Investigation has also demonstrated that evolutionary adaptations of testis dimension are dependent on the breeding method in which the species resides.[45] One-male breeding methods—or monogamous societies—are likely to display lesser testis sizing than do multi-male breeding systems or additional-pair copulation (EPC) societies. Human males Stay largely in monogamous societies like gorillas, and therefore testis dimensions is lesser in comparison to primates in multi-male breeding methods, for example chimpanzees.
