Local perineal implants of anti-androgen block masculinization of the spinal nucleus of the bulbocavernosus.

R B Fishman1, S M Breedlove.   

Abstract

Female rats were injected with testosterone propionate on the 1st and 3rd days of life. In addition, some females received 200 micrograms of the anti-androgen, hydroxyflutamide. Females receiving anti-androgen directly to the perineum, including the muscles bulbocavernosus and levator ani, had fewer surviving spinal nucleus of the bulbocavernosus (SNB) motoneurons than did females receiving the anti-androgen systemically. These results indicate that androgen acts upon the target muscles to spare developing SNB motoneurons from death.
