Tenuto 2 vs. RX Sleeve: Which Is Right for Your ED in 2026?

The choice between the Tenuto 2 and an RX Sleeve comes down to one question. Can you still get some kind of erection on your own? The Tenuto 2 is a vibrating ring that works with the erection your body produces, so it needs something to build on. An RX Sleeve is the structure itself. It is a hollow silicone sleeve, held in place by our patented The Grip™ harness, so penetration does not depend on getting hard. If pills, injections, pumps, or rings have stopped producing an erection you can actually use, that is the situation RX Sleeve is made for.

Somewhere between 30 and 50 million men in the United States live with erectile dysfunction, and most of the men who write to us have already tried several treatments. About 80% of our customers are over 60, and a good number of them contact us after seeing the Tenuto 2 advertised or hearing about it from a urologist. They want to know whether it will do anything for them before they spend the money. That is a fair question, and the honest answer depends entirely on how much erectile response you have left. Both devices are worn on the outside of the body, and both are sold without a prescription, but they are built on opposite assumptions about what your body can still do.

What is the Tenuto 2 and how does it work?

The Tenuto 2 is a wearable vibrating ring for men, made by the UK company MysteryVibe, which now trades under the name MV.Health. It combines vibration with light constriction at the base of the penis. The shaft goes through a central opening. A bridge extends downward with elastic wings that loop around the scrotum, and those wings hold a vibrating section against the perineum, the area between the scrotum and the anus.

Inside the flexible silicone body are four small motors. Three sit at the front, along the shaft, where the manufacturer says they stimulate the man and also reach his partner during intercourse. The fourth sits in the section against the perineum, where it stimulates the pelvic floor muscles. You will see older articles that say six motors. Six was the original 2018 Tenuto. When the redesigned Tenuto 2 came out in 2022, the count dropped to four.

The device runs eight preset vibration patterns at 16 intensity levels, controlled either by buttons on the device or through a phone app on iOS and Android that a partner can also operate. It is waterproof and charges through recessed pins. It sells in the low hundreds of dollars, with promotions common, and comes with a 24 month warranty when bought from the manufacturer.

The Tenuto 2 works as a constriction ring, which means it slows blood from draining back out of the penis once blood is already there. The wings are shaped to put pressure along the top and sides, where the main veins run, and to stay off the underside, which is why it does not block ejaculation and does not have to come off before you finish. That design is a real improvement over a plain rubber band. It does not change the underlying requirement. A constriction device has nothing to hold in unless your body can fill the tissue first.

What does the research on the Tenuto 2 actually show?

The Tenuto 2 is marketed as clinically proven to reduce ED by 2x. That figure is real, and it is also much narrower than it sounds. It traces back to two small studies presented as conference abstracts in The Journal of Sexual Medicine, not to a large controlled trial.

The first followed seven men with an average age of 36 whose ED was psychogenic, meaning anxiety-driven rather than caused by damaged nerves or blood vessels. Their scores on a standard erectile function questionnaire went from 11 up to 20 over eight weeks, which is a genuine improvement for that group. The men were young and none had nerve or vascular damage. The authors also disclosed that they were consultants, employees, or shareholders in the company. The second study was a report on a single 59 year old patient after colorectal cancer surgery, whose score rose from 7 to 15. Doubling from 7 to 15 is progress, and 15 still falls inside the range that counts as moderate ED. He did not get back to unassisted penetration.

The study closest to the men we hear from was presented in 2025 and looked at 16 men, average age 62, using the Tenuto 2 daily after robotic prostate removal. All 16 were also using a vacuum pump every day and taking 5 mg of tadalafil every day for at least three months. There was no comparison group. Daily tadalafil and daily vacuum therapy are both established parts of penile rehabilitation on their own, so there is no way to separate out what the vibration contributed. The trial was funded by the manufacturer. Every participant also had mild ED to begin with and had nerve-sparing surgery. Fifteen of the 16 found the device easy to use, and four chose to drop the vacuum pump and keep using vibration alone, which suggests they found it more comfortable to live with than pumping every day.

Read fairly, the evidence supports the Tenuto 2 for men who still have working nerves and blood flow, and it does not reach men whose erectile response is already gone. Professional guidelines sit in the same place. Neither the American Urological Association nor its European counterpart lists vibrating rings among the recognized treatments for ED, which are oral medications, vacuum erection devices, injections, urethral suppositories, and surgical implants. Vibration appears in those guidelines mainly around ejaculation problems and sensory testing.

How does an RX Sleeve work without an erection?

An RX Sleeve takes the opposite approach. Instead of trying to produce an erection, it supplies the rigidity from the outside. The sleeve is a hollow silicone shaft that your penis sits inside, whether it is soft, partly firm, or fully erect. All the structure needed for penetration comes from the silicone, so nothing about it depends on blood flow or nerve signals. This is what urologists call an external penile prosthesis, and it has been written up in the medical literature as a non-invasive option for men who have run out of restorative treatments and do not want surgery. We cover the basics in our guide to what a penis sleeve is.

