BACKGROUND: Adenomyosis is a benign uterine disease that has been associated with endometrial proliferative disorders. Adenomyosis and endometrial cancer (EC) are sex-steroid-dependent conditions that may coexist, but their estrogen recepto…

Patients with endometriosis report increased levels of perceived stress, which correlates with disease severity and pain intensity, creating feedback loops that perpetuate the cycle of endometriosis inflammation, chronic pain syndrome, and …

• EMT-related markers show marked heterogeneity across endometriotic lesions • Distinct epithelial, mesenchymal-enriched, and mixed phenotypic patterns were identified • E-cadherin, N-cadherin, and vimentin display variable expression at th…

OBJECTIVES: The aim of this study was to investigate the clinical characteristics of women with superficial peritoneal endometriosis (SUP) diagnosed by surgery and not confirmed by histology, compared with histologically proven SUP. DESIGN…

Abnormal uterine bleeding (AUB) is a bleeding from the uterine corpus that is abnormal in regularity, volume, frequency or duration. It encompasses heavy menstrual bleeding, irregular menstrual bleeding and intermenstrual bleeding, which ar…

• Endometriosis is fueled by local estradiol accumulation that might be due to deficient HSD17B2 activity. • The microRNAs miR-124-3p and miR-26b-5p target the HSD17B2 gene. • This study measured miR-124-3p and miR-26b-5p in endometriotic l…

The limitations of current imaging methods to detect small or superficial endometriotic lesions prompt the search for new molecular targets. TSPO is an 18 KDa protein located in the outer mitochondrial membrane, which can be traced by posit…

Endometriosis is a condition characterized by increased oxidative stress and chronic inflammation, which can be treated with progestins and other progesterone receptor ligands. However, some patients are refractory to this treatment and the…

Consequences of the shift from the use of non-invasive testing for diagnosis to screening purposes • As the high-throughput screening and sequencing become increasingly faster and affordable, that there will be a swell of commercial non-inv…

Hashimoto thyroiditis is an autoimmune disease characterized by hypothyroidism and a high level of anti-thyroid autoantibodies. It has shown to negatively impact female fertility; however, the mechanisms are unclear. Ovarian follicular flui…

Endometriosis, an inflammatory-hormonal chronic disease, has a strong impact on women's quality of life, and fertility; however, after decades of intensive investigation, the complex events underlying its development and progression remain …

BACKGROUND: Inhibins and their co-receptor betaglycan are members of the transforming growth factor β superfamily, a group of signaling molecules that control the differentiation of human endometrium in the secretory phase of the menstrual …

Abstract Study question Is TSPO expressed in endometriotic lesions and negative in adjacent tissues, being eligible as a molecular target for noninvasive detection of endometriosis? Summary answer TSPO is detected in endometriotic lesions a…

Endometriosis is a chronic inflammatory disease affecting 10% of women in reproductive age and manifested as infertility and pelvic pain, which may be severe and incapacitating. This review aims to address the latest evidence on the associa…

BACKGROUND: Human endometrium harbors stem/progenitor cells (SPCs) that may contribute to the establishment of endometriosis when seeded outside the uterus. Oct-4, C-kit and Musashi-1 are some of the many proteins used to characterize SPCs,…

In recent years, there has been an increasing interest in natural therapies to prevent or treat female diseases. In particular, many studies have focused on searching natural compounds with less side effects than standard hormonal therapies…

OBJECTIVE: Angiotensin-converting-enzyme 2 (ACE2), the cell surface receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is found in a variety of reproductive tissues. The present study evaluated whether uterine fibroi…

Clinical studies clearly indicate that endometriosis is a condition associated with high levels of chronic stress. The stress intensity correlates with pain severity and disease extension. However, it is unknown whether chronic stress repre…

RESEARCH QUESTION: How effective is medical hormonal treatment in preventing endometriosis recurrence and in improving women's clinical symptoms and quality of life? DESIGN: This observational cross-sectional study evaluated the effects of…

BACKGROUND: Despite intense research, it remains intriguing why hormonal therapies in general and progestins in particular sometimes fail in endometriosis. OBJECTIVE AND RATIONALE: We review here the action mechanisms of progesterone recep…

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…

STUDY QUESTION: What are the effects of B lymphocyte inactivation or depletion on the progression of endometriosis? SUMMARY ANSWER: Skewing activated B cells toward regulatory B cells (Bregs) by Bruton's tyrosine kinase (Btk) inhibition us…

Endometriosis is a benign gynecological disorder which presents significant challenges in terms of diagnosis and management. Despite decades of research, there are no sufficiently sensitive and specific signs and symptoms nor blood tests fo…
