ANNICCHIARICO, IVÁN. Psychobiology of Male Homosexuality: Recent Findings. Univ. Psychol. [online]. 2009, vol.8, n.2, pp.429-446. ISSN 1657-9267.

In this paper, empirical and theoretical reports which question the causes of male homosexuality are examined. According to these reports, male homosexuality differs from female homosexuality in some respects. Additionally, evidence favouring the consideration of male homosexuality as a biological condition is shown: there are brain differences between gay men and heterosexual men, there are genetic and perinatal factors associated to male homosexuality, there are cognitive and behavioral differences between gay and heterosexual men, there are animal models for studying homosexuality; finally, there are negative findings concerning the psychosocial factors associated to male homosexuality.

Keywords : Male Homosexuality; Genetic Factors; Perinatal Androgenization; Behavioral Traits; Psychobiology; Cognition; Homosexuality; Male - Genetics; Virilism; Sexual Behavior - Psychology.
