Amenorrhea describes the absence of a period, also called menstruation, in a woman of reproductive age. Primary amenorrhea consists of the absence of the occurrence of the first menstruations in a girl who has passed the age of puberty. It can be due to delayed puberty, a malformation of the vagina or the uterus, an endocrine or hormonal anomaly, or a genetic illness such as Turner's syndrome. The treatment is adapted to the cause of amenorrhea: medication, hormones, or surgery.
