Viagra is the 'Fountain of Hot Sex' for many aging Romeos, but it often comes at a price. Common side effects include headache, sinus congestion, blurred vision, upset stomach and lightheadedness. Scientists from the Albert Einstein College of Medicine at Yeshiva University are working on an erection-promoting cream that has fewer side effects than Viagra, and works in two to three minutes instead of 30-45 minutes.

The cream will target the penis instead of affecting all the blood vessels in the body. The cream contains mini-pills called nanoparticles that deliver drugs directly to target tissues. The nanoparticles contain nitric oxide or nitric oxide plus Viagra that increase blood flow in the penis and promote erections. The cream has only been tested in animals, so don't expect it at the local pharmacy anytime soon. (Journal Sexual Medicine, in press; published online September 18, 2009)
