Cigarettes affect erection

And not just regular cigarettes, but electronic cigarettes as well.

A study by Omar El-Shahawy et al. (2022) published in the American Journal of Preventive Medicine showed that e-cigarettes significantly increased the risk of erectile dysfunction in 13 711 men they studied, especially among those who smoked every day.

Scientists explain that nicotine prevents blood vessels from dilating and disturbs the normal flow of blood.

Smokers also show slower production of testosterone, which also seems to have a negative impact on erection. So it turns out e- cigarettes aren't that harmless.
