TO INVESTIGATE: the prevalence of vitamin D deficiency in Korean women with polycystic ovary syndrome (PCOS), and relationship between status clinical or metabolic features this group.We recruited 38 PCOS using Rotterdam criteria. A total 109 premenopausal control were matched patients based on age body mass index. Serum 25-hydroxy concentrations less than 20 ng/mL classified as frank deficiency. Since may play a significant role disturbances PCOS, correlations parameters analyzed separately...

Objectives To determine the effect of acupuncture in treating hot flushes perimenopausal or postmenopausal women. Methods The study was a randomised single-blind sham-controlled clinical trial. Perimenopausal women with moderate severe were to receive real sham acupuncture. Both groups underwent 4-week run-in period before treatment. group received 11 treatments for 7 weeks, and control on non-acupuncture points during same period. followed 8 weeks after end treatment Changes from baseline...

Insulin resistance is a core feature of polycystic ovary syndrome (PCOS). Recently, genome-wide association studies have reported number single-nucleotide polymorphisms (SNPs) with reproducible associations and susceptibilities to type 2 diabetes. We examined the potential between diabetogenic genes uncovered in PCOS Korean women.Case-control study.Women or without PCOS.DNA samples from 377 patients 386 age-matched controls were genotyped.None 12 SNPs six (KCNJ11, TCF7L2, SLC30A8, HHEX, FTO...

Abstract STUDY QUESTION What is the impact of newly recommended antral follicle count (AFC) cutoff for polycystic ovary (PCO) on diagnostic status syndrome (PCOS)? SUMMARY ANSWER Among patients with phenotypes requiring presence PCO diagnosis, approximately half (48.2%) were excluded from having PCOS based new AFC cutoff, although these women had worse metabolic and hormonal profiles than controls indistinguishable remaining regard to major parameters.

The balance between coagulation and fibrinolysis is an essential part in early pregnancy. Mutations methylenetetrahydrofolate reductase (MTHFR) gene lead to decreased activity of the enzyme hyperhomocysteinemia, which then induces platelet aggregation by promoting endothelial oxidative damage, possibly resulting adverse effect on maintenance We investigated role MTHFR single nucleotide polymorphisms (SNPs), C677T A1298C, Korean patients with recurrent pregnancy loss (RPL). conducted a...

Serum anti-Müllerian hormone (AMH) levels are regarded as an age-specific marker for predicting the ovarian reserve in women of reproductive age. Some studies have shown that luteinizing (LH)/follicle stimulating (FSH) ratio can be used a predictor reserve. The purpose this study was to assess variation LH/FSH with aging and evaluate correlation between serum AMH normo-ovulatory women. We retrospectively analyzed day 3 1,251 patients (age range: 20-50 yr) January 2010 2011. divided into 6...

BACKGROUNDInsulin resistance is a core feature of polycystic ovary syndrome (PCOS). Phosphatidylinositol (PI) 3-kinase an important enzyme in the early insulin signaling cascade and plays key role insulin-mediated glucose transport. In its regulatory subunit, p85α, there common amino acid substitution (the Met326Ile polymorphism), this may be crucial for function p85α subunit PI3-kinase.
