[Etiopathogenesis of true male homosexuality (androgenic insufficiency?)].

Clinical and experimental studies have suggested the author the possibility that an androgenic insufficiency, during embryogenesis or the perinatal period, may be a determinant factor in the pathogenesis of the anomalies of homosexual behavior. In the author's opinion, the androgenic anomalies seen in the genuine male homosexual have no pathogenic significance, but are a repetition of what occured during embryogenesis of the perinatal period, at the time when these anomalies had a pathogenic role.
