There is robust evidence to the effect that homosexual individuals have systematically less offspring. The sexually antagonistic genes hypothesis claims that this fitness-related disadvantage of homosexual individuals is compensated by their other-sex relatives exhibiting greater fertility than the relatives of straight individuals.

This poster presents findings from a large-scale Czech study comparing well-being and self-esteem between gender-diverse populations and cisgender individuals within the cultural context of Eastern Europe. The study reveals that binary transgender and non-binary/genderqueer individuals report significantly lower life satisfaction and self-worth com...
The development of human sexual orientation remains a complex and multifaceted subject. It is often studied but its origins continue to elude us. In this preregistered study, our primary objective was to demonstrate the fraternal birth order effect (FBOE), which assumes a higher prevalence of older brothers in gay men than in their straight counter...
One proposal for the persistence of homosexuality in the human population is the sexually antagonistic gene hypothesis, which suggests that the lower fertility of homosexual individuals, especially men, may be compensated by higher fertility of their relatives of the opposite sex. To test this hypothesis, we have collected data from 7,312 heterosex...

The aim of this paper is to summarize theories that try to explain male homosexuality within the framework of evolution. Fur...
