title: Androsterone-etiocholanolone ratios in male homosexuals.
abstract: Analyses of 24-hour specimens of urine from healthy adult males for androsterone and etiocholanolone produced values which, when calculated as discriminant scores, discriminated between heterosexual and exclusively homosexual individuals. This confirms a previous study.No significant differences were found between heterosexuals and homosexuals in parental ages, secondary sex characteristics, genitalia, anthropometry, 17-ketosteroids, and 17-ketogenic steroids.A significant difference was found between the heterosexual group and homosexual group in the number of homosexual relatives in the immediate and extended families.
