Gynecologic and obstetric investigation

OBJECTIVES: We aimed to determine the prevalence of female infertility in 204 countries and territories from 1990 to 2019. DESIGN: We evaluated the female infertility global burden between 1990 and 2019 in this systematic study. MATERIALS…

OBJECTIVES: Endometriosis (EM) is a chronic disease severely impacting reproductive health, with its exact cause still unclear. In-depth understanding of the etiology and pathogenesis of EM from the perspective of genetics and exploring ind…

OBJECTIVE: The objective of this study was to investigate the impact of localization of diffuse adenomyosis on reproductive outcomes after frozen embryo transfer (FET). DESIGN: This prospective cohort study was conducted between January 20…

OBJECTIVES: A recent study has shown that myofibroblasts are primed for apoptosis when survival pathways are inhibited under fibrosis. This knowledge of apoptosis priming led to the development of methods to induce apoptosis specifically in…

OBJECTIVES: Endometriotic stromal cells (ESCs) are extensively found in endometriosis (EM). This study aims to investigate the effects and regulatory mechanisms of KLF10 on the proliferation of ESCs in EM. METHODS: Human ESCs from eutopic …

UNLABELLED: Introduction: Endometriosis is a chronic gynecological disorder characterized by the ectopic growth of endometrial-like tissue, with emerging evidence highlighting a significant genetic contribution to its etiology. While genome…

BACKGROUND: Endometriosis is a chronic gynecological condition that affects approximately 10% of women of reproductive age globally. It is associated with significant morbidity due to symptoms such as pelvic pain and infertility. Current kn…

BACKGROUND: Accessory and cavitated uterine masses (ACUM) are rare Mullerian anomalies, defined as an isolated accessory cavitated mass lined with endometrial epithelium. OBJECTIVES: This article explores ACUM lesions from two aspects and …

BACKGROUND: There is a paucity of studies on the association between polycystic ovary syndrome (PCOS) and endometriosis and the occurrence of venous thromboembolism (VTE). OBJECTIVE: Our study aimed to evaluate the association between PCOS…

OBJECTIVES: This study aimed to explore potential differences in efficacy between vaginal progesterone (VPG) and VPG + oral progesterone (OPG) for luteal-phase support in hormone replacement therapy-frozen embryo transfer (HRT-FET) cycles. …

BACKGROUND: Endometriosis-related infertility and its treatment with assisted reproductive technologies (ART) have been broadly researched. Yet, underlying mechanisms of infertility, particularly in the absence of tubal dysfunction, remain …

OBJECTIVE: Endometriosis is a chronic gynecological disorder that can cause infertility in women of reproductive age, and its clinical treatment still faces significant challenges. However, the pathogenesis of endometriosis remains unclear.…

INTRODUCTION: Endometriosis is a condition that leads to a chronic inflammatory state, which has been associated with pelvic pain and infertility. Ovarian endometriomas are commonly treated via laparoscopic cystectomy; however, there is som…

BACKGROUND: Embryo implantation and early survival in a synchronized, receptive endometrium are critical for establishing a successful pregnancy, but uterine pathologies can present challenges to reproductive success by significantly impact…

BACKGROUND: The nature and functions of the innermost layer of the myometrium, which is located immediately below the endometrium, coined the "junctional zone" (JZ), continue to be the subject of debate. The role and significance of the JZ …

BACKGROUND: Bowel endometriosis is one of the more severe manifestations of deep endometriosis; it may cause pain and intestinal symptoms. The noninvasive diagnosis of bowel endometriosis is of crucial importance in planning the management …

BACKGROUND: Over the past decade, transvaginal ultrasound (TVUS) has revolutionized the diagnosis of deep endometriosis. We can now accurately describe and evaluate lesions in multiple compartments of the pelvis, increasing diagnostic capac…

BACKGROUND: No conceptually new drugs for the safe and successful cure of endometriosis are likely to become available soon. Hormonal modulation of ovarian function and suppression of menstruation remain the pillars of disease control. Howe…

OBJECTIVES: The aim of the study was to evaluate current practices among gynecologists in managing large endometriomas before in vitro fertilization (IVF). DESIGN: A cross-sectional online survey was conducted. Participants/Materials: The …

OBJECTIVES: The objective of this multicenter retrospective study aimed to evaluate the association of clinical variables and the incidence of ovarian cancer in patients with BRCA 1-2 mutation carriers who underwent risk-reducing salpingo-o…

OBJECTIVE: Abnormal expression of circular RNA (circRNA) leads to the occurrence and development of endometriosis (EM), but its underlying mechanisms are largely unknown. METHODS: Abnormally expressed circRNAs were screened in EM and norma…

INTRODUCTION: Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder in women. At present, the pathogenesis has not been clarified, and the clinical application of drugs and lifestyle intervention may not prevent dise…

OBJECTIVES: The objective of the study was to evaluate the prevalence and impact of impaired thyroid-stimulating hormone (TSH) levels on the reproductive outcomes of in vitro fertilization patients diagnosed with endometriosis and compared …

BACKGROUND: Pelvic congestion syndrome (PCS) is a poorly understood condition that can be associated with chronic pelvic pain and could impact quality of life. The diagnosis is often made by exclusion of other causes of pelvic pain. OBJECT…

OBJECTIVES: Luteinizing hormone (LH) plays a key role in normal follicular development and oocyte maturation in controlled ovarian stimulation. LH stimulates the proliferation and differentiation of theca cells for the secretion of androgen…
