Sildenafil citrate works by increasing the amount of blood that is produced by the penis.
“If you take Viagra, it is very important to take it as directed by your doctor or health care provider,” Dr. Jane Thompson, a urologist with the Royal College of Surgeons, said in the article.

This study was published in theJournal of the American Medical Association.
