How An Erection Works

3/4

A successful erection involves several parts of the body working together: the brain, blood vessels, nerves, and certain hormones. Sexual stimulation resulting from various erogenous thoughts or stimuli or local genital contact triggers the erectile process. The brain and nerves of the nervous system course in the pelvic region to the genitalia and direct chemical messages that result in penile erection. 

The process importantly involves blood flow to the penis. The erectile tissue and blood vessels supplying the penis open up and allow blood entry to cause engorgement and rigidity of the penis under the control of chemical signals. Depending upon the level of stimulation, the chemical signals determine whether the penis is in its flaccid or erect state.
