What is penis enlargement?

If you’d like a bigger penis, you’re in good company. It’s not a topic guys typically talk about, but interest in penis enlargement continues to rise, especially with newer treatments like fillers showing some good results.

That doesn’t take away the risks of unproven treatments, or the doubts of doctors on RealSelf, however. In fact, most think penis enhancement procedures—especially surgical ones—could put you at more risk than they’re worth.

Here’s what you need to know about common and emerging options.

Is penis enlargement right for me?

Penis enlargement procedures might be a good choice for you if:

  • You have an unusually small penis.
    If you have a penis that’s below average size (~5 inches when erect), you might consider the Penuma silicone implant, fat transfer, ligament release,  or injectable fillers.
  • Your penis is partly or fully hidden under fat and skin.
    In this case, consider liposuction and surgery to remove excess skin.
  • You have a perfectly fine penis but would simply like more length and girth.
    Doctors on RealSelf would urge you to consider the least invasive procedures first.

How much does penis enlargement cost?

On average, RealSelf members paid almost $6,000 for penis enlargement. Your cost will depend on the technique used, as well as your doctor’s practice location and level of experience.

What are my options for penis enlargement, and how do they work?

Some doctors and RealSelf members are seeing success with treatments like injectable fillers and PRP injections (platelet rich plasma, a serum made from your own blood). There’s also a silicone penile implant called Penuma that’s been cleared by the FDA.

More questionable procedures include fat transfer and penis enlargement surgery.

Injectable fillers

The same fillers people get in their face can be injected into the shaft of your penis in a bid for more girth, and potentially added length. New York plastic surgeon Dr. David Shafer, who first developed the treatment, prefers Juvederm Voluma XC or Juvederm Ultra PLus XC.

Having fillers injected into your penis sounds painful, but you shouldn’t feel a thing. You’ll get a numbing cream and an injected numbing agent to keep you comfortable during the treatment.

Expect the doctor to use about 10 syringes of filler on your first visit, maybe more if you have a longer penis. “Some patients, depending on their baseline size, choose to do 15 syringes,” says Dr. Shafer on the RealSelf blog.

This procedure “has the added advantage of being reversible,” Dr. Shafer says, which means it can be “melted away” if you don’t like it. “This is very rare,” he adds.

One RealSelf member raved about the procedure in this review, saying “I found this procedure to be an unqualified success. I would recommend it to anyone looking to increase their girth.”

PRP injections

The P-Shot (also called the Priapus Shot) or STIM Shot is a series of injections using platelet-rich plasma (PRP). Distilled from your own blood, PRP has concentrated natural growth factors that some doctors say can enhance your erection, as well as sensation.

“The idea is to restore or improve nerve ending function and microvascular circulation, which can lead to improved blood flow” says Beverly Hills plastic surgeon Dr. Tim Neavin in a RealSelf Q&A. “More blood flow leads to larger erections and overall improvement in the sexual experience for men.”

Besides enhancing penis size and erections, PRP injections are also “a natural, nonsurgical approach to the treatment of erectile dysfunction or Peyronie’s disease, an ailment causing curved, painful erections,” says Elk Grove, California, physician Dr. Mahmoud Khattab.

Like injectable fillers, these treatments involve injections into your penis. First, the doctor will draw blood, usually from your arm, and spin it in a centrifuge to isolate the PRP. Then you’ll get a local and topical anesthetic to keep you comfortable.

“Procedures using PRP are quick,” says Dr. Neavin in a RealSelf Q&A, “and use a very small needle.” After the injections, Dr. Neavin has patients apply a penis pump for about 10 minutes to draw blood into the penis and fully disperse the PRP and allow the PRP to work at maximum capacity.

Penuma silicone implant

Penuma is a permanent implant, the only such treatment that’s been cleared (though not yet fully approved) by the FDA for penile enhancement. It’s made of soft, medical-grade silicone that’s softer than breast implants.

Slipped through a two-inch incision just above the base of the shaft (with no incisions or scars on the penis), the Penuma implant extends the length and girth of your penis by 1.5 to 2.5 inches.

