There are countless reasons to keep a healthy weight and erectile functioning is among them. "Losing weight or maintaining a healthy body weight is extremely important for overall cardiovascular fitness and for erectile health," says Breyer.

Diabetes, which is closely associated with being overweight or obese, can also lead to nerve damage in the penis.
