Adnexal cystic torsion is a gynecological emergency that requires prompt and accurate diagnosis followed by immediate surgical intervention to preserve ovarian function. Although ultrasound or computed tomography (CT) are commonly employed,…

Age-related decline in oocyte quality is closely associated with mitochondrial dysfunction and oxidative imbalance, which disrupt redox-sensitive meiotic signaling and compromise embryo developmental competence. Rescue in vitro maturation (…

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…

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/Objectives: Our study evaluates the performance of the CDO1 and CELF4 methylation assay of cervical scrapings in diagnosing endometrial cancer. Methods: Patients referred for abnormal uterine bleeding, suspected endometrial patho…

This study examined the impact of hormone replacement therapy (HRT) on the occurrence of various cancers in postmenopausal women with de novo or a history of endometriosis. In the datasets for ten cancers (cervical, uterine, ovarian, breast…

The effect of hormone replacement therapy (HRT) on the malignant transformation of postmenopausal endometriosis remains unclear. This study aimed to investigate the impact of HRT on ovarian cancer occurrence in postmenopausal women with de …

Cadmium (Cd), a harmful heavy metal, can lead to various pulmonary diseases, including chronic obstructive pulmonary disease (COPD), by inducing cytotoxicity and disturbing redox homeostasis. The aim of the present study was to investigate …

Spinal extradural arachnoid cyst (SEAC) is a rare disease and has surgical challenges because of the critical surrounding anatomy. We describe the rare case of a 58-year-old woman who underwent extradural cyst total excision with dural repa…

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 …

BACKGRUOUND: Texture analysis has been used as a method for quantifying image properties based on textural features. The aim of the present study was to evaluate the usefulness of magnetic resonance imaging (MRI) texture analysis for the ev…

Alteration in expression of miRNAs can cause various malignant changes and the metastatic process. Our aim was to identify the miRNAs involved in cervical squamous cell carcinoma (SqCC) and metastasis, and to test their utility as indicator…

BackgroundArthroscopic capsular release is an effective treatment for refractory shoulder stiffness, yet there are no basic studies that can explain the extent of the release.PurposeThis study aimed to compare the genetic expression of infl…

OBJECTIVE: The objective of this study is to evaluate the preoperative hematological parameters to predict ovarian torsion in patients with ovarian mature cystic teratoma. We also analyzed the diagnostic value of these makers to predict ova…

Thymic stromal lymphopoietin (TSLP) is an epithelial cell derived cytokine belonging to the IL-7 family and a key initiator of allergic inflammation. Two main isoforms of TSLP, classified as long- (lfTSLP) and short-form (sfTSLP), have been…

PURPOSE: The purpose of this study was to evaluate clinical characteristics and treatment pattern of ovarian clear cell carcinoma (OCCC) in Korea and the role of adjuvant chemotherapy in early stage. MATERIALS AND METHODS: Medical records …

OBJECTIVE: Serum antimüllerian hormone (sAMH) is regarded as a useful marker in predicting for ovarian functional reserve. To evaluate whether postoperative change in ovarian reserve differs between robotic-assisted and laparoscopic single-…

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…

Introduction: A Tarlov cyst (TC) is a perineural cyst filled with cerebrospinal fluid that originates from the dorsal ganglion or the spinal posterior nerve root. TCs are usually asymptomatic and incidentally found in the sacral region. End…

To compare the genetic distributions of 14G protein-coupled receptor 30 (GPR30) single-nucleotide polymorphisms (SNPs) between women with and without uterine adenomyosis. The study population comprised 69 Korean women. Uterine tissues from …

BACKGROUND: To minimize damage to the ovarian reserve, it is necessary to evaluate the follicular density in the ovarian tissue surrounding endometrioma on preoperative imaging. The purpose of the present study was to evaluate the usefulnes…