It’s an outpatient surgery, about 45–60 minutes long, done under general anesthesia.

At the moment, Dr. James Elist, a urologist in Beverly Hills, is the only surgeon offering this procedure. He’s done over 2,500 of them so far, and a clinical study he commissioned shows a 95% success rate. The surgery costs around $15,000, and although he doesn’t accept insurance, he does offer financing.

Penuma should also be offered by more plastic surgeons across the country soon, once it’s fully FDA approved.

Fat transfer

Fat injections are a fairly common way for doctors to add bulk to other areas of the body, like the facebreasts, and butt. They’ve tried it in the penis as well, but with imperfect results. Memphis plastic surgeon Dr. Peter Aldea explains in a RealSelf Q&A that “the penile skin is very thin, and the space between it and the shaft does not have a rich blood supply. As a result, fat grafting in this area is unreliable at best and often results in small clumps of fat.”

One RealSelf member experienced exactly that, saying that “The fat ended up in a mass and looked like a big bump,” not the result he’d hoped for.

That might stem from the doctor’s technique, says Dr. Neavin in a RealSelf Q&A. “Fat historically had its issues with fat nodule development,” he explains. “However, with small cannulas, refined fat harvesting, injection, and post-operative care, this appears to be less of an issue.” Some doctors, including Dr. Neavin, use a technique called the STIF Shot, an injection of fat and PRP that increases both size and sensation.

If you’re interested in a fat transfer, ask plenty of questions about your doctor’s technique, ask to see before-and-after results, and seek out patient reviews to make sure your surgeon really knows what he’s doing.

Penis enlargement surgery

“There are some real reasons why penis enlargement is not a mainstream surgery,” says Dr. Peter Aldea, a Memphis plastic surgeon, in a RealSelf Q&A. “It is fraught with complications and distraught men.”

One procedure with very mixed (and even problematic) results is ligament release surgery, which cuts the ligament in your penis that’s responsible for making it erect. This makes it hang down and look bigger, but it also prevents it from standing up during an erection, which can make it more difficult to have sex.

If you have a hidden penis, first consider liposuction to remove extra fat, along with surgery to remove excess skin above your penis and make more of your shaft visible.

When will I see results of penis enlargement?

With injectable fillers, you should see full results in about a month. Then, says Dr. Shafer, “We like to see patients back about four to six weeks after their first treatment. At that appointment, some patients choose to have additional injections for added effect.”

For the P-Shot, Dr. Khattab says that “typically, the results are immediate, but optimal three­ to four weeks after the procedure.”

With the Penuma silicone implant, you’ll see immediate results when you’re flaccid, but you’ll need to wait at least four weeks before seeing more length in your erection. You’ll also need to wait that long to fully heal before having sex or masturbating, or you’ll risk complications.

How long will my penis enlargement results last?

It’s not entirely clear yet how long injectable fillers persevere in the penis, but Juvederm Volumatypically lasts nine months to a year when injected in the face.

For the P-Shot, results typically last up to two to three months. But repeated treatments could expand the vessels and tissues in your penis, giving more lasting results over time.

The Penuma silicone implant is permanent, and its effects will continue until you remove it.

What are the risks or potential side effects of penis enlargement?

Injections of fillers or PRP could cause some soreness or minor bruising, which shouldn’t last beyond a few days. Avoid sex for at least 48 hours after your treatment, to let the injection sites heal and minimize your risk of infection.

The Penuma silicone implant has few risks if you follow the post-op instructions, especially avoiding sex and masturbation for a month while you heal.

If it’s not done right, fat transfer has several risks. San Francisco plastic surgeon Dr. Mats Hagstromsays in a RealSelf Q&A that “it has left many patients massively disfigured. I have yet to see or hear of someone who has been pleased with the outcome. Be careful and listen to expert advice from board-certified plastic surgeons.”

Dr. Aldea adds that “Injecting fat into the space between the penis skin and the tough tight layer below is associated with near complete loss of the graft as well as nodules, scarring and potential ulcers. Injecting fat deeper risks blockage of the vascular spaces required for proper erection.” If you decide to go this route, find a doctor with a well-documented track record of success.
