Maximum Sexual Performance
In humans, maximum sexual performance, by natural means, is dependent on the male's ability to achieve and maintain an erection. Physical factors directly related to the increase or decline in sexual performance include diabetes, weight gain, testosterone, zinc, elevated insulin levels, low blood flow to the penis, low serotonin levels, brain neurons that misfire, hormonal imbalances, back injuries causing nerve damage, nitric oxide, and exercise.
Exercise, specifically those that build muscle, has been found to greatly increase sexual performance. Body builders can testify to experiencing increased sexual stamina and drive, and now scientists know why. There are three distinctly different reasons:
Studies have shown that exercises that build the quadriceps (the large muscles on the front of the thigh) increase blood flow to the penis by more than 21 percent within a mere half-a-minute. This tremendous increase in the blood supplied to the penis is equal to a sexual rocket-launching.
Exercise also increases growth hormone, which is the youth hormone responsible for libido and sexual stamina during the teen years.
More muscle means more testosterone.
