Puberty is a sequence of events in which physical changes occur, resulting in adult physical characteristics and capacity to reproduce. These physical changes are regulated by changes in the levels of hormones that are produced by the pituitary gland—luteinizing hormone and follicle-stimulating hormone. At birth, levels of these hormones are high, but they decrease within a few months and remain low until puberty. Early in puberty, levels of luteinizing hormone and follicle-stimulating hormone increase, stimulating the production of sex hormones. The increased levels of sex hormones (primarily estrogen) result in physical changes, including maturation of the breasts, ovaries, uterus, and vagina. Normally, these changes occur sequentially during puberty, resulting in sexual maturity.
