Endometriosis is a condition in which tissue similar to the uterine lining is found outside of the uterine cavity. Endometriosis may cause debilitating symptoms such as dysmenorrhea (menstrual pain), non-menstrual pelvic pain, and dyspareunia (painful intercourse).

Endometriosis lesions can be found throughout the pelvis and abdomen, including on the ovaries and intestines. It is unknown what determines the location of endometriosis.

How common is this? Is this normal? Abnormal?

Approximately 10% of women of reproductive age have endometriosis. Many of these women have symptoms that do not respond to hormonal contraceptives, the first-line therapy.

Women with suspected endometriosis can be identified prior to surgery using non-invasive tools including a combination of patient interviews, clinical examination, and imaging.

It is common for women to experience some discomfort during their menstrual cycles. Moderate-to-severe pain that disrupts daily activities is not normal. Uncertainty around what is normal and abnormal pelvic pain can contribute to delayed diagnosis.

How does endometriosis affect the body?

Many women with endometriosis experience menstrual pain, non-menstrual pelvic pain, and painful intercourse. A common association with endometriosis is infertility. Other effects of endometriosis, which can impact many organs, include fatigue and urinary and bowel symptoms. Estrogen, which is produced by the ovaries, contributes to the development and growth of endometriosis.

Standard treatment options

Standard treatment options for endometriosis include medical therapies and surgery. Some women report improved hormonal contraceptives improve their symptoms. GnRH agonists are injections that lower estrogen and manage the disease. This treatment is for short-term use due to bone mineral density loss, hot flashes, and other side effects from a low-estrogen state.

Laparoscopy is a surgical procedure that may include the removal of visible endometriosis. While some women report improved symptoms with hysterectomy, the surgery does not remove all endometriosis and involves removal of the entire uterus, which leads to the loss of fertility. Despite multiple laparoscopies, some women still undergo a hysterectomy, which can involve major complications such as excessive bleeding and infection. Additional treatment options exist. All treatment decisions should be discussed with a healthcare provider.

Turning science into medicine

Too often, endometriosis is dismissed as a “bad period” or normal menstruation. At Myovant, we believe that women should be empowered to lead full, healthy lives. This is why we are invested in driving women’s health forward and developing innovative treatments to improve the current standard of care.
