Abstract
Treatment of newly born Poecilia sphenops (Cuvier & Valenciennes, 1846) with 50 mg 17α-methyl-testosterone or 200 mg androstenedione per kg diet for 30 days induced a maximum of 59% males; attempts to increase masculinization by increasing dose or treatment duration resulted in higher mortality. The growth of the treated males was significantly (25-53% retarded. Anabolic enhancement of relative growth (percentage of control) of the treated males and females was apparent in juveniles but not in adults. Hormonal induction of masculinization impaired the gonadal development and courtship activity, and led to the production of sterile males and females.
