metoidioplasty 99
Testosterone replacement therapy gradually enlarges the clitoris to an average size of 4–5 cm (1.6–2 in) (as the clitoris and the penis are developmentally homologous). In a metoidioplasty, a surgeon separates the enlarged clitoris from the labia minora, and severs its suspensory ligament in order to lower it to the approximate position of the penis.
