Sexual Coercion in Humans and Non-Humans

Sexual coercion is a form of reproductive behavior where one individual force another to engage in sexual activity against their will. Sexual coercion can occur in both human and non-human animals, and it is a complex and controversial topic in evolutionary psychology.

What is Sexual Coercion?

Sexual coercion can be viewed as an evolutionary technique some individuals use to boost their reproductive success. Men may engage in sexual coercion to maximize their chances of passing on their genes by gaining access to more sexual partners or guaranteeing that their present spouse bears their offspring.

The Sexual-Conflict Hypothesis

The sexual conflict hypothesis is another idea presented to explain sexual compulsion in humans. According to this hypothesis, sexual coercion may result from competing reproductive objectives between men and women. Men may be more motivated to participate in sexual coercion since they can father children with various partners. However, women may be more choosy in their mate selection because they carry the higher responsibility of reproduction and child-rearing.

Research on Sexual Coercion

According to research, sexual coercion in humans is influenced by several individual, societal, and cultural factors. Personality qualities, views towards sex and relationships, and past trauma or abuse may enhance the likelihood of engaging in or suffering sexual coercion. Gender norms, power differentials, and the objectification of women are all social and cultural variables that may contribute to the occurrence of sexual coercion.

Women and Sexual Coercion

It is vital to understand that men and women can perpetrate sexual coercion. Women may participate in sexual coercion within the context of same-sex relationships, or they may employ psychological manipulation or emotional pressure to achieve sex. Although sexual coercion in humans is complicated and multidimensional, some tactics may be utilized to avoid and address this conduct. These include advocating for gender equality and respectful relationships, educating people about healthy sexuality and consent, and raising awareness about the incidence and consequences of sexual coercion.

Sexual Coercions in Non-Human Animals

Sexual compulsion manifests as hostile conduct towards possible mating partners in many animal species. Male elephant seals, for example, engage in brutal physical combat to assert dominance and obtain mating opportunities with females. Male baboons may also employ physical aggressiveness or intimidation to keep females from mating with other males. This conduct is assumed to increase the male's chances of passing on his genes by ensuring his mate bears his progeny.

Mate Guarding in Non-Humans

Mate guarding is another form of sexual compulsion in nonhumans. Males use physical aggressiveness, vocalizations, or other forms of intimidation to deter females from mating with other males. Males in some species may even physically grasp the female during copulation to ensure that they are the only ones to mate with her. Males in some bird species may engage in forced copulation when they force themselves on females, often injuring or killing the female.

This tendency is assumed to result from sexual conflict, in which males profit by mating with several females, while females discriminate more in their partner selection. In insects, sexual coercion can take the form of traumatic insemination, in which males use their genitalia to penetrate females in non-reproductive areas, inflicting bodily pain and possible illness or death. This activity is thought to improve the male's chances of fertilizing the female's eggs and passing on his genes.

Species Difference in Non-Humans

The prevalence and nature of sexual compulsion vary significantly between species. Some primates, for example, use more violent sexual compulsion than others, and some insect species use traumatic insemination while others do not. Factors that contribute to sexual coercion in nonhumans can be complicated and numerous as well.

For example, some species may be more susceptible to sexual coercion due to social dynamics or environmental factors, while others may have developed non-coercive mating methods. It is important to note that while sexual coercion is common among nonhuman animals, it is not present in all species. In some species, males and females have developed cooperative mating strategies that do not involve coercion or violence.

Implications of Sexual Coercion

Sexual coercion in nonhumans can be explained by the opposing reproductive interests of males and females, according to evolutionary psychology. Males may gain from mating with several partners to maximize their chances of passing on their genes, while females may be pickier in their mate selection to ensure their offspring's survival and well-being.

Understanding the motivations and techniques of sexual coercion in nonhumans can help us understand the evolution of sexual behavior and the elements that contribute to sexual coercion in humans. However, it is critical to proceed with caution when studying sexual compulsion in nonhumans and to examine the ethical implications of our findings and interpretations.

Furthermore, while sexual compulsion in nonhumans may be a natural habit, it can also have detrimental implications for the individuals involved. Forced copulation or traumatic insemination, for example, can inflict physical harm or even death on the female. At the same time, mate-guarding conduct can cause stress or injury to both males and females. It is consequently critical to investigate and comprehend sexual coercion in nonhumans to devise measures to reduce its prevalence and impact.


Sexual coercion is a complex and controversial topic in evolutionary psychology, with implications for humans and non-human animals. While the motivations and consequences of sexual coercion may differ across species, it is clear that biological, social, and environmental factors influence this behavior.

Further research is needed to understand better the factors that contribute to sexual coercion in both humans and non-human animals and to develop effective strategies for preventing and addressing this behavior.
