The Effects of Viagra on The Body Do Not Use It
Viagra is a brand name for the generic drug sildenafil. It’s a phosphodiesterase type 5 (PDE-5) inhibitor. PDE-5 is an enzyme that can stop you from having an erection.
This medication is used to treat erectile dysfunction (ED). While it helps you temporarily maintain an erection so you can have sex, it does not cure ED. Also, it does not affect sexual desire. You still need mental or physical stimulation to get an erection.
1. Circulatory System.
Beginning with arousal signals from your brain, it takes a finely choreographed series of events to produce an erection. And it all hinges on good blood flow to the penis.
Within the penis are two chambers called the corpora cavernosa. Nitric oxide (NO) is released in the chambers during sexual stimulation. NO activates an enzyme called guanylate cyclase. That increases levels of cyclic guanosine monophosphate (cGMP), which causes muscles to relax.
The chambers also contain a network of blood vessels. When those blood vessels relax and widen, blood rushes in. The resulting pressure is what causes an erection.
PDE-5 can dampen the effect of cGMP. Viagra works by inhibiting PDE-5.
Viagra is rapidly absorbed into the bloodstream. Maximum concentrations are reached within an hour.
One of the more common side effects is flushing or redness.
This medication can cause a decrease in blood pressure, particularly one to two hours after taking it. If you already have low blood pressure, discuss the pros and cons of Viagra with your doctor.
2. Reproductive System.
Viagra can be quite effective, but it’s no magic pill. It does nothing for your libido. You still need some kind of stimulation to get an erection.
The effects of Viagra usually last about four hours, though it may last longer for some men. A rare, but serious side effect, is priapism. That’s when you get an erection that lasts for a long period of time. It can become quite painful. If you have an erection that lasts for more than four hours, seek immediate medical attention.
You should also be wary of PDE-5 inhibitors if you have an anatomical abnormality of the penis. If you have Peyronie’s disease, your doctor may advise against taking Viagra.
Viagra is a temporary fix and does not cure ED. It offers no protection from sexually transmitted diseases.
3. Central Nervous System.
Viagra helps to improve blood flow to the penis, but your brain is still your most valuable sex organ. Viagra won’t work if you’re not in the mood.
Some potential side effects of Viagra are a headache and runny or blocked nose. Some men feel lightheaded or dizzy. Rarely, Viagra can cause fainting. Some men taking PDE-5 inhibitors report back or muscle pain.
It’s not common, but some men experience ringing in the ears, hearing loss, or vision loss after taking PDE-5 inhibitors. Avoid PDE-5 inhibitors if you have a history of an eye condition called non-arteritic anterior ischaemic optic neuropathy.
If you have hearing or vision loss while taking Viagra, seek immediate medical help.

Have you heard about Mario Volpstein's approach by any chance? It's dangerously effective. Doesn’t matter what you've tried, you can get massive, rock hard erections and give your partner all sorts of pleasures by using some silly techniques. Look for it in google to see what I mean.
This was great, been searching for "free secrets to lasting longer in bed" for a while now, and I think this has helped. Ever heard of - Taayichool Longer Prepotence - (search on google ) ? Ive heard some amazing things about it and my neighbour got cool success with it.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
