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…

OBJECTIVE: Laser-assisted hatching (LAH) employs two distinct techniques: thinning and breaching. This study aimed to compare the clinical efficacy of combined thinning and breaching versus breaching alone in vitrified-warmed embryo or blas…

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…

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

OBJECTIVE: This study investigated the clinical and laboratory factors associated with the presence of dysmorphic oocytes in intracytoplasmic sperm injection (ICSI) cycles. METHODS: The study involved 200 ICSI cycles, performed from 2020 t…

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…

OBJECTIVE: The aim of this study was to assess the correlation of oocyte number with serum anti-Müllerian hormone (AMH) levels measured by two automated methods (Access or Elecsys) in fresh stimulated in vitro fertilization (IVF) cycles. M…

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…

PURPOSE: The present study aimed to identify microorganisms in follicular fluids and to investigate their association with in vitro fertilization (IVF) outcomes. MATERIALS AND METHODS: This study was conducted as a prospective study of 49 …

OBJECTIVE: This study aimed to investigate sperm motility and its changes after preparation as predictors of pregnancy in intrauterine insemination (IUI) cycles. METHODS: In total, 297 IUI cycles from January 2012 to December 2017 at a sin…

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…

OBJECTIVE: We attempted to identify the optimal cutoff numbers of mature oocytes that would produce at least one or multiple top-quality (grade A) day-3 embryos in normal responders undergoing stimulated in vitro fertilization (IVF) cycles.…

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 …

PURPOSE: To 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 METHODS: Fifty-three co…

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…

OBJECTIVE: The purpose of this retrospective study was to evaluate the appropriateness of various follicle-stimulating hormone (FSH) starting doses in expected normal responders based on the nomogram developed by La Marca et al. METHODS: A…

OBJECTIVE: To 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 em…

OBJECTIVE: To 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. METHOD: Two …

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 s…

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…
