The objective of this paper is to compare assisted reproductive technology (ART) cumulative live birth rates after hysteroscopic proximal tubal occlusion and laparoscopic salpingectomy in endometriosis patients, for management of hydrosalpi…

Diffuse adenomyosis, focal adenomyosis, ovarian endometrioma, superficial endometriosis and deep infiltrating adenomyosis are all defined by the presence of an endometrioid tissue in an ectopic location that is at distance from the endometr…

RESEARCH QUESTION: In women with radiologically diagnosed adenomyosis, is the presence of endometriosis associated with a higher rate of miscarriage? DESIGN: An observational cohort study of women who received medical care for benign gynae…

RESEARCH QUESTION: What prognostic factors relate to a high oocyte yield in fertility preservation for women affected by endometriosis? DESIGN: Observational cohort study conducted in a tertiary care university hospital between April 2015 …

This review aims at better understanding the genetics of endometriosis. Endometriosis is a frequent feminine disease, affecting up to 10% of women, and characterized by pain and infertility. In the most accepted hypothesis, endometriosis is…

Endometriosis and adenomyosis are two frequent diseases that impair women's quality of life by causing pain and infertility. Both endometriosis and adenomyosis are heterogeneous diseases that manifest as different forms. Adenomyosis may be …

The epithelial to mesenchymal transition (EMT) has been implicated in the development of adenomyosis, along with dysregulated immune responses. Inflammation potentially induces Notch signaling, which could promote this EMT. The objective of…

Endometriosis may exert a profound negative influence on the lives of individuals with the disorder, adversely affecting quality of life, participation in daily and social activities, physical and sexual functioning, relationships, educatio…

OBJECTIVE: To evaluate the assisted reproductive technology (ART) cumulative live-birth rate (LBR) in a cohort of bowel endometriosis patients with no prior history of surgery for endometriosis. DESIGN: Prospective cohort study. SETTING: …

Abstract Study question How to assess the different adenomyosis phenotype before and after pregnancy on magnetic resonance imaging according to stringent validated criteria ? Summary answer Diffuse adenomyosis increases significantly after …

Abstract Study question Does endometrioma (OMA) size affect the number of oocytes retrieved after ovarian stimulation (OS) in women with deep infiltrating endometriosis (DIE)? Summary answer: No significant difference in the number of oocyt…

Abstract Study question What is the impact of adenomyosis and its magnetic resonance imaging (MRI) characteristics on live birth rate (LBR) in endometriosis-affected women undergoing in-vitro fertilization (IVF) treatment? Summary answer Am…

Abstract Study question Does a previous history of surgery for ovarian endometriosis (OMA) has an impact on controlled ovarian stimulation (COS) response in case of fertility preservation (FP) for endometriosis? Summary answer After COS, a …

OBJECTIVE: To provide a snapshot of the surgical management of endometriosis in French high-volume activity centers. METHODS: Analysis of prospectively collected data between November 2015 and May 2017 in 21 centers with a high volume of e…

STUDY OBJECTIVE: To describe the surgical management and risks of postoperative complications of patients with urinary tract endometriosis in France in 2017. DESIGN: Multicenter retrospective cohort pilot study. SETTING: Departments of gy…

STUDY QUESTION: Do adenomyosis phenotypes such as external or internal adenomyosis, as diagnosed by MRI, have the same clinical characteristics? SUMMARY ANSWER: External adenomyosis was found more often in young and nulliparous women and w…

For patients with endometriosis-related infertility, the impact of previous surgery for endometriosis before assisted reproductive technology (ART) remains controversial, particularly in cases of deep infiltrating endometriosis (DE). To stu…

BACKGROUND: Adenomyosis is a benign uterine disorder where endometrial glands and stroma are pathologically demonstrated within the uterine myometrium. The pathogenesis involves sex steroid hormone abnormalities, inflammation, fibrosis and …

RESEARCH QUESTION: What is the correlation between serum metabolic profile and endometriosis phenotype? DESIGN: A pilot study nestled in a prospective cohort study at a university hospital, including 46 patients with painful endometriosis …

OBJECTIVE: To study the association between adenomyosis and infertility, according to the adenomyosis phenotype as diagnosed by magnetic resonance imaging (MRI). DESIGN: A single-center, cross-sectional study. SETTING: University hospital…

OBJECTIVE: To determine whether the presence of focal adenomyosis of the outer myometrium (FAOM) at preoperative magnetic resonance imaging is associated with the severity of deep infiltrating endometriosis. DESIGN: Observational cross-sec…

Endometriosis is a chronic hormono-dependent inflammatory gynecological disease. Endometriosis can be subdivided into three forms: superficial peritoneal implants, endometrioma, and deep infiltrating endometriosis (DIE). Inflammation is a t…
