How Does Viagra Help With ED?

Viagra is likely the most written about drug in the last 25 years, and for a good reason. This medication gave the baby boomers from the 60s and 70s, plus many other men, a lifeline if they developed erectile dysfunction. But how exactly does Viagra help men with ED?

What Causes Erectile Dysfunction?

Erectile dysfunction is the persistent inability to achieve and then maintain an erection firm enough for sexual intercourse. It is a frustrating and depressing condition for millions of men.

There are a myriad of reasons why a man may have erectile dysfunction. There may be emotional, psychological, or physical reasons.  

How Does Viagra Help?

The little blue pill, Viagra, helps ED with one of the physical issues. Viagra (or its generic namesake Sildenafil) increases blood flow to the penis which is one of the necessary requirements for an erection. 

When a man is aroused, the body releases nitric oxide, a molecule that triggers an erection. However, a protein or enzyme known as PDE5 intervenes and blocks the messages to achieve the erection. Viagra is a PDE5 Inhibitor, so it obstructs the enzyme and allows the erection to occur.

It improves firmness, frequency, and maintenance, and it is most effective for mild to moderate ED.

Viagra is also effective for ED caused by diabetes, spinal cord injuries, and prostate surgery.
