With the recognition, afforded by recent evolutionary science, that female infidelity was a recurrent feature of modern humans' evolutionary history has come the development of a unique area in the study of human mating: sperm competition. A form of male–male postcopulatory competition, sperm competition occurs when the sperm of two or more males concurrently occupy the reproductive tract of a female and compete to fertilize her ova. Males must compete for mates, but if two or more males have… 

Sexual conflict in humans: evolutionary consequences of asymmetric parental investment and paternity uncertainty

It is suggested that the source of much of the conflict between men and women can be reduced to an asymmetry in reproductive biology, which produces sex differences in minimum obligatory parental investment and paternity uncertainty.

Male materetention behaviors vary with risk of partner infidelity and sperm competition

New evidence is provided that men at greater risk of partner infidelity and sperm competition more frequently perform a variety of mate retention behaviors, such as calling unexpectedly to check up on their partners, monopolizing their partners’ time when around other men, and threatening other men who show an interest in their partners.

Ejaculate economics: an experimental test in a moth

It is shown that when rival males are present around a copulating pair, the male ejaculates more sperm to win a sperm competition battle but in such an environment he inseminates fewer females, sires fewer offspring and lives shorter.

Absence makes the adaptations grow fonder: proportion of time apart from partner, male sexual psychology, and sperm competition in humans (Homo sapiens).

A questionnaire to investigate psychological responses to the risk of sperm competition for 237 men in committed, sexual relationships predicted that a man who spends a greater proportion of time apart from his partner since the couple's last copulation reported greater sexual interest in his partner.

Toward a Biology of Collectivism

It is presently argued that such anatomical differences are a testament to a more peaceably monogamous mating history and that such physiological markers are directly associated with the collectivist ethos that has been historically, anthropologically, and sociologically observed among the Asian people.

Book Review: A Biased, Incomplete Perspective on the Evolution of Human Mating Systems

Several of the most telling examples of bias are addressed: the construction of a false mating system dichotomy, the discussion of female orgasm, and the charges of academic xenophobia against those who disagree with Dixson's conclusion that sperm competition played no selective role in human evolutionary history.

Sexual Conflict in Humans

This chapter provides an introduction to and brief overview of empirical and theoretical work on sexual conflict in humans, and discusses the application of evolutionary principles to psychology, with a focus on human psychology.

Is Cunnilingus-Assisted Orgasm a Male Sperm-Retention Strategy?

The results support Prediction 1 but not Prediction 2, and how these results may be more consistent with alternative hypotheses regarding female orgasm and oral sex is discussed.

Psychological and Physiological Adaptations to Sperm Competition in Humans

The authors consider, using evidence from contemporary societies, whether sperm competition is likely to have been a significant adaptive problem for ancestral humans and examine the evidence suggesting that human males have physiological and psychological mechanisms that allow for “prudent” sperm allocation in response to variations in the risk of sperm competition.

SPERM COMPETITION AND ITS EVOLUTIONARY CONSEQUENCES IN THE INSECTS

The possible advantages to a species of internal rather than external fertilization have frequently been stressed, though one important point appears persistently to have escaped comment. In terms of

Fertilization by proxy: rival sperm removal and translocation in a beetle

It is found that in the flour beetle Tribolium castaneum, the second male to mate gains fertilization precedence over previous males' sperm and fertilizes approximately two-thirds of the eggs and removed, non-self sperm may be translocated back into the reproductive tracts of new, previously unmated females, where the translocated sperm go on to gain significant fertilization success.

Sperm competition in humans

The classical theory that sperm are small simply because of the difficulties of ensuring that ova do get fertilized may also explain sperm size, and both effects are likely to contribute to the stability of anisogamy.

Human sperm competition: ejaculate adjustment by males and the function of masturbation

M masturbation is a male strategy to increase sperm fitness without increasing sperm numbers in the female tract as a function of risk of sperm competition; female reproductive value; and optimum partitioning of ejaculates between successive in-pair copulations.

Semen Displacement as a Sperm Competition Strategy in Humans

We examine some of the implications of the possibility that the human penis may have evolved to compete with sperm from other males by displacing rival semen from the cervical end of the vagina prior
