Penile Injections

 

 

Overview

Penile injection therapy for ED was first introduced in the early 1980's, and has been used by hundreds of thousands of men. It was more widely used before the introduction of medications such as Viagra, but it is still used by many men today. This page discusses the pros and cons of penile injection therapy.

How is penile injection therapy done?

The medication is injected directly into the inner part of the penis through a very small "insulin-style" needle. The medication is not injected under the skin, but must be injected into the inner part of the penis that fills with blood during an erection. The injection can be performed on either side of the penis, and the medication will spread throughout the entire penis. A firm erection develops in 10-15 minutes and lasts 30-60 minutes. The amount that needs to be injected to produce a strong erection varies from person to person, and patients inject the smallest volume necessary to give an adequare erection. The medication can produce an erection even if a man is not aroused, but sexual arousal assists the medication in producing a good erection.
