Gynecological concerns in young and adolescent physically active girls.
Young girls should be advised to develop the regular exercise habit and to maintain it throughout life. Prepubertal athletes are more likely than their sedentary friends to experience menarcheal delay. Postmenarcheal athletes have increased susceptibility to oligomenorrhea and amenorrhea. Athletes with delayed puberty deserve examination and possibly further evaluation. Adolescent athletes with oligomenorrhea or amenorrhea deserve examination and hormonal evaluation. Hormonal replacement therapy is unnecessary prior to age 16, is optional between ages 16 and 18, and is recommended after age 18.
