There are many potential causes of erectile dysfunction or ED and a host of ideas about how to treat it. Some approaches to erectile dysfunction are evidence-based and even have been rigorously proven such as the drugs Viagra and Cialis, which increase blood flow to the p3enis. Depending on the causes of the dysfunction, these drugs may be helpful for many people, but they are also very expensive and not panaceas.
Other approaches to erectile dysfunction are not proven at all and also pose major risks, but still are being marketed on a for-profit basis any way. Two such unproven approaches can broadly be classified as injections of supposed “stem cells” and of platelet-rich plasma (PRP). The stem cell injections are usually of fat stem cells in the form of the non-FDA approved drug product called stromal vascular fraction (SVF).
I’ve written before about how some clinics are claiming that stem cell-related approaches can effectively treat ED, while others are marketing stem cells to increase p3enis size or somehow make v@gin@s “younger” or somehow otherwise enhance secual function. But to my knowledge there are no strong clinical studies (using placebos and blinding) supporting these approaches. You can imagine that injections of unproven biologic materials into p3enises or v@gin@s pose risks.
An organization called the Sexual Medicine Society of North America (SMSNA) recently issued a position statement on the use of stem cells, PRP, and shockwave therapy for ED. While I don’t agree with everything in this SMSNA statement, there are some helpful recommendations in it. The key take-home message is this concluding portion:
“Thus, given the current lack of regulatory agency approval for any restorative (regenerative) therapies for the treatment of ED and until such time as approval is granted, SMSNA believes that the use of shock waves or stem cells or platelet rich plasma is experimental and should be conducted under research protocols in compliance with Institutional Review Board approval. Patients considering such therapies should be fully informed and consented regarding the potential benefits and risks. Finally, the SMSNA advocates that patients involved in these clinical trials should not incur more than basic research costs for their participation.”
In other words, it’s not okay to sell regenerative therapies for ED for a profit. I’d go substantially farther and say that in addition these “treatments” should not be used outside of a standard IND-based clinical trial process. The same goes for other regenerative secual “therapies” that are not based on rigorous science.
