Associations of Essential and Non-Essential Trace Elements' Levels in the Blood, Serum, and Urine in Women with Premature Ovarian Insufficiency.

Premature ovarian insufficiency (POI) is poorly understood, with causes identified in only 25% of cases. Emerging evidence suggests links between trace elements (TEs) and POI. This study is the first to compare concentrations of manganese (Mn), copper (Cu), zinc (Zn), selenium (Se), molybdenum (Mo), arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) across urine, serum, and whole blood in women with POI compared to healthy controls (HC), aiming to explore their distribution and potential associations with POI.

Negative effects of endocrine disruptor bisphenol A on ovarian granulosa cells and the protective role of folic acid.

In Brief: Bisphenol A (BPA) is a widely produced chemical, mostly used in the production of polycarbonate plastics, and can act as an endocrine disruptor. This paper focuses on the different effects of BPA on ovarian granulosa cells.

Abstract: Bisphenol A (BPA) is an endocrine disruptor (ED), widely used as a comonomer or an additive in the plastics industry.
