An international team has successfully tested the new technique – which involves tiny objects called nanoparticles – on laboratory rodents and believe it could also be used to help humans, 'The Daily Telegraph' reported.

According to the scientists, under the new therapy, nanoparticles that release the anti-erectile chemical nitric oxide are rubbed on the problem area, and absorbed directly into the skin.

In fact, of the seven rats treated by the team, led by the Albert Einstein College of Medicine, New York, five showed signs of arousal, the findings of which are presented at the American Urological Association.

"This is a very interesting concept which has potential to impact treatment of many conditions including erectile dysfunction if it can be translated from the animal lab to clinical practice," said Ira D Sharlip of the AUA.
