    Progestin for Endometriosis



    How Well It Works

    Like all hormone therapies and surgery, progestin does not cure endometriosis.

    Progestin may improve symptoms of endometriosis, such as pain during periods and pelvic pain. When compared with other hormone therapies, it has proved to be equally effective. Generally about 80% to 90% of women gain relief with any particular hormone therapy.Reference 1

    Pain recurrence

    After GnRH-a treatment, or any other hormone therapy, endometriosis pain can return.Reference 1

    • Each year, up to 20% of all women treated will have pain return after hormone treatment.
    • About 37% of women who use hormone therapy for mild endometriosis have pain 5 years later.
    • About 74% of women who use hormone therapy for severe endometriosis have pain 5 years later.
