Key facts

Endometriosis is caused by tissue that usually lines inside the uterus developing outside the uterus. It is a chronic and complex disorder, affecting 10% of all women of reproductive age, and up to 40% of all women with infertility, representing an estimated 180 million patients worldwide.

Endometriosis affects 10% of all women of reproductive age

Patients with endometriosis present with a variety of symptoms, most notably chronic pelvic pain (75% of patients) and infertility (up to 40%). Common signs of endometriosis include painful menstrual cramps, pain during or after sexual intercourse, pain in the intestine or lower abdomen, painful urination, heavy menstrual periods, bleeding between periods, painful bladder syndrome, and chronic fatigue.

Severe but non-specific symptoms

Since symptoms are not specific and may be signs of other conditions, endometriosis is often misdiagnosed or remains undiagnosed for a long period of time. It has been estimated that it takes in average 7 to 11 years between the disease onset and its diagnosis. Currently, surgery is the only fully reliable method to detect the disease.

Major diagnostic delays

There's no permanent cure for endometriosis so far. Symptom relief is the primary goal of existing treatment options combining surgery and hormonal therapies. Even in the presence of effectively managed endometriosis, symptoms may recur since the root cause of the disease has not been treated.
