Purpose: Anti-Müllerian hormone (AMH) inhibits FSH-stimulated follicle growth and aromatase activity. The three fold higher serum AMH in PCOS patients may account for the increased number of small follicles and androgen level. We attempted to determine whether polymorphisms in AMH gene were associated with PCOS in Chinese han population.
Methods: A case-control study involving 475 PCOS patients and 512 normoovulatory women was conducted. Rs10407022 and rs8112524 were two tagging SNPs selected according to the HapMap database. Taqman assay was used for rs8112524 genotyping, and PCR-RFLP method for rs10407022.
Results: No significant difference was found in genotypic or allelic distributions of both of the two SNPs, rs10407022 and rs8112524, between PCOS women and controls. LH level and progesterone level were significantly higher in rs8112524 AA genotype in PCOS group (P = 0.012, 0.014 respectively). TA haplotype might enhance susceptibility to PCOS (P = 0.013, OR = 4.996, 95 % CI = 2.001-5.251), and GA haplotype might be protective (P = 0.000, OR = 0.117, 95 % CI = 0.049-0.417).
Conclusions: Although individual TagSNPs in AMH gene do not affect susceptibility to PCOS, haplotypes of the two SNPs were associated with PCOS risk, as TA haplotype might enhance susceptibility to PCOS and GA inversely.

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder that affects women of reproductive age and is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology. PCOS is often associated with hormonal imbalances, metabolic dysfunction and comorbid psychiatric disorders, including eating disorders (EDs). The review identifies key hormonal factors-serotonin, leptin, insulin, ghrelin, kisspeptin and cortisol-and their roles in the pathophysiology of PCOS and associated psychiatric symptoms.

Background: A significant overlap in the pathophysiological features of polycystic ovary syndrome (PCOS) and type 2 diabetes mellitus (T2DM) has been reported; and insulin resistance is considered a central driver in both. The expression and hepatic clearance of insulin and subsequent glucose homeostasis are mediated by TCF7L2 via Wnt signaling. Studies have persistently associated TCF7L2 genetic variations with T2DM, however, its results on PCOS are sparse and inconsistent.

Research Question: Are the combined genotypes and haplotypes of vitamin D receptor (VDR) gene polymorphisms (FokI, ApaI and TaqI) associated with susceptibility to polycystic ovary syndrome (PCOS) and metabolic features of the disease?
Design: This case-control study included 46 women with PCOS and 48 controls. Genotypes of the VDR gene were determined using the polymerase chain reaction-restriction fragment length polymorphism method. Waist circumference, and parameters of lipid and glucose metabolism were evaluated in all women.

Background: Polycystic ovary syndrome (PCOS) is a complex endocrine disorder with various contributing factors. Understanding the molecular mechanisms underlying PCOS is essential for developing effective treatments. This study aimed to identify hub genes and investigate potential molecular mechanisms associated with PCOS through a combination of bioinformatics analysis and Mendelian randomization (MR).

Objectives: Polycystic ovary syndrome (PCOS) is a prevalent endocrine-metabolic disorder affecting reproductive-aged women. Genetic factors play a significant role in its development. This meta-analysis assesses the associations between specific gene polymorphisms (Vitamin D receptor [VDR] and adiponectin [ADIPOQ]) and PCOS susceptibility.
