Amenorrhea not due to pregnancy, lactation, or menopause is a relatively common abnormality of the reproductive years and indicative of a defect somewhere in the hypothalamic-pituitary-ovarian-uterine axis. It is due to a disruption of the normal cyclical pattern of endometrial stimulation by hormones and is usually associated with anovulatory menstrual cycles.
