There is a procedure for erectile dysfunction being sold across North America right now, and it costs somewhere between two and four thousand dollars. A Medicare cost-modelling analysis puts a single course at roughly $3,445. It is paid entirely out of pocket, because no insurer covers it and Medicare has no policy for it at all.
Twenty-one randomised controlled trials have studied it. One thousand three hundred and fifty-seven men.
The number of those trials that produced usable evidence on whether the men — or their partners — were more satisfied afterward is zero.
They measured how firm it got. Nobody ever established that anybody’s life got better.
First, what this is not
I want to get this on the record before anything else, because the reflexive read on a piece like this is that I am about to call it a con.
I am not. Low-intensity shockwave therapy does not belong in the same conversation as gas-station honey packs or the blue salt trick. Those are marketing fictions wrapped around either nothing or a hidden prescription drug. This is a therapy with twenty-one randomised controlled trials behind it, summarised in a Cochrane review published in 2025 and abridged in a urology journal this year. That is a real literature. Anyone telling you it is obviously a scam is being just as sloppy as the clinic overselling it, only in the opposite direction.
So the problem is not that nobody has studied this. The problem is what twenty-one trials turned out to be worth.
The premise is correct — and that is exactly why it sells
Here is the part that makes this genuinely difficult, and it deserves to be said generously.
The pitch is right about the biology. An erection is a vascular event. It depends on endothelial function, on nitric oxide availability, on arterial inflow, on blood pressure and insulin sensitivity. A therapy directed at the blood vessels of the penis is directed at the correct organ system, for the correct reason.
That is not the clinic’s argument. That is my argument. Erections are vascular, not age-based. Blood flow is a system issue, not a bedroom issue. The prostate is not failing in isolation. I have been making that case here for a long time, and a man who has absorbed it walks into a consultation already primed to say yes to the first product that speaks the language fluently.
So when he hears we repair the cause instead of masking the symptom, he is hearing a sentence he already believes — because the sentence is true.
A correct mechanism is not a proven product. That distinction is the whole article, and it is worth more than the price of the procedure.
What the review actually found
Stated precisely, because precision is the only thing that separates this from the marketing.
In the short term, the therapy may improve penile rigidity.
In the long term, the effect is small, and Cochrane’s language is that it may not be clinically important. Sit with that phrase for a second, because the long term is the part a man is actually buying. He is not paying $3,445 for a change that shows up on an instrument during a study window. He is paying for something that lasts.
Side effects and discontinuation because of side effects were uncommon in the short term. That is a genuine point in its favour and it should not be buried — physically, this appears to be a low-risk thing to undergo.
And then the rating that governs all of it: the certainty of the evidence was low. On every single outcome. Not because reviewers were fussy, but because of methodological shortcomings inside the trials themselves.
Two further details rarely survive the trip into a consultation room. Several of the included trials were funded by the companies that manufacture the devices. That is not a conspiracy theory — it is a disclosure line printed in the review, and it is ordinary in device research. It is also a reason to read the certainty rating rather than the headline.
The second is stranger. The review’s authors call for trials with standardised protocols. Which means that after twenty-one studies, the field still cannot agree on how many sessions a man should have, at what intensity, over what period.
The clinic quoting you a package has a protocol. The evidence does not.
The column that is empty
This is the finding I keep coming back to, and it is an absence rather than a result.
Across all twenty-one trials and all 1,357 men, no usable evidence was found on patient satisfaction, on partner satisfaction, or on sexual quality of life. Short term or long term. It was not measured in a way that could be pooled and used.
Think about what that means for the man writing the cheque. The entire reason he is in that room is satisfaction — his, and his partner’s. That is the outcome. Rigidity is a proxy for it, and a crude one. Twenty-one trials measured the proxy and left the actual question alone.
That has consequences. It means the only evidence available for the thing he cares about most is the testimonial on the clinic’s wall.
Where it sits officially
The American Urological Association classifies low-intensity shockwave therapy as investigational, with a conditional recommendation and grade C evidence, and points toward restricting it to research settings.
It is not approved by the FDA for treating erectile dysfunction. The devices in clinical use are not cleared for this indication — and clearance for some other use is not approval for this one. That distinction gets blurred constantly in marketing copy, and it is worth knowing the difference before you are the one paying.
