Background/Objectives: Oxidative stress is a critical factor in the development and progression of endometriosis. Granulosa cells, which reside near oocytes in follicles, exhibit steroidogenic activity, and, consequently, influence oocyte q…

Women with endometriosis often experience diminished ovarian reserve and a decreased number of oocytes retrieved. This reduction is exacerbated after surgery. Nevertheless, oocyte quality does not seem to be compromised in these patients. W…

We evaluated the clinical outcomes of using type 1 collagen gel after therapeutic resectoscopy; overall, 150 women aged > 20 who planned to undergo therapeutic resectoscopy were enrolled. The patients were randomly assigned to either of the…

Histone deacetylase inhibitors (HDACi) induce apoptosis preferentially in cancer cells by caspase pathway activation and reactive oxygen species (ROS) accumulation. Suberoylanilide hydroxamic acid (SAHA), a HDACi, increases apoptosis via al…

OBJECTIVE: To investigate whether high-mobility group box-1 induces cell proliferation, invasion and mediates inflammation in ectopic human endometrial stromal cells through Toll-like receptor 4. METHODS: Ectopic endometrial specimens were…

Decidualization is characterized by the differentiation of endometrial stromal cells (eSCs), which is critical for embryo implantation and maintenance of pregnancy. In the present study, we investigated the possible effect of simulated micr…

ObjectiveThe aim of this study was to evaluate the effectiveness of postoperative levonorgestrel-releasing intrauterine system (LNG-IUS) insertion after gonadotropin-releasing hormone agonist (GnRH-a) treatment for preventing endometriotic …

To investigate the effects of trichostatin A (TSA) on nonsteroidal anti-inflammatory drug-activated gene 1 (NAG-1) expression and apoptosis in human endometriotic stromal cells (HESCs), ectopic endometrial tissues were obtained from 15 pati…

Oxidative stress has been proposed as a potential factor associated with the establishment and progression of endometriosis. Although a few studies have shown possible mechanisms which may play roles in development, progression of endometri…

OBJECTIVE: Endometriosis is a common gynecological disorder caused by ectopic implantation of endometrial glandular and stromal cells outside the uterine cavity. Among several types of endometriosis, endometrioma is the only subtype that co…

OBJECTIVES: Lymphangiogenesis may be involved in the pathogenesis of adenomyosis. We investigated the lymphatic vessels of patients with adenomyosis, including those treated with levonorgestrel-releasing intrauterine system (LNG-IUS). METHO…

PURPOSE: This study aimed to evaluate the prognostic value of each component of the revised American Fertility Society (rAFS) classification system for the first recurrence of endometriosis after conservative laparoscopy. MATERIALS AND METH…

OBJECTIVE: The aim of this study is to validate and investigate the clinical value of urinary enolase I in patients with endometriosis. METHODS: Urine samples of 39 patients with histologically confirmed endometriosis and 20 patients withou…
