Values are given as means±S.D.

Single numbers indicate that body weight was only available for one animal within the group.

^*Slashes represent stage treatment begun/stage fibers counted. FL=flutamide. TP=testosterone propionate 0+ and 2+ represent animals grown for five weeks starting from PM0 and PM2, respectively. =castrated male: =ovariectomized female.
