Introduction Chronic pelvic pain (CPP) is one of the most frequent symptoms in women of reproductive age. This is an enigmatic clinical condition that results from the complex interactions of physiological and psychological factors with direct impact on the social, marital, and professional lives of women. Aim To evaluate the quality of life and sexual satisfaction of women who suffer from CPP with or without endometriosis. Method Forty-nine patients who had been diagnosed with endometriosis and 35 patients with CPP diagnosed with another gynecological condition, all 84 of whom were treated at the Chronic Pelvic Pain and Endometriosis Clinic at Universidade Federal de São Paulo (UNIFESP) from January to July of 2008. The controls were 50 healthy women from the Family Planning Clinic at UNIFESP. Main Outcome Measures World Health Organization Quality of Life Assessment-Bref (WHOQOL-BREF) quality of life questionnaire and the Golombok-Rust Inventory of Sexual Satisfaction (GRISS). Results No statistically significant differences were observed between the groups with CPP symptoms, in either the results from the WHOQOL-BREF or in the GRISS questionnaire. In both questionnaires, differences were observed when the two groups of symptomatic women were compared with the group of healthy women. Conclusion CPP caused by endometriosis or other gynecological conditions leads to a significant reduction of quality of life and sexual satisfaction.

Presently, little is understood about how endometriosis is established or maintained, or how genetic factors can predispose women to the disease. Because of the crucial role that the progesterone receptor polymorphism PROGINS plays in predisposing women to the development of endometriosis, we hypothesized that this variant may influence critical steps during endometrial cell metabolism that are involved in the pathogenesis of endometriosis. Eutopic endometria were collected from three sources: women with endometriosis who had a single PROGINS allele (from the progesterone receptor gene); women with endometriosis who had the wild-type progesterone receptor allele; and women without endometriosis who had the wild-type allele. Cells prepared from the eutopic endometria of these women were stimulated with both estradiol and progesterone, and then examined for cell proliferation, viability, and apoptosis.
