I recently came across another older, interesting article that links obesity and erectile dysfunction.  Certainly no shortage of research in this area.

There are some scary statistics that could serve as great motivation to focus not only on sexual health, but overall bodily health.

Wish everyone well.

Obesity disturbs the functioning of the male reproductive system by reducing the blood supply to the penis. This happens as the fats get deposited around the arteries and put the pressure on the arterial walls disturbing the blood supply. Thus, erectile dysfunction is noted in the men.
