The presence of estrogen in a pubertal girl stimulates the formation of secondary sex characteristics, including development of breasts, production of cervical mucus, and vaginal cornification. As estrogen levels increase, menses begins and ovulation is maintained for several decades. Ovarian estrogen production late in puberty is at least in part responsible for termination of the pubertal growth spurt, thereby determining adult height. Decreasing levels of estrogen are associated with lower frequency of ovulation, eventually leading to menopause. Hair growth during puberty is caused by androgens from the adrenal gland and, later, the ovary.
