Under the influence of androgens, the change in voice pitch that occurs in adolescent males is because of a growth spurt in the larynx. The growth of the larynx is more evident in boys, leading to a drop in the male voice of about one octave. The larger vocal folds of males are probably responsible for them having a lower fundamental frequency. Typically, the voice change in boys takes place before the appearance of noticeable facial hair by months and even sometimes years.<\/p>\n
