Effect of castration on male laryngeal muscle fiber number. In each experiment (A,B,C), values obtained from gonadectomized males (middle bar) are compared to two controls: intact males at the stage that experimental males were castrated (bar at far left) and intact males at the stage that fibers in experimental males were counted (bar at far right). (A) Males were castrated at PM0 and fibers were counted at PM2. (B) Males were castrated and flutamide treated at PM0 and fibers were counted at PM2. (C) Males were castrated at PM2 and fibers were counted at PM6. Asterisks indicate significant differences (P≤0.05) between adjacent groups.
