Female secondary sex characteristics

Body changes in girls at puberty due in part to estrogens

enlargement of breasts, uterus, vagina due to estrogens - feminizing hormones and absence of testicular androgens

narrow shoulder, broad hips, diverging arms, female distribution of fat, high-pitched voice, less body hair, more scalp hair

growth of pubic and axillary hair due to adrenal cortex and ovarian (less) androgens

Puberty in Boys

Puberty may begin as early as age 9 and continue until age 16.

At puberty, the testes increase testosterone production.

Testosterone causes reproductive organs to mature, muscle and bone to grow, facial and pubic hair to appear, and the voice to deepen.
