Sexual Development of Girls

For most girls, sexual maturation begins at about age 11, as fatty tissue accumulates around nipples, forming small “breast buds”.

Often pubic hair begins to appear later. About one-third of all girls develop some pubic hair before breasts begin to develop.

During adolescence, there may be a height spurt and breasts may grow rapidly. Sex organs begin to mature – internally the vagina becomes larger and the womb is stronger, externally the genitals also increase in size and become more sensitive to touch.

Often within a year, breasts and pubic hair will have fully developed and armpit hair is present.
