The results of a study presented at a Sexual Medicine Society of North America meeting suggest that the erectile dysfunction drug Viagra� may help relieve the symptoms that often accompany an enlarged prostate.
The researchers, from Northwestern University, found that Viagra� is effective at relieving the prostate and lower urinary tract symptoms associated with prostate enlargement that often occurs with erectile dysfunction.
Led by Northwestern professor of urology, Kevin V. McVary, the researchers conducted the 12-week study in men aged 45 years and older who were suffering from erectile dysfunction and lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH), an enlargement of the prostate gland that causes an obstruction in the flow of urine.
At the end of the trial period, the participants were assessed for changes in erectile function, lower urinary tract symptoms associated with BPH, quality of life and their maximum urinary flow rate. The results indicate that the men who took Viagra� (at bedtime or before anticipated sexual activity) experienced a significant improvement in erectile function, self-esteem and quality of life, with a decrease in both the irritative and obstructive symptoms of BPH.
The results are important, say the researchers, as more than half of all men 50 years and older have some signs of BPH. Additionally, other studies have shown that more than 70 percent of men with symptoms of BPH also have erectile dysfunction.