The harness is the part that keeps everything where it belongs. Thrusting pushes back against the sleeve, and anything that relies on internal firmness to stay put will shift or slide off. The Grip™, our patented non-pinch harness, anchors the base of the sleeve against your body using a stretchable silicone loop and a 60 inch soft paracord belt. It comes installed on every sleeve. Because the harness does the holding, your own firmness has no bearing on whether the sleeve stays where it should. If you want the step-by-step, we cover it in our guide on how to use a penis sleeve.

We make sleeves in two firmnesses, and picking the right one is the main decision:

• Firm is for men who cannot get or hold an erection at all. The denser silicone holds its shape and resists buckling during penetration even around a fully soft penis.
• Soft is for men who still get partly hard and want added girth, length, and staying power. It has more give and reads as more natural to the touch.

For a partial erection that does not fill the length of the sleeve, the Adjustable Inner Rod fills the space between the head of your penis and the closed end so there is no air gap. Our Ring Kit is four platinum-cured silicone retention rings that help a Soft sleeve stay snug. Neither of these vibrates. They are fit and retention accessories, and they are not doing the same job as a Tenuto 2.

Men and their partners ask about realism first, so that is where we spend the most effort. Every sleeve is handmade in the USA from 100% platinum-cured silicone, certified skin safe by an independent lab to the OECD TG 439 standard. It is non-porous, hypoallergenic, and warms to body temperature, with sculpted detail and a lifelike firmness. There are three skin tones to choose from, Caramel, Coco, and Vanilla. Full customization is available, up to a sleeve built to your own specifications.

The regulatory labels on both products get used loosely, so here is what they actually mean. RX Sleeve is FDA-listed as a Class II External Penile Rigidity Device, the FDA category that covers vacuum pumps, constriction rings, and penile splints. MV.Health describes the Tenuto 2 as an FDA-registered Class II device listed as a genital vibrator for therapeutic use, which is a different category. Both categories are Class II and both are exempt from premarket review, so in each case the manufacturer registers with the FDA and lists the device. Neither product is FDA-approved or FDA-cleared, and no product in either category is.

Tenuto 2 vs. RX Sleeve comparison

Which device fits your situation?

The right choice depends less on the specs than on what your body can still do.

You get partly hard and lose it during sex. Either device can work here. The Tenuto 2 is designed for exactly this, holding what you have and adding stimulation for both of you. A Soft RX Sleeve is the other route, and it removes the timing pressure completely, because the sleeve does not soften. Men who have already tried rings and found they lose firmness anyway tend to do better with the sleeve.

You had nerve-sparing prostate surgery and you are still in recovery. The nerves may still respond to rehabilitation during this period, so vibration therapy fits the picture alongside whatever your urologist has you on. Many men use a sleeve during the same stretch so their sex life does not go on hold while they wait.

You had non-nerve-sparing surgery, or the nerves did not come back. A constriction device has little to work with here. The nerve pathways that tell the penis to fill with blood are gone, so vibration has nothing to signal. This is the clearest case for a Firm sleeve, because it does not ask your body for anything.

Pills stopped working or never worked. Oral ED medications work for roughly 60% to 70% of men overall, which means 30% to 35% do not respond at all. Response is far lower in the groups these pills struggle with most, including men whose nerves were cut during prostate surgery and men with severe diabetic neuropathy, because the drugs depend on a nerve signaling pathway that has to be intact to work. If maximum doses do nothing for you, there is usually not enough blood flow for a ring to trap either. A Firm sleeve is the practical answer.

You had radiation for prostate or pelvic cancer. Erectile function tends to fade gradually after radiation rather than dropping off right away, as the small blood vessels and tissue scar over. Prospective studies put ED rates at 60% to 70% after external-beam radiotherapy, with randomized trials reporting 30% to 40%, and the rates after brachytherapy are similar. As that damage progresses, devices that depend on blood flow stop delivering. A sleeve keeps working.

You had an implant removed. With the implant gone, there is no internal structure and typically no natural erection either. A Firm sleeve replaces the structure from the outside without another operation.

You have long-standing diabetes or vascular disease. Years of high blood sugar and hardened arteries damage the small vessels and the muscle tissue inside the penis. Two things go wrong at once: not enough blood gets in, and what gets in does not stay. Constriction only addresses the second problem, so a ring usually does not produce much. A Firm sleeve does not depend on either one.

Where each device fits after prostate surgery

Both products are marketed to men after prostate surgery, and both belong in that conversation at different points.

In the first year or two, the goal is usually rehabilitation. Reported ED rates after radical prostatectomy run from 25% to 75%, and when potency does come back, it usually takes 12 to 24 months and often involves daily medication, vacuum therapy, or both. That is the window where a device like the Tenuto 2 makes sense as one part of a program your urologist is running.

For a lot of men, that recovery never comes. Across most studies, only 20% to 25% of men regain erections firm enough for sex without help. Non-nerve-sparing surgery lowers those odds further, because the nerve pathways the recovery depends on are gone. At that point the choice is between a surgical implant and something you wear, and that is where most of our customers arrive. A survey of 147 men with ED, average age 60, found that willingness to try an external prosthesis went up as men were given more information about it, and that men clearly preferred the device described in clinical terms rather than as a novelty. That matches what we see.

