Identification of Single Nucleotide Polymorphisms as Biomarkers for Recurrent Pregnancy Loss in Korean Women.

Background: Single nucleotide polymorphisms (SNPs) are reportedly associated with repeated abortion. Thus, genetic analysis based on race is the key to developing accurate diagnostic tests. This study analyzed the genetic polymorphisms of recurrent pregnancy loss (RPL) patients among Korean women compared to the controls.

Fertility of patients with polycystic ovary syndrome undergoing in vitro fertilization by age.

Objective: To evaluate outcomes of in vitro fertilization (IVF) among patients with polycystic ovary syndrome (PCOS) by age.

Methods: In a retrospective study, data were retrieved for patients with PCOS (Rotterdam 2003 criteria) and individuals with tubal factor infertility who underwent IVF at a center in Seoul, South Korea, between January 2003 and August 2012. IVF outcomes were compared by age group (A: 30-32 years; B: 33-35 years; C: 36-38 years; D: 39-41 years).

The Risk Factors and Pregnancy Outcomes of 48 Cases of Heterotopic Pregnancy from a Single Center.

The purpose of this study was to investigate risk factors that are associated with heterotopic pregnancy (HP) following in vitro fertilization (IVF)-embryo transfer (ET) and to demonstrate the outcomes of HP after the surgical treatment of ectopic pregnancies. Forty-eight patients from a single center, who were diagnosed with HP between 1998 and 2012 were included. All of the patients had received infertility treatments, such as Clomid with timed coitus (n = 1, 2.

Early gonadotropin-releasing hormone antagonist start improves follicular synchronization and pregnancy outcome as compared to the conventional antagonist protocol.

Objective: To assess whether an early GnRH antagonist start leads to better follicular synchronization and an improved clinical pregnancy rate (CPR).

Methods: A retrospective cohort study. A total of 218 infertile women who underwent IVF between January 2011 and February 2013.

Can high serum anti-Müllerian hormone levels predict the phenotypes of polycystic ovary syndrome (PCOS) and metabolic disturbances in PCOS patients?

Objective: To evaluate correlations between serum anti-Müllerian hormone (AMH) levels, phenotypes of polycystic ovary syndrome (PCOS), obesity, and metabolic parameters in patients with PCOS.

Methods: A total of 175 patients with PCOS were diagnosed according to the Rotterdam Consensus were included. Exclusion criteria were age over 40, FSH>25 mIU/mL, and 17a-OHP>1.

The feasibility of scarless single-port transumbilical total laparoscopic hysterectomy: initial clinical experience.

Objective: The purpose of the present study is to demonstrate the feasibility of single-port transumbilical laparoscopic surgery (SPLS) for hysterectomy and elaborate on our experience in order to introduce the single-port approach for gynecologic surgery.

Methods: Between August 2008 and February 2009, 30 patients who initially planned to undergo single-port laparoscopic surgery at Yonsei University Health System in Seoul, Korea were enrolled in this study. The authors used a single-port three-channel system with a wound retractor, surgical gloves, and one 10/11-mm and two 5-mm trocars.
