Endometriosis is a very frequent and debilitating disease responsible for a considerable socio-economic toll. In spite of that, its pathogenesis remains enigmatic. Endometriosis is hold for a multifactorial pathology resulting from the mixe…

Endometriosis and infertility are associated clinically. Medical and surgical treatments for endometriosis have different effects on a woman's chances of conception, either spontaneously or via assisted reproductive technologies (ART). Medi…

Endometriosis is an enigmatic disease of unknown etiology and pathogenesis, which is defined as the presence of endometrial glands and stroma outside the uterus. The most widely accepted theory to explain endometriosis is probably the trans…

OBJECTIVES: To evaluate the expression of five members of the neurotrophins family in ovarian endometriotic cyst (endometrioma) (OMA), compared to eutopic endometrium (EE) and to examine the correlation between the levels of induction and t…

Introduction: Endometriosis, defined as the growth of endometrial tissue outside \nthe uterine cavity is a common gynaecological disorder affecting 10-15% \nof women in their reproductive years. It is a major clinical problem causing in- \n…

Endometriosis affects 6-10% of women in their reproductive years, causing chronic pelvic pain and infertility. Its pathogenesis remains poorly understood and current treatments, based on hormonal therapy or surgery, are often insufficient. …

OBJECTIVE: To investigate whether the clinical history, particularly of the adolescence period, contains markers of deeply infiltrating endometriosis (DIE). DESIGN: Cross-sectional study. SETTING: Universitary tertiary referral center. P…

Several lines of evidence indicate that endometriosis could be partially due to selective epigenetic deregulations. Promoter hypermethylation of some key genes, such as progesterone receptor and aromatase, has been associated with the silen…

OBJECTIVE: To evaluate the rate of intrinsic ureteral endometriosis in patients presenting with severe ureteral endometriosis. DESIGN: Observational study between June 1992 and December 2007. SETTING: University tertiary referral center. …

Smoking habits did not influence either the risk of any form of endometriosis (superficial peritoneal endometriosis, ovarian endometriomas, and deep infiltrating endometriosis) and did not correlate with the revised American Fertility Socie…

Steroidogenic factor-1 (SF-1), a major protein regulating the complex cascade of steroidogenis, has been postulated to play a role in ovarian endometriosis. However, the expression in situ of SF-1 in ovarian endometriosis is unknown. To she…

BACKGROUND: Deep infiltrating endometriosis (DIE) is presented as a disease with high recurrence risk. Bladder DIE is the most frequent location in cases of urinary endometriosis. Surgical removal has been recommended for bladder DIE but lo…

OBJECTIVE: This study analyzed the relationship between clinical characteristics of endometriosis and Th1/Th2 immune response patterns. METHODS: A prospective study was performed with 65 patients with endometriosis (Group A) and 33 without…

In women with endometriosis, including those with endometriomas, 6 to 8 weeks of continuous use of oral contraception (OC) before assisted reproduction treatment (ART) maintains ART outcomes comparable with the outcomes of age-matched contr…

The aim of the present study, involving 463 women of reproductive age, was to evaluate for the first time the relationship between endometriosis, endometriosis-related infertility, and a recently described functional polymorphism in the ALO…

OBJECTIVE: To analyze the expression of estrogen (ER) and progesterone (PR) receptors in the smooth muscle component (SMC) of deep infiltrating endometriosis (DIE). DESIGN: A prospective clinical and pathologic study of 60 cases of DIE. S…
