Viagra (sildenafil) is a drug that is taken by men with erectile dysfunction (ED) to improve sexual performance. It works by increasing blood flow to the penis to help a man get and keep an erection. But, it has also been linked to erectile dysfunction. In a study published in the British Medical Journal (BMJ) in April 2017, researchers found that men who took Viagra for at least four hours before sexual activity were also more likely to have ED. In another study published in the BMJ in September 2015, a team of researchers looked at 30,000 men in three European cities, including Austria, Belgium, Germany, and Spain. All were taking sildenafil (the generic version of Viagra). The authors concluded: “Men with ED who take Viagra for at least four hours before sexual activity are more likely to have ED.” The authors also stated that their study “is the first to evaluate the effects of Viagra on the sexual functioning of men with ED using a standardized questionnaire to assess erectile dysfunction.” In a separate study published in the British Medical Journal in October 2016, the researchers looked at a large sample of men with ED and reported that those taking Viagra for at least four hours before sexual activity were “more likely to have ED.” The researchers added that the study was “not the first to evaluate the effects of Viagra on erectile dysfunction, and the results should be interpreted cautiously.” However, the researchers concluded: “In general, it is recommended that men taking Viagra for at least four hours before sexual activity should discuss the potential risks and benefits of taking this medication with their healthcare provider.”
