PURPOSE: This study aims to analyze the clinical factors affecting embryo quality and quantity in endometriosis patients undergoing in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET), thereby providing…

AIM: This exploratory pilot study aimed to assess the preliminary clinical effects of leuprorelin acetate microspheres for injection [gonadotropin-releasing hormone agonist (GnRH-a)] combined with levonorgestrel-releasing intrauterine syste…

This FIGO committee opinion paper addresses the growing body of evidence linking environmental exposures to common gynecologic and reproductive conditions across the life course. From adolescence through menopause, women are exposed to a wi…

BACKGROUND: Endometriosis is a common gynecological disorder among women of reproductive age worldwide. This study aims to examine global patterns of endometriosis disease burden among reproductive-aged women and to evaluate its correlation…

Adenomyosis is a common gynecological condition affecting women of reproductive age, posing significant diagnostic challenges due to its diverse clinical presentations. This extended opinion study critically reviews the diagnostic methods f…

BACKGROUND: Some infertile women can undergo spontaneous conception after 4-dimensional hysterosalpingo-contrast sonography (4D-HyCoSy). However, advised period of expectant management after HyCoSy for different tubal patency was rarely rec…

INTRODUCTION: Endometriosis is delineated as a benign yet steroid-dependent disorder characterized by the ectopic presence of endometrial glandular and stromal cells outside the uterine cavity, affecting estimated 10%-15% of women of reprod…

Non-persistent endocrine-disrupting chemicals (EDCs) are of significant concern due to their reproductive toxicity. Previous research reported a relationship between a single type of EDCs and endometriosis. Yet, evidence regarding mixed exp…

This was a retrospective study that evaluated a total of 280 patients who underwent surgery for complete removal of endometriosis to develop and validate the predictive model for stage IV endometriosis. The differences between stage I-III a…

This study was carried out to elucidate the biological function of HOTAIR in granulosa cells of endometriosis and the underlying mechanism. Granulosa cells were extracted from endometriosis patients and subjects with fallopian tube factor a…

Endometriosis is a gynecological disease that endometrial cells develop outside the uterus. This event happens when the endometrial glands grow outside the endometrium and uterine muscles, especially in the pelvis. Although endometriosis is…

ABSTRACT: Triptorelin has been used after surgery in deep infiltrating endometriosis. This post-hoc analysis aimed to evaluate symptom control between patients receiving 1-3 triptorelin injections and those receiving 4-6 injections within 2…

BACKGROUND: Women with endometriosis and previous cystectomy may respond less well to gonadotropin stimulation, which results in fewer oocytes retrieved and poor pregnancy outcomes. Choosing an appropriate protocol for such populations is e…

Ovarian follicular development is a complex process that requires codevelopment of the perifollicular vascular network, which is closely regulated by angiogenic factors, gonadotropins, sex steroids, and their metabolites. To detect the effe…

OBJECTIVE: To evaluate the clinical usefulness of the microbubble contrast agent SonoVue in enhancing high-intensity focused ultrasound (HIFU) for the treatment of adenomyosis. METHODS: A total of 102 patients with adenomyosis, assessed fro…

STUDY QUESTION: Is there a specific mechanism underlying the association between lung adenocarcinoma transcript 1 (MALAT1) and endometriosis-related infertility? SUMMARY ANSWER: The down-regulation of MALAT1 in endometriosis granulosa cells…

OBJECTIVES: The aim of this study was to investigate the relationship between 25-hydroxyvitamin-D [25(OH)D] and female infertility and to further explore the role of inflammatory cytokines. METHOD: We recruited 356 infertile women diagnose…

Endometriosis, which affects up to 10% of women of reproductive age, is defined as endometrial-like gland and stroma tissue growths outside the uterine cavity. Despite increasing research efforts, there are no current effective treatment me…

OBJECTIVE: To study the effectiveness and safety of combined laparoscopy and gonadotropin-releasing hormone agonist (GnRH-a) in the treatment of endometriosis (EM). METHODS: From January to December 2010, 198 patients with EM undergoing tre…

OBJECTIVE: To investigate the influence on ovarian reserve function in treatment of ovarian endometriotic cyst by laparoscopic cystectomy with various hemostasis management. METHODS: From September 2007 to August 2008, 61 patients with bila…

Objective:To study the influence on ovarian function after operation with electric coagulation in stripping endometriotic cyst under laparoscopy.Methods:39 patients with endometriotic cyst were chosen and performed with the hemostatic metho…
