studies show that it lowers testosterone up to 50%, causes lots of oxidative stress to testicles, reduces sperm count and fertility labels.
Exposure to e-liquid, with or without nicotine, resulted in a marked decrease in circulating testosterone levels (by 50% and 30%, respectively) because of a decrease in the messenger RNA (mRNA) expression of two key steroidogenesis enzymes, cytochrome P450scc and 17β-Hydroxysteroid dehydrogenases (17β-HSD).
