The penile implant for size and shape is here — in fact, it’s been around for more than a decade. But before you go rushing off to remake your member in the “ideal” image, this is not necessarily a sudden windfall for your weiner.

Going under the knife to improve your sex life isn’t so simple, and neither is this (or any) penile surgery. Penile “implants” would seem to offer a lot of benefits, but cosmetic and aesthetic changes to your penis might not be as simple as you might think.

Penuma® isn’t the newest surgical option, but it does offer some benefits that other enhancement options do not. Let’s look at why it’s different, and whether it might benefit you in the bedroom.

Penuma Implants: What You Need to Know

Unlike some other products on the market, Penuma is not a penile prosthesis or inflatable erectile mechanic — it’s not actually designed to treat erectile dysfunction. It’s actually a cosmetic product; since 2004, Penuma has offered a medical grade silicone implant for your penis to increase both length and girth. 

We know what you’re probably wondering: how many sizes are offered? Well, the answer is one.

The FDA-cleared aesthetic implant increases flaccid length and girth by 1 to 2 inches on average, with varying results. 

The surgery is surprisingly simple: under general anesthesia, the implant is inserted along the shaft of your penis through an incision just above the base (the Penuma people really want it emphasized that there are no incisions on your actual penis, and we’re just as glad as they are).

Are Penuma Implants Worth It?

Well, here’s the thing: it depends on why you want a penile implant in the first place. If you’re looking for something to prop up your wilting willy, this is not the product for you. Penuma implants are strictly for visual and functional size augmentation — they don’t impact your performance. 

The only way your performance (specifically, your ability to maintain an erection) might be impacted is if you had a psychologically induced form of erectile dysfunction, like performance anxiety or low self esteem brought on by feelings of inadequacy. In that specific case, an extra inch or two might be a great confidence boost. But this is by no means a medically recommended solution for confidence issues, nor is it the kind of procedure you should consider undergoing lightly. 

There aren’t many studies available yet, but a single-surgeon study of 400 men on long-term follow up (two to six years, on average) found that more than 80 percent of subjects reported “high” or “very high” levels of satisfaction with the results. And photos on the Penuma website show some visually impressive gains in the flaccid space. 

The study had limitations. The surgeon in question was also the implant’s inventor. Most of the questions were related to self-confidence and self-esteem.

And there were complications. A little less than 5 percent of patients reported scar formation or infection, and 3 percent ended up reporting adverse events “necessitating device removal.” The good news is that none of the reporting patients reported changes in function, erections, or ejaculation. 

The bigger question is whether this implant is worth the money and, well, having surgery on or around your penis.

The Cost of Penuma Implants

Cost might seem like a straightforward question, but there are some complicating factors to estimating your particular price for a Penuma implant. One of the first complicating factors is the market — whether you’re having it done in Scranton or San Francisco. Depending where you live, you might be out more for services than in smaller markets with cheaper costs.

According to the Penuma website, the procedure “usually costs around $16,000 to $18,000 total.” But that’s not necessarily your entire average cost — particularly if you’re uncircumcised and need to be circumcised for the procedure. 

“Unless it’s done for medical purposes,” the Penuma website explains, “circumcision is considered an elective cosmetic enhancement procedure and, as a result, will not be covered by your health insurance.” 

They state that an adult circumcision, by their estimates, costs between $1,500 and $5,000 depending on where the procedure is done, and the type of anesthesia used.

What to Do Next

There are many surgeries available for cosmetic augmentation of the penis, ranging in technique from cutting ligaments, to the removal of fatty tissue around buried penises, to some stuff that gave us chills just from diagrams. 

There are certainly options available — the question is how much trauma you want to put yourself through downstairs for results that often aren't necessarily significant or necessary. 

What it comes down to is whether your confidence and your body image will be improved by a surgery, or by some therapy. 

Every guy is self-conscious about something, and because of the massive social importance we place on member size, it can feel like how big you are is attached to your value as a person. Guys get in fights over this stuff after all. 

But if the size of your penis is causing you emotional and mental distress, the smartest thing you can do is talk to a healthcare professional about your concerns. You’ll have to do this anyway before going under the knife, and in the meantime, you might be offered some other resources for your concerns.
