It can be due to excessive sun exposure, hormonal changes and post-inflammatory hyperpigmentation (i.e after Acne)

Oncogenic functions of the transcription factor Nrf2

A small clinical trial of 45 subfertile men found that zinc sulfate supplementation was associated with an increase in sperm concentration of approximately 18.5 million/mL from baseline, though the small sample size (n=11 per group) means this finding requires confirmation in larger trials

Moreover, this modification has a regulatory roles in the function of proteins, as in the case of Heat Shock Protein 70 (HSP70), where the S-glutathionylated form mimics a substrate-binding condition [67], or in glyceraldeyde-3 phosphate dehydrogenase (GAPDH) where the GSH-mixed enzyme is enzymatically inactive [68]
