Objective: To identify whether variants found in a large Han Chinese cohort - 8q22.3 SNPs rs3847153 and rs3108910; and one SNP each in HK3 (rs2278493), ESR1 (rs2234693) and BRSK1 (rs12611091) - are associated with premature ovarian failure (POF) in a different ethnic group (Serbian).
Design: Case-control genetic association study in 197 Serbian POF cases and 552 matched controls.
Results: None of the SNPs found associated with POF in Chinese cohort were found to be associated in the Serbian sample.
Conclusions: In contrast to Han Chinese, no association was found between POF in Serbian women and any of the four tested loci: 8q22.3, HK3, ESR1 and BRSK1. This indicates that ethnically distinct populations may show differences in gene-regulating pathways and genes causing POF.

Aim: This study aims to assess the impacts of various trigger day progesterone (P) and luteinizing hormone (LH) levels on live birth rates (LBRs) in fresh in vitro fertilization (IVF) cycles, considering their elevation from stimulation and premature luteinization.
Methods: This retrospective cohort study included the first ovarian stimulation cycles with GnRH antagonist protocol of 1253 patients who underwent intracytoplasmic sperm injection and fresh embryo transfer at a tertiary clinic's IVF center between 2010 and 2016. Participants were divided into four groups based on trigger day serum P and LH levels, using the 90th percentile thresholds for P (1.

Study Question: Is elevated plasma molybdenum level associated with increased risk for idiopathic premature ovarian insufficiency (POI)?
Summary Answer: Elevated plasma molybdenum level is associated with an increased risk of idiopathic POI through vascular endothelial injury and inhibition of granulosa cell proliferation.
What Is Known Already: Excessive molybdenum exposure has been associated with ovarian oxidative stress in animals but its role in the development of POI remains unknown.
Study Design, Size, Duration: Case-control study of 30 women with idiopathic POI and 31 controls enrolled from August 2018 to May 2019.

Background: Premature Ovarian Failure (POI), a prevalent gynecological, endocrine disease, significantly impairs the reproductive health of women of childbearing age and presents a formidable challenge to clinicians. Until now, there has been a lack of effective treatments to fundamentally improve ovarian function in patients with POI. Stem cell therapy has emerged as a promising treatment in the field of POI, with notable research progress achieved to date.

The objective of this study was to examine the efficacy of the concurrent utilization of estradiol valerate and kuntai capsule (a Chinese herbal preparation) in addressing premature ovarian failure (POF) and its ramifications for ovarian hemodynamics and sex hormone levels. A retrospective study of 104 patients with POF was conducted, dividing them into control (n=50) and observation groups (n=54). The control group received estradiol valerate, while the observation group received estradiol valerate and KunTai capsules over 12 weeks.
