How His Childhood Eating Habits Affect His Boner

As you're probably well aware, there are quite a few reasons why a guy might not be able to get hard. From his relationship with his mom to weird masturbation habits, you might think you've heard it all—but you would be wrong. His erection troubles might also be to blame on how much sugar he ate as a kid, according to a recent study published in The Journal of Sexual Medicine.

For the latest boner-killing study, researchers gave newborn male rats water spiked with different dosages of fructose (the type of sugar found in fruit). The control group drank regular water, a second group drank water with five percent fructose, and the third group drank water with 10 percent fructose. After eight weeks, researchers tested the rats' blood-glucose levels, testosterone levels, and erectile function.
