Regarding the fact that gay men leave less offspring than straight men, it is appropriate to raise a question by which means is male homosexuality maintained in a population and what could eventually be its evolutionary role. The aim of this paper is to summarize theories that try to explain male homosexuality within the framework of evolution. Furthermore, it aims to critically evaluate the results of empirical research that support particular theories or give evidence against them. In the first part, the paper provides a review of knowledge about the genetic and immunological origins of male homosexuality which consequently serves as a theoretical base for the main part of the paper that pursues the five most influential evolutionary theories of male homosexuality.
