Injections and Intraurethral Suppositories

Injection therapy requires the man to use a small needle to inject medication directly into the penis. The medicine relaxes the blood vessels and allows for increased blood flow into the penis, creating an erection. Injections are effective, fast-acting treatments because the medicine is delivered directly into the penis.injection_therapy_1

Intraurethral Suppositories

The intraurethral suppository contains a medication that works like the injection.
