Stressful Events in Prenatal Life of Bi- and Homosexual Men

Abstract

One hundred bi- or homosexual men as well as 100 heterosexual men of similar age were asked about maternal stressful events that may have occurred during their prenatal life. A significantly increased incidence of prenatal stress was found in bisexual and, particularly, in homosexual men. This finding suggests that prenatal stress in males may represent a risk factor for the aetiogenesis of sexual deviations in later life.
