OBJECTIVE: This study investigated whether the average oocyte quality index (AOQI), used as a dysmorphic oocyte scoring system, is higher in women with ovarian endometrioma than in those with unexplained infertility or diminished ovarian re…

AIM: The purpose of the study was to compare the ovarian reserve after cystectomy of ovarian endometrioma by bipolar coagulation, suture method, or hemostatic sealants (HSs). METHODS: We performed a meta-analysis of studies in which post-c…

This study aimed to compare the impact of ablation and cystectomy for ovarian endometrioma on ovarian reserve, recurrence rates, and pregnancy rates. Databases were searched for studies reporting ovarian reserve (measurement of anti-mülleri…

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…

BackgroundFemale infertility is a crucial problem with significant implications for individuals and society. In this study, we explore risk factors for infertility in Korean women.MethodsA total of 986 female patients who visited six major …

OBJECTIVE: This study aimed to retrospectively analyze the cumulative pregnancy rate (PR) via multiple fresh or frozen embryo transfers (ET) in women with current, resected, or recurred endometrioma. MATERIALS AND METHODS: The IVF data inc…

Ovarian cystectomy is the preferred technique for the surgical management of ovarian endometrioma. However, other techniques such as ablation or sclerotherapy are also commonly used. The aim of this review is to summarize information regard…

PurposeThe present study aimed to identify microorganisms in follicular fluids and to investigate their association with in vitro fertilization (IVF) outcomes.Materials and methodsThis study was conducted as a prospective study of 49 infert…

This corrects the article "Management of endometriosis-related infertility: Considerations and treatment options" in Volume 47 on page 1.

Endometriosis is a common inflammatory disease in women of reproductive age and is one of the major causes of infertility. Endometriosis causes a sustained reduction of ovarian reserve through both physical mechanisms and inflammatory react…

This study aimed to analyze the effects of a new protocol with letrozole on the outcomes of in vitro fertilization (IVF) cycles in women with endometriosis. This retrospective cohort study was conducted for women diagnosed with endometriosi…

AIM: To evaluate various adverse symptoms during short-term use of ulipristal acetate in women with uterine myomas (n = 90), adenomyosis (n = 3) or both (n = 7). METHODS: One hundred premenopausal women who received ulipristal acetate for 4…

PurposeTo investigate the associations between sperm DNA fragmentation (SDF) and embryo formation rate in normal responder women to in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI).Materials and methodsFifty-three consecut…

Posterior reversible encephalopathy syndrome (PRES) is a newly described adverse effect possibly associated with gonadotropin-releasing hormone (GnRH) agonist therapy. We report a case of PRES after 2 doses of depot GnRH agonists in a 44-ye…

ObjectiveTo compare the clinical pregnancy rate (CPR) and ongoing pregnancy rate (OPR) in frozen embryo transfers (FETs) following either freeze-all policy to prevent ovarian hyperstimulation syndrome (OHSS; freeze-all group) or excess embr…

ObjectiveTo investigate prevalence of antiphospholipid antibody (APA) in Korean infertile women undergoing the first in vitro fertilization (IVF) treatment and to evaluate the influence of APA on the subsequent IVF outcomes.MethodTwo hundre…

OBJECTIVE: This study aimed to determine whether the menstrual characteristics are different in Korean women with or without ovarian endometrioma. METHODS: We selected 95 premenopausal women aged below 39 years who underwent laparoscopic su…

The purpose was to evaluate the effects of dienogest on Korean women with endometriosis. A cross-sectional questionnaire-based survey was conducted for 100 premenopausal women. They had taken or were taking 2 mg of dienogest daily. We asses…

OBJECTIVE: fertilization (IVF) outcomes between women with diminished ovarian reserve (DOR) after endometrioma operation and women with DOR without ovarian surgery. METHODS: This retrospective case-control study included 124 women aged unde…

OBJECTIVE: To estimate the incidence of falsely elevated risk of ovarian malignancy algorithm (ROMA) in a group of women with pathologically confirmed endometrioma and to investigate the associated factors. METHODS: One hundred premenopaus…

This study aimed to investigate the potential detrimental effect of human endometriotic fluids (EFs) on in vitro growth of mouse preantral follicles. Preantral follicles (isolated from ovaries of 7- to 8-week-old mice) were cultured in grow…

This study assesses the fertilization and blastocyst-forming rate in mice cumulus-oocyte complexes (COCs) after the exposure of human ovarian endometriotic fluid. Endometriotic fluid was obtained from a single patient by aspiration at the t…

OBJECTIVE: Elevated serum progesterone (P) levels on triggering day have been known to affect the pregnancy rate of in vitro fertilization (IVF). This study aimed to identify the possible factors influencing serum P levels on triggering day…

OBJECTIVE: To report the various anatomic locations of surgically and pathologically proven endometriosis. METHODS: Pathologic reports (n=1,376) of women who underwent surgeries at a single center between April 2005 and March 2013 were retr…
