Effect of 5 weeks testosterone treatment on male and female laryngeal tension and fiber recruitment at PM2. Testosterone treated groups can be compared with PM6 male values (column at far right) and untreated frogs of the same age and sex. The percentage of transient tension is fully masculinized by testosterone treatment in both sexes. EMG potentiation is only partially masculinized by testosterone treatment in both sexes. Asterisks indicate a significant difference between groups. NS indicates no significant difference between groups.
