Symptoms
By Mayo Clinic staffPriapism causes abnormally persistent erections. Priapism symptoms vary somewhat depending on the type of priapism.
Ischemic priapism
Ischemic, or low-flow, priapism is the result of blood not being able to leave the penis. It's the most common type of priapism. Signs and symptoms include:
- Unwanted erection lasting more than four hours
- Rigid penile shaft, but usually soft tip of penis (glans)
- Erection not related to sexual stimulation or persistent after stimulation
- Usually painful or tender penis
Nonischemic priapism
Nonischemic, or high-flow, priapism occurs when too much blood flows into the penis. Signs and symptoms include:
- Unwanted erection lasting at least four hours
- Erect but not rigid penile shaft
- Erection not related to sexual stimulation or persistent after stimulation
- Usually painless
Stuttering priapism
Another type of ischemic priapism, stuttering, or recurring, priapism occurs off and on. A stuttering erection is usually painful and generally lasts several hours.
When to see a doctor
Go to the emergency room if you have an erection lasting longer than four hours.
If you experience a painful, persistent erection that resolves on its own in less than four hours, see your doctor, because you may need treatment to prevent further episodes.
