What Is Amenorrhea?
Amenorrhea is the absence of menstrual bleeding and may be primary or secondary.
For a woman to have regular menstrual cycles, her hypothalamus, pituitary gland, ovaries, and uterus should all be functioning normally. The hypothalamus stimulates the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH). FSH and LH cause the ovaries to produce the hormones estrogen and progesterone. Estrogen and progesterone are responsible for the cyclical changes in the endometrium (uterine lining), including menstruation. In addition, a woman’s genital tract should be free of any abnormalities to allow the passage of menstrual blood.
