title: [Progress in research on the biological reason of male homosexuality].
abstract: Male homosexuality is a complex phenomenon which is universal and with unknown causes. Researchers believe that both biological and environmental factors have played a role in its pathogenesis. Researches focusing on genetics, neurobiology, development and endocrinology have made certain progress. In this paper, we have reviewed the biological causes of male homosexuality, which may provide clues for further research in this field.
