Does Taking Viagra Make a Man More Virile?
It might. A surprising new area of research is
whether taking a small dose of Viagra every night works as a preventative
to stave off impotence, just as people can take an aspirin a day
to prevent heart attack.
Though you wouldn't think you'd get much out
of Viagra while you're sleeping, it turns out that nighttime erections
-- most men get three or four every night -- are crucial to maintaining
potency. Because most men don't have several erections during
the day, the nocturnal erection, which allows blood and oxygen
to flow to the genitals, is nature's way of keeping the penis
in working order. The theory is that anything that increases the
intensity and duration of nighttime erections is good for long-term
potency.
But don't you need a sexual stimulus for Viagra
to work? You do, and the likely trigger for nighttime erections,
rapid-eye-movement sleep, is said to be the strongest sexual stimulus
a man can experience. The brain shuts down all other activity
to the penis and the level of adrenaline, which interferes with
erections, plummets.
An Italian study of 44 men gave half the men
50 milligrams of Viagra before they went to sleep. The men averaged
39 years of age and didn't have erectile dysfunction. Those who
took Viagra had significantly longer and more rigid nighttime
erections than the men taking a placebo.
Irwin Goldstein, a noted Boston urologist, says
about 400 of his patients are using 25 mg of Viagra each night
as a preventative measure. "Men say, 'I'm potent. I don't
want to become impotent. Is there something I can do?' "
says Dr. Goldstein. "It's a very simple strategy for preserving
sexual health."
But while it makes sense in theory, whether nighttime
Viagra use can prevent impotence is far from proven. Pfizer says
it's studying whether nighttime Viagra use can help improve sexual
function in patients who have had prostate surgery but it won't
present the results until early next year.
Meanwhile, it's worth noting that the best way
to prevent impotence is to keep your veins from clogging up in
the first place. Don't smoke, eat healthy foods, lose weight and
lower your cholesterol.
