Although other issues such as nerve damage and hormone abnormalities can also lead to erectile dysfunction, the failure of the blood vessels to dilate properly is one of the more common causes, Wittert said. "This is an early abnormality in the pathway to more serious heart disease."
These are not all the possible side effects of VIAGRA. For more information, ask your healthcare provider or pharmacist. .

It’s not an expensive procedure. This therapy cost around $80 to $300 per session of treatment.
The mean profiles of the change from baseline in standing systolic blood pressure in subjects treated with doxazosin in combination with 50 mg VIAGRA or matching placebo are shown in Figure 3.
However, since higher plasma levels may increase the incidence of adverse reactions, a starting dose of 25 mg should be considered in older subjects due to the higher systemic exposure [see DOSAGE AND ADMINISTRATION].

Commercials for drugs to improve “low T,” or testosterone, the male hormone, are now vying for airtime, but they address desire, not performance. "Male hormone is not an approved treatment for erectile dysfunction," notes Bennett. "It may be used to increase desire in men who have low testosterone, but it doesn’t improve blood flow to an erection." A doctor can do a blood test to check you for low testosterone, but it is a rare cause of ED. Hormone therapy with injections, patches, or gels applied to the skin may improve mood and sex drive, but it likely won’t fix any mechanical issues. Also, testosterone drugs should not be used by men with prostate cancer. Side effects include acne, breast enlargement, prostate enlargement, and fluid retention.
One randomized, double-blind, placebo-controlled, crossover, flexible-dose (up to 100 mg) study of patients with erectile dysfunction resulting from spinal cord injury (n=178) was conducted. The changes from baseline in scoring on the two end point questions (frequency of successful penetration during sexual activity and maintenance of erections after penetration) were highly statistically significantly in favor of VIAGRA. On a global improvement question, 83% of patients reported improved erections on VIAGRA versus 12% on placebo. Diary data indicated that on VIAGRA, 59% of attempts at sexual intercourse were successful compared to 13% on placebo.
The major cause of erectile dysfunction is restricted blood flow to the penis because of narrowed blood vessels. In fact, because the vessels in the penis are very small compared to other parts of the body, problems with erectile dysfunction can be a warning sign that other vessels, such as those leading to the heart, may eventually be affected. Diabetes, which also can affect the blood vessels, also is linked to erectile dysfunction.

In addition, N-desmethyl metabolite AUC and Cmax values significantly increased by 200% and 79%, respectively in subjects with severe renal impairment compared to subjects with normal renal function.
The most common cause of ED is a lack of flowing blood to erectile tissue. Plaque and damaged vessels can restrict circulation enough to disrupt function. Typically, symptoms begin with difficulty maintaining an erection before advancing to a complete inability to obtain one.
