Background: Endometriosis affects approximately 6-10% of women of reproductive age-an estimate that varies substantially with the diagnostic standard applied-and is increasingly recognized as a systemic inflammatory disease. Growing evidenc…

Endometriosis, a prevalent but debilitating condition affecting women, poses significant challenges in diagnosis and management. The current 2024 guideline, developed by the Korean Society of Endometriosis (KSE), builds upon the 2018 KSE gu…

PURPOSE: Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with adverse reproductive and obstetric outcomes, particularly in pregnancies achieved through assisted reproductive technologies. This study aimed to compa…

Background: This study aimed to evaluate ovarian reserve in patients with unilateral endometrioma by exploring correlations between serum anti-Müllerian hormone (AMH) levels and imaging markers derived from ultrasonography and magnetic reso…

Chronological age is an imprecise proxy for reproductive capacity, necessitating biomarkers that reflect the underlying pathophysiology of the ovary. Fibrotic remodeling of the ovarian stroma is a key hallmark of biological ovarian aging, y…

OBJECTIVE: To compare obstetric and perinatal outcomes between assisted reproductive technology (ART)-conceived and spontaneously conceived twin pregnancies using a nationwide Korean cohort. METHODS: This retrospective cohort study used Ko…

BACKGROUND: Endometriosis is a common cause of infertility in women of reproductive age, and many affected women require assisted reproductive technology (ART) to conceive. It is also associated with increased risks of adverse obstetric com…

BACKGROUND: The aim of this study was to examine various patient factors affecting first programmed embryo transfer (ET) outcomes under the freeze-all policy at a single tertiary university infertility center. METHODS: This retrospective o…

Background: The aim of this study was to evaluate the efficacy of ultrasonography-guided cyst aspiration followed by dienogest medication in the management of endometriomas in selected patients.Methods: This study included 38 female patient…

BACKGROUND: This study aimed to investigate the obstetric and perinatal outcomes of singleton deliveries following frozen embryo transfer (FET) cycles using different endometrial preparation methods. METHODS: We analyzed data on 44,118 sin…

Endometriosis is a gynecological disease prevalent in women of reproductive age, and it is characterized by the ectopic presence and growth of the eutopic endometrium. The pathophysiology and diagnostic biomarkers of endometriosis have not …

Objectives To evaluate the side effects and causes of discontinuation of either combined oral contraceptives or dienogest (DNG) used to prevent recurrence in patients with surgically confirmed endometriosis. Methods We retrospectively analy…

OBJECTIVE: The aim of this study was to investigate and compare the dietary patterns of Korean women diagnosed with endometrioma or other benign ovarian cysts. METHODS: A total of 66 patients, comprising 39 patients who were surgically dia…

OBJECTIVES: The purpose of this study was to identify clinical risk factors for the recurrence of ovarian endometrioma after ovarian cystectomy in Korean women with long-term postoperative medical therapy. MATERIAL AND METHODS: A total of …

BACKGROUND AND OBJECTIVE: The aim of this study was to characterize primary cells from extrauterine carcinosarcoma (CS) and to establish a primary CS xenograft mouse model. METHODS: Primary cells were isolated from a patient with CS and cu…
