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, or penile implants; all have some disadvantages, so scientists have been searching to find a way which restores natural sexual function. ...

The research group, from Odense in Denmark, used stem cells taken from abdominal fat cells via liposuction (under a general anaesthetic): 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).

Dr Martha Haahr said: “We are the first to use a man’s own fat stem cells as a treatment for erectile dysfunction in a clinical trial. The technique has been trialed in animal work, but this is the first time stem cell therapy has allowed patients to recover sufficient erectile function to enable intercourse.


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, which was primarily addressing safety and dosage (a Phase 1 trial), so the results need to be interpreted accordingly.
