Endometriosis is a condition characterized by ectopic endometrial tissues located outside of the uterus, most commonly found on the pelvic peritoneum or ovary. Endometriosis, which occurs in 7-10% of women in the general population and 71-87% of women with chronic pelvic pain, is associated with dysmenorrhea, chronic pelvic pain, and infertility. There is considerable debate about the effective...

OBJECTIVES The identification of epidemiological factors increasing the risk of endometriosis could shorten the time to diagnosis. Specific blood groups may be more common in patients with endometriosis. STUDY DESIGN We designed a cross-sectional study of 633 Caucasian women living in the same geographic area. Study group included 311 patients with histologically proven endometriosis. Control...

BACKGROUND Endometriosis is a clinical condition that affects up to 10% of the women of reproductive age. Endometriosis is characterized by the presence of endometrial tissues outside the uterine cavity and can lead to chronic pelvic pain, infertility and, in some cases, to ovarian cancer. METHODS In order to better understand the pathogenesis of endometriosis, we have used Serial Analysis of...

BACKGROUND AND OBJECTIVES The identification of highstage and recurrent cases of bowel endometriosis is critical, because these cases require careful surgical planning. We aim to describe the clinical characteristics of women with bowel endometriosis, our principles in laparoscopic management of this pathology, and to identify predictors of severe disease and recurrence. METHODS This was a r...

The aim of the present review was to illustrate how dysregulation of hormonal signaling regulates expressional changes of spatially associated genes in endometriosis. From a multi‑platform endometriosis dataset, an integrated analysis was performed of epigenomic changes of several biologically relevant genes that have been validated in the literature. Estrogen receptor (ER) may act as a direct ...

BACKGROUND The objective of the present study was to expand our understanding of the role of matrix metalloproteinase-7 (MMP-7) in the pathophysiology of endometriosis. METHODS Expression levels of MMP-7 mRNA and protein in the eutopic endometrium and ectopic endometrium of patients with different forms of endometriosis were measured with immunohistochemistry and real-time RT-PCR. Endometrial...

OBJECTIVE To examine the effect of peritoneal fluid (PF) of patients with endometriosis on the cytoskeleton of metaphase II oocytes and correlate the results with the stage of endometriosis and the duration of infertility. DESIGN Prospective-controlled study. SETTING Center for reproductive medicine at a tertiary-care hospital. PATIENT(S) Women with endometriosis (n=23) and tubal ligation...

CONTEXT AND OBJECTIVE One of the diagnostic markers of endometriosis is CA-125, and elevated levels of this are caused by high concentrations in the ectopic endometrium. The objective of this study was to correlate CA-125 levels in serum and peritoneal fluid from women with and without pelvic endometriosis. DESIGN AND SETTING This was a prospective, cross-sectional, controlled study of consec...
