Prenatal Progesterone Affects Sexual Orientation
Prenatal sex hormones influence the development of physical and behavioral sex differences in animals and humans. A study published in Archives of Sexual Behavior suggests that prenatal administration of exogenous progesterone may influence sexual orientation later in life.
Hormone levels may affect the development of sexual orientation, although evidence is based largely on animal models or small-scale human studies without adequate controls. One theory, the prenatal theory of sexual orientation, suggests that the development of homosexuality is linked to hormonal disruptions in the womb. According to this theory, the level of androgen exposure in utero influences the development of homosexuality; in males, insufficient androgen exposure is linked to homosexuality, while homosexuality in females is said to result from excess exposure to androgen.
Progesterone has anti-androgenic and anti-estrogenic effects, and it is commonly prescribed during early and late pregnancy to address various concerns. The potential effect o
Homosexuality may help us bond, experts say
The results of a preliminary study provide the first evidence that our need to bond with others increases our openness to engaging in homosexual behavior.
Dr Diana Fleischman, of the University of Portsmouth, and colleagues examined the relationship between progesterone and sexual attitudes to explore the role that homosexual behavior may have played in cementing alliances over the course of human evolution.
Their research is published in the journal Archives of Sexual Behavior.
They found that heterosexual women who have higher levels of progesterone are more likely to be open to the thought of engaging in sexual behavior with other women. Similarly, when heterosexual men are subtly reminded of the importance of having male friends and allies, they report more positive attitudes toward engaging in sexual behavior with other men. This pattern is particularly dramatic in men who have high levels of progesterone.
The hormone progesterone is known to contribute to the formation of social bonds, which have many adaptive benefits for huma