No insurer covers it. Medicare has no policy for it. Every dollar is yours.
Why good men read this wrong
Four reasons, and none of them are stupidity.
He is exhausted with management. Every other option on the menu is a workaround he has to repeat forever. A pill an hour before. A device in the moment. Habits sustained for years with no finish line. This one is sold as a course of treatment with an end date. That is not vanity. That is a man tired of maintaining a problem instead of solving it, and that instinct is correct.
The setting says established. It is offered in a clinic, by someone in a coat, at a serious price. Everything in the room signals legitimacy. The word his own urological association uses is investigational.
Volume reads as certainty. Twenty-one trials sounds settled. Twenty-one low-certainty trials is a field that has not settled.
And the price itself is an argument. Men reasonably assume that $3,445 implies evidence proportional to the cost. It does not. Price signals confidence, and confidence is not the same as data.
What the symptom was actually telling him
Here is the part that worries me more than the money.
Erectile change is one of the earliest readouts a man gets on his vascular system. The vessels involved are small, and they tend to register trouble before the larger ones do — before the chest, before the legs, before anything a routine stress test catches. That is why this brand treats it as a signal rather than an embarrassment.
Which means the symptom that sent him to that clinic was carrying information about his whole circulatory system. And the answer he was quoted addresses one branch of it.
If his blood pressure is running uncontrolled — and among American adults being treated for hypertension, only about a quarter are actually at goal — that continues regardless of what happens in the treatment room. If visceral fat is driving insulin resistance, that continues. If he is sleeping five broken hours, that continues. That creates biological drag, and no device applied to one artery touches any of it.
He came in with a system-wide signal and got quoted for a local repair.
The four numbers that cost nothing
Before several thousand uninsured dollars go toward one branch of the system, there is information available this week for free that describes the whole thing.
Blood pressure, at home, across seven days. Morning and evening, written down. Not one reading taken in a clinic while you are annoyed about parking. A cuff on the kitchen counter, not in a drawer.
Waist at the navel. Not trouser size, not scale weight. A tape measure at the belly button tells you more about your metabolic situation than the number on the scale does.
Sleep duration, counted honestly. Time actually asleep, for a week. Most men overestimate this by an hour or more.
Fasting glucose and A1c from ordinary bloodwork, which your doctor can run without any of this being a difficult conversation.
Those four describe the system the erection is reporting on. They cost nothing, and they answer back.
The inputs that pay
Load-bearing training, two or three times a week. Muscle is metabolic insurance, and it is the lever most men over forty skip because it is slow and unglamorous.
Nitrate-rich vegetables — beets, arugula, leafy greens — to support the nitric oxide pathway. Dark berries. Fatty fish. Protein at every meal rather than stacked into dinner. This is nutritional support for blood flow, not medicine, and it is not a substitute for anything a doctor has prescribed you.
Sleep addressed before any supplement is considered. Alcohol counted honestly rather than estimated generously.
And the appointment worth making first: erectile change deserves a cardiovascular and metabolic workup, not just a treatment quote. If you take one thing from this article, take that.
What I am not saying
I am not saying shockwave therapy does not work. The Cochrane review does not say that, and if I said it I would be committing exactly the error I have spent this article describing — asserting a conclusion the evidence does not carry.
Low certainty means we do not know. It does not mean no.
A man who has worked the free levers, had the real workup, and still wants to try this — with his eyes open, knowing it is investigational, knowing the certainty is low, knowing nobody measured satisfaction, knowing no insurer covers it — is making a legitimate decision about his own money. That is his call and I am not going to pretend otherwise. Stop with the excuses is a sentence I use often, and it does not apply to a man who has done the work and made an informed choice.
What I am saying is about sequence, and about price.
The instinct was right
A man looking at that quote has already decided something important. He decided he wants the cause addressed rather than the symptom managed. He decided he is done borrowing an effect and wants to build one. That is discipline over dependency, root cause over hype — this brand’s own spine, arriving in a clinic waiting room under someone else’s letterhead.
He is right about the instinct. He is wrong about the price of acting on it.
Spend it where the evidence is strongest and the cost is lowest. Get the four numbers this week. Move the load. Fix the sleep. Measure the waist. Then decide what is left worth buying.
The body keeps score. Let’s get healthy.
