The aim of this study was to characterize a large sample of women with superficial peritoneal endometriosis (SUP) and no other types of endometriosis in order to test the association of SUP with gynecologic symptoms. We included 203 cases o…

OBJECTIVE: To investigate if there are any obvious clinical factors associated with delayed blastulation at day 6 (D6) compared with day 5 (D5). DESIGN: Monocentric observational cohort study from November 2012 to December 2018. SETTING: …

OBJECTIVE: To evaluate the association between the endometriosis phenotype and the age at menarche. DESIGN: An observational, cross-sectional study using prospectively collected data (Canadian Task Force classification II-2). SETTING: Singl…

BACKGROUND: Studies have shown a significant association between migraine and endometriosis, but no study has explored the relationship between migraine and endometriosis phenotypes: Superficial peritoneal endometriosis, ovarian endometriom…

Endometriosis is a chronic inflammatory disease defined as the presence of endometrial tissue outside the uterus, which causes pelvic pain and infertility. This disease should be viewed as a public health problem with a major effect on the …

Endometriosis and adenomyosis are histologically defined. The frequency of endometriosis cannot be precisely estimated in the general population. Endometriosis is considered a disease when it causes pain and/or infertility. Endometriosis is…

BACKGROUND: Many women whose fertility may have been impaired by endometriosis require assisted reproductive technology (ART) in order to become pregnant. However, the influence of ovarian endometriosis (OMA) on ovarian responsiveness to hy…

The pathophysiology of endometriosis is not completely understood, but an aberrant immune response in the peritoneal environment seems to be crucial for the proliferation of ectopic endometrial cells - as those cells escape apoptosis and pe…

OBJECTIVE: To study the prevalence of oligo-anovulation in women suffering from endometriosis compared to that of women without endometriosis. DESIGN: A single-center, cross-sectional study. SETTING: University hospital-based research cen…

STUDY QUESTION: Is endometriosis associated with aberrant sialylation patterns and what is the potential impact of such anomalies on cell migratory properties? SUMMARY ANSWER: The reduced α-2,6 sialylation patterns in the peritoneal fluid …

BACKGROUND: Controlled ovarian stimulation in assisted reproduction technology (ART) may alters endometrial receptivity by an advancement of endometrial development. Recently, technical improvements in vitrification make deferred frozen-tha…

BACKGROUND: Adenomyosis (ADE) is an enigmatic uterine disorder. Several types have been previously described: diffuse adenomyosis (DIF-ADE), focal adenomyosis (FOC-ADE), and association of focal and diffuse lesions (FOC/DIF-ADE). Abnormal i…

BACKGROUND: The 'Freeze all' strategy, which consists of cryopreservation of all embryos after the ovarian stimulation has undergone extensive development in the past decade. The time required for the endometrium to revert to a prestimulati…

The redox-sensitive nuclear factor erythroid-derived 2-like 2 (NRF2) controls endogenous antioxidant enzymes' transcription and protects against oxidative damage which is triggered by inflammation and known to favor progression of endometri…

Endometriosis is a benign chronic inflammatory disease, whose pathogenesis is still unclear. Endometriosis is responsible for infertility and/or pelvic pain. One of the most important features of the disease is the heterogeneity (clinical a…

Endometriosis is a chronic disease. The pathogenesis is actually still unclear. Endometriosis is responsible for infertility and/or pelvic pain. One of the most important features of the disease is the heterogeneity (clinical and anatomical…

Previously, we reported endometriotic-like decidual lesions in contact with the fetal membranes (FMs) in 11 pregnant women with severe endometriosis. In this report, an extensive histomorphological analysis was performed on the FMs of 19 pr…

STUDY QUESTION: What is the relationship between endometriosis phenotypes superficial peritoneal endometriosis (SUP), ovarian endometrioma (OMA), deep infiltrating endometriosis (DIE) and the adenomyosis appearance by magnetic resonance ima…

OBJECTIVE: To evaluate the impact of assisted reproduction technology (ART) on painful symptoms and quality of life (QoL) in women who have endometriosis as compared with disease-free women. DESIGN: Prospective controlled, observational co…

STUDY QUESTION: Is there an association between the endometriosis phenotype and presentation with infertility? SUMMARY ANSWER: In a population of operated patients with histologically proven endometriosis, ovarian endometrioma (OMA) per se…

STUDY QUESTION: Were spontaneous miscarriages more frequent in women with histologically proven endometriosis when compared with endometriosis-free controls? SUMMARY ANSWER: Endometriosis-affected women display a significantly higher rate …

BACKGROUND: Assisted reproductive technology is one of the therapeutic options offered for managing endometriosis-associated infertility. Yet, published data on assisted reproductive technology outcome in women affected by endometriosis are…

OBJECTIVE: Mitogen-activated protein kinases (MAPKs) are involved in the proliferation and survival of endometriotic lesions. Vemurafenib (PLX4032) is a novel protein kinase inhibitor that targets BRAF, a member of the MAPK pathway. The pre…

STUDY OBJECTIVE: To determine whether cancer antigen-125 (CA-125) levels are increased in women with endometriosis, especially in those with endometriomas (OMAs), deep infiltrating lesions (DIE), and superficial endometriosis (SUP) compared…

INTRODUCTION: Sorafenib is a strong multikinase inhibitor targeting 2 different pathways of endometriosis pathogenesis: RAF kinase and vascular endothelial growth factor receptor (VEGFR). We investigate whether Sorafenib could control the g…
