This document discusses adolescent gynecology issues including abnormal menstruation such as precocious puberty or delayed menarche, pathology associated with low estrogen states, and genital trauma including sexual abuse. Precocious puberty is defined as breast and pubic hair growth before age 8 or menstruation before age 10, which can be caused by premature gonadotropin release from the anterior pituitary or feminizing ovarian tumors. Treatment depends on the underlying cause and may involve GnRH analogs, surgery, or treating an intracranial lesion. Pathology from hypoestrogenism can cause labial adhesions.
