Great news for those with ED after prostate surgery!!
New clinical trial results show that stem cells can restore sufficient erectile function to allow previously impotent men to have spontaneous intercourse. This is the first time stem cell therapy has produced patients who have recovered sufficient erectile function to enable intercourse. This is an early trial, further work is ongoing, but it adds to the already extensive body of data world-wide demonstrating the safety and efficacy of the approach.
In recent years several groups have worked to develop stem cell therapy as a cure for erectile dysfunction, but until now the improvements have not been sufficient to allow affected men to achieve full sexual intercourse. Results presented at the European Association of Urology conference in London show that 8 out of 21 have successfully regained sexual function.
Lead researcher, Dr Martha Haahr (Odense University Hospital) said "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. We are now beginning a larger Phase 2 trial to better evaluate its effectiveness and confirm its safety."
Erectile dysfunction affects nearly half of men between the ages of 40 and 70 to some degree. There are several possible causes, including surgery (e.g. prostate surgery), high blood pressure, diabetes, cardiovascular disease and psychological problems. Current remedies, which include medications such as PDE5 inhibitors (such as Viagra and Cialis), injections, which do nothing for the underlying problem and are strictly temporary; or penile implants; all have some disadvantages, so scientists have been searching to find a way which restores natural sexual function. The present work focuses on patients with physical damage, caused by surgery (radical prostatectomy) for prostate cancer. Indeed of the population with ED, this group is the hardest to treat since their ED is due to mainly neurologic damage following the intervention.
The research group, from Odense in Denmark, used stem cells taken from abdominal fat cells via liposuction ,none of the 21 men reported significant side effects over the trial period, or in the following year. After isolating the stem cells, they were injected into the corpus cavernosum area of the penis. The patients were able to be discharged the same day.
Within 6 months of the treatment, 8 out of the 21 patients reported that they had recovered sufficient erectile function to achieve penetrative) sexual activity. This improvement has been maintained for a year, indicating that this treatment may confer long-term benefits. Only those men who were continent were reported to have recovered sexual function (incontinence is also one of the risks of radical prostatectomy prostate surgery).
