A single injection of stem cells could be a long-lasting cure for impotency, scientists have announced.
Results from a trial of men with severe erectile dysfunction shows the stem cell therapy effectively restores spontaneous sexual function.
The findings, presented at the European Association of Urology conference in London, could pave the way for an effective treatment for men who do not respond to Viagra.
Such an approach would be particularly valuable for men made impotent by surgery – including prostate cancer patients – for whom erectile medicines do not often work.+2
But it could also prove useful for men who do not want to have to take pills in order to have sex.
Study leader Dr Martha Haahr, of Odense University Hospital in Denmark, said: ‘It’s very promising. This therapy is regenerating the actual function of the penis, rather than just treating the symptoms.
‘So we could offer just one procedure. It would be attractive for many men, rather than constantly having to take pills and be reminded of their impotence.
‘If it works in larger trials, we will have a safe new treatment that is more effective than Viagra.
‘What we have done establishes that this technique can lead to men recovering a spontaneous erection – in other words, without the use of other medicines, injections, or implants.’
