How An Erection Is Formed

Hormones, blood vessels, nerves, and muscles must all work together to cause an erection. Your brain starts an erection by sending nerve signals to the penis when it senses sexual stimulation. Touch may cause this arousal. Other triggers may be things you see or hear, or sexual thoughts or dreams.


Your brain starts an erection by sending nerve signals to the penis.

The nerve signals cause the muscles in the penis to relax and let blood flow into the spongy tissue in the penis. Blood collects in this tissue like water filling a sponge. The penis becomes larger and firmer, like an inflated balloon. The veins then get shut off to keep blood from flowing out.

After climax or after the sexual arousal has passed, the veins open back up and blood flows back into the body.
