STUDY QUESTION: Are anti-Müllerian hormone (AMH) levels lower in women with endometriosis, notably those with endometriomas (OMAs) and deep infiltrating lesions, compared with controls without endometriosis? SUMMARY ANSWER: Endometriosis a…

Introduction: Endometriosis, histologically defined as the presence of endometrium-like tissue - glands and stroma - that develops outside of the uterine cavity, is still an enigmatic disease responsible for pelvic pain and infertility. The…

Cytokines, and specifically interleukin 6 (IL-6) and interleukin 8 (IL-8), have been associated with the pathogenesis of endometriosis. We studied serum concentrations of IL-6 and IL-8 in patients with deep infiltrating endometriosis (DIE) …

BACKGROUND: The objective of this study was to evaluate the significance of severe preoperative pain for patients presenting with ovarian endometrioma (OMA). METHODS: Three hundred consecutive patients with histologically proven OMA were e…

Recurrence of deep endometriosis remains a major issue in the management of endometriosis. The main cause for recurrence appears to be an incomplete excisional surgery. Therefore, the goal of the primary surgery should be the complete resec…

BACKGROUND: Interleukin 33 (IL-33) is a cytokine involved in fibrotic disorders. We have analyzed IL-33 levels in the sera and peritoneal fluids of women with various forms of endometriosis and investigated the correlation with disease acti…

OBJECTIVE: To investigate key genes expression of the sphingosine-1-phosphate pathway in endometriotic tissues. DESIGN: A case-control laboratory study. SETTING: Tertiary care university hospital. PATIENT(S): A total of 31 women, with (n…

BACKGROUND: An inverse association between BMI and endometriosis has been reported but remains controversial. We decided to evaluate the association between BMI and the different types of endometriosis, classified as superficial endometrios…

Glyceroneogenesis, a metabolic pathway that participates during lipolysis in the recycling of free fatty acids to triglycerides into adipocytes, contributes to the lipid-buffering function of adipose tissue. We investigated whether glyceron…

Endometriosis, a disease of young females that is possibly a devastating ailment requiring surgery, appears to be associated with certain features encountered in adolescence. First among these symptoms is the history of severe and lasting d…

BACKGROUND: The relationship between the use of oral contraception (OC) and endometriosis remains controversial. We therefore compared various characteristics of OC use and the surgical diagnosis of endometriosis histologically graded as su…

Deep infiltrating endometriosis (DIE) is a particular clinical and histological entity of endometriosis responsible for chronic pelvic pain and infertility. Here we characterize the proliferative phenotype of DIE cells, to explore the cellu…

Steroidogenic factor-1 (SF-1) protein expression was not observed in any form of endometriosis (peritoneal, ovarian, or deep infiltrating endometriosis), which suggests that SF-1 locally produced by endometrial or stromal cells may not play…

OBJECTIVE: To investigate the effects of antiproliferative drugs (anastrozole, methotrexate, and 5-fluorouracil [5-FU]) on the proliferation of endometriotic cells in vitro and in vivo. DESIGN: Ex vivo study on human endometrial and endome…

Deep infiltrating endometriosis (DIE) is characterized by chronic pain, hyperproliferation of endometriotic cells and fibrosis. Since cannabinoids are endowed with antiproliferative and antifibrotic properties, in addition to their psychoge…

OBJECTIVE: We conducted a prospective study to assess the long-term results of complete surgery for low rectal endometriosis (LRE), paying particular attention to surgical complications, functional results, and disease recurrence after a fo…
