Research Notes on Erection
An erection occurs when the sponge-like tissue inside the penis fills with blood. They are often caused by sexual arousal but can also occur for no particular reason. Erections either go away on their own, or after an ejaculation occurs.1
Fast Facts:
- Erections often occur during the REM stage of sleep.1
- The penis often produces pre-ejaculate during an erection.2
- Sexual stimulation of an erect penis can lead to ejaculation.3
