Endometriosis is a chronic disease characterized by the ectopic presence of endometrial cells that evade apoptosis and survive and proliferate under harsh environmental conditions. It is closely associated with infertility and pregnancy-rel…

AIM: Endometriosis is a chronic gynecological condition characterized by persistent inflammation and frequently associated with dysmenorrhea and infertility. The success rate of assisted reproductive technology (ART) in individuals with end…

BACKGROUND: Endometriosis is a chronic inflammatory disorder that affects approximately 10% of women of reproductive age and exhibits tumor-like characteristics such as invasion, recurrence, and hormone-dependent proliferation despite its b…

Background: Endometriosis is a common gynecological condition, with symptoms including pain and infertility. Regurgitated endometrial cells into the peritoneal cavity encounter hypoxia and nutrient starvation. Endometriotic cells have evolv…

BACKGROUND: Numerous efforts have been undertaken to identify biomarkers associated with embryo and oocyte quality to improve the success rate of in vitro fertilization. Metabolomics has gained traction for its ability to detect dynamic bio…

AIM: The increasing incidence of cesarean sections has led to a higher prevalence of cesarean scar defects (CSDs), predominantly characterized by postmenstrual bleeding in affected women. CSD manifests in various forms, including isolated m…

AIM: Endometriosis is a complex, multifactorial disease. Recent advances in molecular biology underscore that somatic mutations within the epithelial component of the normal endometrium, alongside aberrant epigenetic alterations within endo…

It is considered that the etiology of endometriosis is retrograde menstruation of endometrial tissue. Although shed endometrial cells are constantly exposed to a challenging environment with iron overload, oxidative stress and hypoxia, a fe…

BACKGROUND: To date, the development of therapy for endometriosis and disease-related infertility remains a major challenge. Iron overload caused by periodic bleeding is a hallmark of endometriosis. Ferroptosis is an iron- and lipid-reactiv…

AIM: Endometriosis is a chronic disease of reproductive age, associated with pelvic pain and infertility. Endometriotic cells adapt to changing environments such as oxidative stress and hypoxia in order to survive. However, the underlying m…

Hemoglobin concentrations in endometriotic cyst fluids have been found to be associated with distinct clinical manifestations, such as pelvic pain and infertility, as well as with malignant transformation. However, the measurement of the he…

Background: Endometriosis is an estrogen-dependent disease and causes pelvic pain and infertility. The limits of current pharmacotherapy in women who desire to become pregnant prompt the development of various targeted molecules for more ef…

PURPOSE: The study aims to identify the clinicopathological risk factors and magnetic resonance (MR) imaging findings for adenomyosis-related symptoms, including menorrhagia, dysmenorrhea, and infertility. METHODS: This was an observation-b…

BACKGROUND: The aim of this study is to investigate the clinicopathological features of intrinsic and extrinsic subtypes in adenomyosis. In particular, we focused on the early lesions of adenomyosis. METHODS: This is a single-center, prospe…

OBJECTIVES: The balance between oxidative stress and antioxidant defense has been reported to differ between women with endometriosis and patients with its malignant transformation. The aim of this study is to investigate changes in redox b…

Ovarian function suppression is the current pharmacotherapy of endometriosis with limited benefit and adverse effects. New therapeutic strategies other than hormonal therapy are developed based on the molecular mechanisms involved in the hy…

The aim of this review is to investigate the oxidant/antioxidant status and its regulatory mechanisms in patients with endometriosis and to summarize the antioxidant therapy as an alternative to hormonal therapy for endometriosis. Each keyw…

AIMS: The most common symptoms of adenomyosis include heavy menstrual bleeding and dysmenorrhea. A variety of medical or surgical techniques are utilized for the treatment of adenomyosis, but there are currently no specific treatment guidel…

OBJECTIVES AND DESIGN: Endometriosis-related pain can be caused by anatomical distortions as well as environmental factors such as inflammation and oxidative stress. The aim of this study is to investigate the relationship between the sever…

AIMS: The purpose of this study is to first investigate the correlation between image features and histological findings and the clinical severity of adenomyosis; second, search for imaging features to assess the type and locoregional exten…

Endometriosis is an estrogen-dependent gynecologic disease. Endometriotic cells survive in oxidative stress and hypoxic environments. The aim of this review is to reconsider new therapeutic strategies for endometriosis by focusing on estrog…

OBJECTIVES: Magnetic resonance (MR) R2 relaxometry is a safe, noninvasive diagnostic modality for the evaluation of iron levels in the contents of ovarian cysts. The study aims to investigate the sensitivity and specificity of the two metho…
