Viagra improves circulation to the penis by inhibiting the action of an enzyme called PDE-5. Less PDE-5 means more of a substance called cGMP that improves blood flow.
Viagra has been the number one treatment for erection health for more than a decade. In fact, it was a revolutionary approach to erection problems that has led the way in creating new treatments. But what does Viagra actually do, inside your body?
To understand that, we have to first understand how the penis works. As you experience some form of stimulation, blood vessels in the groin expand and blood fills sponge-like areas in the penis, enlarging it and pointing it upwards. Erection issues, at its most basic level, is simply blood not flowing quickly enough to the penis, due to blood vessels being too narrow. ED has many possible factors, including stress and diet, but Viagra goes straight to the source.
Viagra is a vasodilator, or a drug that opens up the blood vessels. Specifically, Viagra targets an enzyme called cGMP-specific phosphodiesterase type 5, or PDE5, for short. “cGMP” is cyclic guanosine monophosphate, which the body uses to relax smooth muscle tissues, such as the smooth muscle tissue found in the penis.
PDE5 breaks down cGMP; that’s its job. However, if you have a combination of factors preventing blood flow to areas where you’d really like it to be, namely, your penis, this becomes a problem. The PDE5 is just doing what it’s told, and it’s not going to stop however many Playboys you read.
Viagra works by improving circulation to the penis.
This is where Viagra comes in. Viagra introduced nitrous oxide to the party. Nitrous oxide bonds with the PDE5 before it can break down the cGMP, allowing it to relax the smooth muscle tissue and give you an erection. This is why one of the possible side effects of Viagra is priapism, or an erection that lasts more than four hours; if you have an excess of cGMP and lower levels of PDE5 in the first place, if you take out the PDE5, your cGMP will run wild.
It’s worth noting that just because the way is clear for an erection, though, doesn’t mean you automatically get one. There needs to be some sort of stimulation to obtain an erection; Viagra only lays the chemical groundwork. So, really, it only gets you halfway there: the rest is up to you.
