What is a Penile Injection?

Penile injections are injections of medication or solution into the penis for diagnostic or therapeutic purposes. Penile injections may be used for the following conditions and procedures:

  • Aspiration and irrigation, which is done to reduce pain and swelling due to priapism (prolonged erection). A needle removes blood from the penis, which is then injected with solution (irrigated) to remove blood clots.
  • Cavernosography, which is a diagnostic penis imaging test that involves the injection of a contrast dye into the penis. Cavernosograms are often used to confirm diagnoses of conditions, such as erectile dysfunction.
  • Erectile dysfunction, which can be treated by injection if oral medications fail to work. Penile injections for erectile dysfunction must first be attempted in a doctor's office to test for side effects. If there are none, you will be taught to perform the injection yourself at home. The injection must be done each time you wish to achieve an erection.
  • Peyronie's disease, which involves a buildup of scar tissue in the penis. A penile injection for Peyronie's disease is used to treat pain rather than cure the disease.

Complications associated with penile injections include pain, swelling, bruising, prolonged erections, and scar tissue buildup. If penile injection therapy is unsuccessful, surgical intervention may be necessary.
