1. Normal Pubertal Development Similar to girls, boys demonstrate an upward inflection in the slope of stature at the beginning of their growth spurt, followed by a more rapid increase in stature... |
...
but the peak height velocity occurs about 2 years later than for girls,
around 14 years of age. |
|
|
unlike
females, males can continue to grow to the end of the stature curves at
age 20, although the increment in stature after age 18 is usually not more
than 1 cm. |
|
| The increase in stature in males is due to androgens produced by the testes, so the growth spurt in stature is preceded by an increase in the size of the testes. These same androgens also cause the penis to lengthen and widen. |
