About gynecologic care for infants and children

Children are generally cared for by their pediatrician or family physician; however, your pediatrician may contact a pediatric gynecologist to assist with difficult or challenging medical conditions. Common reasons children are seen by pediatric gynecologists include vulvar and vagina irritation that will not improve despite hygiene and medications, congenital anomalies of the genitalia, labial adhesions, lichen sclerosus, pelvic masses, and early signs of puberty (breast development) or vaginal bleeding.
