Scientists have developed a new treatment for those men who do not respond well to pills such as Viagra. The so-called Maxi-K gene therapy represents a gene transfer that improves erectile dysfunction. This new technology has the potential to offer men with erectile dysfunction long-term improvement.

Medications such as Viagra and Cialis don't work well in 40% of all cases and the market is quite large. Research results showed that both urologists and patients were ready to switch to prescribing and receiving the gene transfer treatment.

Trial testing done on 11 men showed that the gene transfer was safe and that it had restorative effects. Four different doses were tried during the trial and men who received the highest dose showed improvement for up to six months. Researchers said that two doses a year would be enough for most men to maintain their normal sexual function.

Study participants were followed by the following two years and none of the men who had received the gene therapy reported any abnormalities after the gene transfer. The procedure was safe, and no adverse effects were seen.

Another trial tested the gene therapy on four monkeys. They were first fed a high-fat diet in order to reduce their sex drive. After receiving a Maxi-K gene transfer, they became friskier; the number of partial and full erections increased about fivefold, the frequency of ejaculations as well as socialization increased too.
The gene transfer had effect on how the male monkeys behaved with female monkeys. After receiving the gene transfer and regaining sexual function, the males felt better about themselves.
Scientists are hoping to have the drug on the market within two years.
