Sickle cell disease Priapism (1570)

Key points below

What is Priapism?

Priapism is a long and often painful erection of the penis. This is not a normal erection. Priapism occurs when the red blood cells sickle and stick together in the penis. The blood is trapped and doesn’t flow back out.

What are the symptoms?

There are 3 types of priapism. The symptoms for each type include:

1. Prolonged.  This is a painful erection that lasts more than 30 minutes.

2. Stuttering.  This is a painful erection that may come and go over several hours.

An erection that is painful and goes on for 30 minutes, needs to be treated.  Go to the emergency room.

3. Persistent.  This is an erection that may last a long time.  Normally there is no pain with this type.
If there is a long-lasting erection, but there is no pain call the Sickle Cell Center.  They can help you figure out what to do.
