Two thirds of women with pelvic endometriosis experience chronic pelvic pain (CPP), dysmenorrhea, dyspareunia, dysuria, dyschezia and pain in musculoskeletal regions such as the thighs and lower back [1]. Due to the stress caused by infertility and pain, endometriosis interferes with quality of life by negatively impacting social, sexual and professional aspects. The disease is reported to be associated with depression, anxiety, high trait anxiety and high levels of stress. This section explores the effects of endometriosis and treatment on quality of life.

The Derogatis Sexual Functioning Inventory is composed of 254 items and ten subtests: Information, Experience, Drive, Attitude, Symptoms, Affect, Gender Role, Fantasy, and Sexual Satisfaction subtests [2]. The 10-item sexual satisfaction subtest served as the basis for the 14-item sexual functioning questionnaire used by Ferrero et al. [3]. Some studies have reported the global sexual satisfaction Index scores of endometriosis patients. This Index is a global measure of the Derogatis Sexual Functioning Inventory. The global sexual satisfaction index represents quality of sex life on a nine-point scale from 0 (could not be worse) to 8 (could not be better) [4].
