Overview

Amenorrhea, or amenorrhœa, is the absence of a menstrual period in a woman of reproductive age. Physiologic states of amenorrhoea are seen during pregnancy and lactation (breastfeeding), the latter also forming the basis of a form of contraception known as the lactational amenorrhea method. Outside of the reproductive years there is absence of menses during childhood and after menopause. Amenorrhea can be transient, intermittent, or permanent. Amenorrhoea is a symptom with many potential causes.
