But what was it about cycling that led particularly to erectile dysfunction? Goldstein's study hadn't uncovered a cause, but another study done at the University of California, San Diego, offered an explanation. The study -- done in conjunction with Serfas, a bicycle accessory company in Lake Forest, Calif. -- found that the rub lies not in cycling itself but in the seats.
In one randomized, double-blind, placebo-controlled, multi-center clinical trial conducted in China (5), 157 ED patients aged 26 to 75 with various etiologies (psychogenic, organic, and a combination of both), had an average ED history of 5 years. They all received treatment of Befar or a placebo for 4 weeks. After the 4-week period, the Befar patients improved their ability to have and maintain their erections by 68%. The same patients also improved the frequency and strength of their erections by 75%.

Medications can be injected directly into the corpora cavernosa to attain and maintain erections. Medications such as papaverine hydrochloride, phentolamine, and prostaglandin E1 can be used alone or in combinations to attain erections.

Even though such injections can be effective, they are not widely used because the injections are painful, there may be scarring of the penis, and there is a risk of developing priapism.

Cialis has been shown in clinical trials to stay in the body longer than the other selective enzyme inhibitors. It promotes erection within 30 minutes and enhances the ability to achieve erection for up to 36 hours.
In a second study based in Italy, researchers from four medical centers recruited 291 men who had both type-2 diabetes and silent CHD discovered by stress testing and confirmed by x-ray angiography. Of these subjects, 118 had erectile dysfunction at the beginning of the study. The study subjects were followed for four years with all instances of major adverse coronary events (MACE) documented. Results of the study indicated that those who had erectile dysfunction at the beginning of the study were twice as likely to experience a major adverse coronary event. This particular study also happened to conclude that taking a cholesterol-lowering statin drug reduced the risk for an adverse major coronary event by one third.
