Moreover, the blockade of glutathione synthesis alone might not be sufficient to enhance oxidative stress and cell death, as the reduced glutathione pool might be partially regenerated from the oxidized glutathione pool (47)
It is important to note that the physico-chemical properties (e.g., complex formation, nucleophilic reactivity, redox properties) and biological functions of glutathione could be significantly different at different protonation states (i.e., in solutions with different pH values) [90,91,92,93] and its redox behavior [94,95]
The updated 2018 diagnostic criteria for PCOS require the presence of at least two of the following three features: (1) oligo/anovulation, (2) clinical and/or biochemical hyperandrogenism, and (3) PCO identified by the presence of 20 antral follicles per ovary on transvaginal ultrasound, with or without increased ovarian volume
