Best sites for Penile Injection

What is penile injection?

Penile injection is a therapy technique that helps you get an erection if you are having Erectile dysfunction(ED). The process involves directly injecting the medication into the erectile tissue in the penis which helps in erection by opening the blood vessels in your penis.  The medication increases blood flow and causes the blood vessels in the penis to widen and dilate. It causes erections that last up to 60 minutes. This might sound a bit odd to inject directly into your penis but this is one of the best treatments to cure ED.
