female Choice and Its Implications in the Scorpionfly Harpobittacus nigriceps

Female choice in the Australian scorpionfly Harpobittacus nigriceps, a species in which males provide females with a nuptial arthropod gift during mating, was studied in the field and laboratory and leads to stronger sexual selection on males than premating choice.

Female preference for symmetrical males as a by-product of selection for mate recognition

Simple, artificial neural networks are used to show that mating preferences for symmetry are likely to arise in the absence of any link between symmetry and quality, as a by-product of selection for mate recognition.
