control hormones, see
Birth Control Pills, Patch, or Ring.

therapy lowers estrogen, triggering a
menopause-like state. This shrinks implants and
reduces pain for most women.
Progestin (pills or Depo-Provera shot) stops
ovulation and lowers estrogen. For most women, it shrinks endometriosis growths and reduces
pain. Some studies show that the levonorgestrel intrauterine device (IUD) decreases pain.7
Danazol therapy lowers estrogen levels
androgen levels, triggering a menopause-like state.
This shrinks growths and reduces pain for most women. This
relief usually lasts for 6 to 12 months after treatment. But danazol side
effects can be significant.

cause side effects and pose certain health risks. Some cause especially
unpleasant side effects. Before starting a medicine or hormone therapy, review
its possible side effects. If they sound less difficult than your endometriosis
symptoms, discuss the therapy with your doctor.
