Endometriosis is a common condition, affecting 1 in 10 women of reproductive age, or approximately one million women in Canada. Endometriosis occurs when tissue from inside the womb grows outside of the womb, such as in different areas of the pelvis. Half of women with endometriosis experience sexual pain, which is felt as pelvic pain with deep penetration during sexual activity.
Sexual pain in endometriosis can occur when the endometriosis cells show invasive qualities. We recently identified non-inherited gene mutations in this type of invasive endometriosis.
