There are a lot of scams out there about ED—hundreds of different therapies, mostly without any scientific backing.
At the latest meeting of the American Urological Association, two new studies were presented about two different therapies, one that worked and one that didn’t.
In the first study, published in the Journal of Urology, the researchers performed a study on men with erectile dysfunction (ED) using a special machine that sends shockwaves (soundwaves) to improve blood flow and promote tissue growth. They compared the real treatment with a fake treatment to see whether it worked.
Group 1 received three treatments of 5,000 shocks every 3 weeks, while Group 2 received a sequence of 5,000, 3,000, and 3,000 shocks during the first three weeks and then the same sequence again 3 weeks later.
They used a special type of ultrasound to look at their participants’ penises when they were erect at weeks 20 and 32. Men who received the fake treatment were then told it was fake and were given the real treatment. The scientists then checked their blood flow and looked at the ultrasound images again.
They discovered the following.
-
1. Men who received the real treatment had better blood flow in their penises after the treatment, while those who received the placebo treatment did not.
2. The number of men who had better ultrasound images with healthier penile tissue was also higher in the group that received the real treatment.
3. The men who received the real treatment experienced a slight improvement in sexual function scores.
4. The treatment was safe, with only minimal and temporary discomfort for some men.
From these findings, they concluded that shock wave therapy could improve the health of penis tissue by activating stem cells.
In the second study, also published in the Journal of Urology, a different team of scientists tested platelet-rich plasma (PRP) injections, which are sold as a treatment for ED but haven’t been proven to work. They gave 61 men with mild to moderate ED either two PRP injections or a placebo one month apart.
They then tested their participants’ sexual function using the International Index of Erectile Function questionnaire and checked the amount of blood flow in their penises using ultrasound.
The results showed the following.
-
1. There were no significant differences in the men’s ED scores between the two groups.
2. The PRP injections didn’t work any better than the placebo did in improving blood flow to the penis.
3. A few men had minor side effects, like a bruise or a small bump, but nothing that lasted.
Therefore, while shockwave therapy seems relatively effective at treating ED, injections with platelet-rich plasma seem not to make a difference.
