Anatomy comparison of male and female as they grow up

THE SECONDARY SEXUAL CHARACTERISTICS

The Female

Females experience the physical changes of puberty in the following order: First, the breasts begin to enlarge. Then some straight and later kinky or curly hair appears on the vulva. This pubic hair forms a triangle pointing downward. Eventually, some hair will also appear in the armpits (railed axillary hair). During this time, the body grows in height, and the hips become wider than the shoulders. Fatty tissue in and around the breasts, shoulders, hips, and buttocks gives the female body its generally rounder appearance. The first menstruation (also known as menarche) indicates approaching sexual maturity. In the beginning, the menstrual cycles are still irregular, and in some of them there may be no ovulation. In other words, for a while a girl may menstruate and still be largely infertile. Indeed, a woman usually gains her full reproductive capacity only one or two years after her first menstruation.
In females, there is no decisive enlargement of the larynx and therefore no voice change comparable to the one taking place in males. In general, women are also less muscular and slightly shorter than men. At the end of puberty, the breasts have developed their typica! rounded shape and thus become the most obvious female secondary sexual characteristic. However, they do not produce milk until after pregnancy.