Using a sleeve does take a conversation with your partner and some willingness to do things differently. The same research found that flexibility about how sex has to happen was the one factor tied to whether a man was open to trying the device in the first place. Couples who talk about it first do fine.

What does each one do for your partner?

The Tenuto 2 adds vibration for both people. The motors at the front of the device make contact with your partner during penetration, and the app lets her control the patterns. That is something a sleeve does not do.

An RX Sleeve gives your partner penetration that does not stop early or fade. You choose the length and girth, so you can match what you had or add to it, and the sculpted silicone warms to body temperature. For couples who have gone months or years without intercourse, that is usually what they want back first. The other part, which comes up in almost every letter we get, is that the pressure is gone. Neither of you spends the evening waiting to find out whether it will work.

One concern we hear constantly is whether the man feels anything. Richard Wassersug and Erik Wibowo, who reviewed these devices for men recovering from prostate cancer treatment, pushed back on the assumption that they deaden sensation. They describe how several sources of stimulation add up during intercourse, and how a sleeve fitted properly to the penis carries tactile sensation well enough that men with severe ED can stay aroused and reach orgasm. Sensation varies by person and by condition, and we tell people that plainly.

Can you use the Tenuto 2 and a penis sleeve together?

No. We looked for any clinical protocol supporting it and found none, and the reasons are mechanical. The Tenuto 2 is a semi-rigid body holding four motors, a battery, and perineal wings. Putting a sleeve over it stops the sleeve from seating flat against your body, which is what keeps it stable during penetration. You also end up with two devices compressing the same tissue at once, which raises the risk of bruising, numbness, and pressure injury. The two are also built for opposite purposes. One works on an erection you already have, and the other supplies the firmness you cannot produce, so stacking them adds complications without adding anything useful.

A vacuum pump and a sleeve do work together. Pumps have a well-known weakness called the hinge effect, which happens because the pump draws blood into the outer part of the shaft while the base stays soft, so the erection pivots at the bottom and makes penetration awkward. Pumping first, transferring the tension ring to the base, then sliding the sleeve over and securing the harness solves that. The engorged penis fills the inside of the sleeve, which removes dead space, improves the grip between you and the sleeve, and increases the friction you feel. The sleeve supports the whole length, so the hinge disappears. Two safety points if you do this: size the sleeve to your pumped girth rather than your soft measurements, and take the tension ring off within 30 minutes. We go deeper on this in our comparison of penis sleeves and penis pumps.

What does each one cost over time?

The sticker prices are not far apart. The Tenuto 2 sells in the low hundreds of dollars, and promotions are frequent. Our standard sleeves run $299 to $525, with a built-to-spec custom sleeve at $3,999.

The bigger difference shows up over several years. Cheap sleeves sold as novelties run $50 to $100 and are made from porous materials that tear, degrade, and get replaced, sometimes more than once a year. Buy three or four of those and you have spent what a real one costs, with none of the years of use. A well-made medical-grade* sleeve lasts years with basic care, because platinum-cured silicone does not break down the way soft plastics and cheaper silicone blends do. There is nothing to charge and nothing to fail electronically.

It is also worth comparing both devices against surgery. An implant runs into the tens of thousands of dollars, requires anesthesia, and carries permanent risks of mechanical failure and infection. Plenty of men with heart conditions or poorly controlled diabetes are not candidates for it at all. Both of the devices here are a fraction of that price and neither requires an operation.

Sleeves are also eligible for FSA, HRA, and HSA funds, which puts pre-tax dollars toward the purchase.

Common questions

Does the Tenuto 2 work if you cannot get an erection at all?

No. Constriction devices, including vibrating ones, have no way to create an erection from a soft penis. They restrict blood from leaving, which requires blood to already be there. With no natural response, the device is a tight band around soft tissue, and leaving it on under tension risks bruising and tissue injury.

Is the Tenuto 2 FDA approved?

No, and neither is an RX Sleeve. Both sit in FDA categories that are Class II and exempt from premarket review, so companies register with the FDA and list the device rather than obtaining clearance or approval. Marketing language like "FDA-registered" describes that listing, not an approval decision.

Can you ejaculate while wearing a penis sleeve?

Yes. Our sleeves are hollow with an opening at the tip, so ejaculation is not blocked and there is no need to remove the sleeve. The Tenuto 2 is contoured to keep pressure off the underside of the shaft for the same reason.

How long can you wear a vibrating ring versus a penis sleeve?

Any constriction device follows the 30 minute rule, because restricting blood flow longer than that risks tissue damage. A sleeve does not constrict blood flow, so there is no circulatory clock on it.

Which RX Sleeve model should I choose for severe ED?

Start with the Firm material, since it holds its shape around a soft penis without buckling. From there it is about matching the internal size and the outside dimensions you want. Send us your measurements and we will tell you which of our penis sleeve models fits, or whether a custom build makes more sense.

Do penis sleeves actually work for men whose medication failed?

They work differently from medication, which is why they still work when medication does not. Nothing about a sleeve depends on blood flow or nerve signaling. We have written more on that in do penis sleeves work.
