This review focuses on the role of the ovaries in the pathogenesis of the polycystic ovarian syndrome. In particular, the failure of follicular development, hypothalamo-pituitary dysregulation, alterations in adrenal steroid output and derangement of intermediary metabolism are discussed in the context of the ovaries. It is concluded that the central and adrenal alterations associated with PCOS are unlikely to be primary but rather are secondary to the events within the ovary.

Purpose: To investigate BMAL1 and BMP6 expressive differences in ovarian granulosa cells (OGCs) of patients with polycystic ovary syndrome (PCOS), explore regulatory relationship, assess their impacts on OGC proliferation and apoptosis, and analyze their correlations with ART outcomes of patients.
Methods: A clinical study selected 40 PCOS patients who underwent IVF/ICSI in our hospital from January to October 2022 and 39 controls with male or tubal factor infertility. RT-qPCR and Western blot assessed BMAL1 and BMP6 mRNA/protein levels.

Objectives: Polycystic ovary syndrome (PCOS) represents a significant and persistent metabolic disorder, emerging as a leading factor contributing to infertility. Despite its profound impact, there remains an inadequate understanding of the global burden of PCOS-related infertility across diverse regions and countries. The aim of this study was to evaluate the global, regional, and national burden of PCOS-related infertility from 1990 to 2019.

This study aimed to evaluate the comparative efficacy of Myo-inositol (MI) and D-chiro-inositol (DCI) with metformin in enhancing ovarian function, promoting ovulation, and reducing perceived stress in patients with polycystic ovary syndrome (PCOS). Women with PCOS were identified using the Androgen Excess Society's criteria, and 60 participants were enrolled and divided equally into two groups. One group received a 40:1 ratio of MI plus DCI, while the other received metformin for a 12-week period.

Background: Polycystic Ovarian Syndrome (PCOS) is an endocrine disorder associated with increased risk of kidney and liver damage. Current treatments have shown contradictory outcomes, and their long-term use causes unwanted side effects. could serve as a complementary medicine to current PCOS treatments.

Androgen excess and metabolic abnormality largely contribute to the pathogenesis of polycystic ovarian syndrome (PCOS), which primarily precipitates ovarian dysfunction and infertility in reproductive-age women. Impaired mitochondrial function and epigenetic alteration have been linked to the development of PCOS. However, it is unknown whether acetate would exert a therapeutic effect on ovarian mitochondrial dysfunction in PCOS.
