In a small study in Denmark, researchers restored the function of men’s penises by injecting 20 million stem cells into the base of the organ. Scientists believe that the treatment revitalized the blood vessels and nerves and, unlike Viagra, also appeared to make their penises larger, The Sunday Times reported. Further research is now needed to understand the long-term effects of the treatment, which has so far lasted over a year.
Currently, the research is focused on aiding men whose prostate glands have been removed due to cancer. This procedure can affect the organ’s nerves and blood vessels and cause it to become smaller.
The jab could give hope to the millions of men around the world who struggle with ED. According to the National Institute of Diabetes and Digestive and Kidney Diseases, ED is very common and affects around 30 million men in the U.S. Age as well as certain medical conditions, medications and psychological and emotional issues can make a man more susceptible to ED.
As well as taking medications such as Viagra, current treatments include lifestyle changes, such as quitting smoking, limiting alcohol use and losing weight. Therapy, meanwhile, can tackle the psychological triggers of ED. Some men also use a vacuum device to draw blood to the penis.
