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…

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…

Endometriosis is a chronic gynecological disorder characterized by the presence of endometrial-like tissue outside the uterus, leading to inflammation, pain, and infertility. Emerging evidence indicates that endometriotic lesions exhibit ca…

Bowel perforation secondary to a levonorgestrel-releasing intrauterine device is exceptionally rare. We present the case of a woman who exhibited abnormal findings during a colonoscopy examination. Despite undergoing an intrauterine device …

This study investigated the impact of menopause on the progression and management of common benign gynecological conditions such as polycystic ovary syndrome, endometriosis, uterine fibroids, and adenomyosis. These conditions often present …

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…

BACKGROUND: Frankincense, a resin derived from trees of the Boswellia genus, has been used as an incense and a type of herbal medicine for treating inflammatory diseases such arthritis, chronic bowel illness, and asthma. While endometriosis…

Endometriosis is a prevalent benign illness defined by the presence of endometrial glands and stroma outside of the uterine cavity, primarily on the ovary, pelvic peritoneum, and rectovaginal septum, resulting in a variety of symptoms, incl…

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 …

Endometriosis is a common gynecological disease defined as the growth of endometrial tissues outside the uterus. Although the mechanism underlying the progression of endometriosis has not been fully elucidated, cancer-like aerobic glycolysi…

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…

PURPOSE: To investigate the efficacy and safety of a newly developed thermo-responsive sol-gel, ABT13107, for reducing the formation of intrauterine adhesions (IUAs) after hysteroscopic surgery. MATERIALS AND METHODS: In this multicenter, …

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…

Purpose: The aim of this study is to evaluate the association between body mass index (BMI) and endometriosis in Korean women. Materials and Methods: In a hospital-based case-control study, 134 endometriosis cases and 282 ovarian teratoma c…

OBJECTIVES: The aim of this study is to evaluate the impact of ovarian endometrioma according to its size on the serum anti-Mullerian hormone (AMH) levels compared to that of other benign ovarian cysts. MATERIAL AND METHODS: The current st…

BACKGROUND: Tumor markers are useful for detection and preoperative evaluation of ovarian tumors. We evaluated the clinical usefulness of cancer antigen (CA) 125, human epididymis 4 (HE4), and CA72-4 levels and Risk of Ovarian Malignancy Al…

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 …
