The Penuma penis enlargement procedure has an out-of-pocket cost of about $13,000 with an up-front $2,500 deposit.

Your health insurance may not cover Penuma unless you have a condition that qualifies for coverage, such as:

At this time, Penuma is the only penis enlargement surgery cleared for commercial use under the Food and Drug Administration’s (FDA) 510(k) regulation. It’s not fully approved by the FDA, but it can legally be marketed as a safe and effective procedure.

James Elist, MD, FACS, FICS, of Beverly Hills, California, founded the procedure. He’s currently the only certified practitioner.

Read on to learn more about how the Penuma procedure works, what your risks are, and whether it’s proven to successfully enlarge a penis.

The Penuma is a crescent-shaped piece of medical-grade silicone inserted under your penis skin to make your penis longer and wider. It’s provided in three sizes: large, extra-large, and extra-extra-large.

The tissues that give your penis its shape are composed largely of three main structures:

  • Corpus cavernosa. This refers to two cylindrical pieces of tissue that run parallel to each other along the top of your penis.
  • Corpus spongiosum. This is one cylindrical piece of tissue that runs along the bottom of your penis and surrounds your urethra, where urine comes out.

Your individual Penuma device will be designed to fit your specific penis shape. It’s then inserted into your shaft over the corpus cavernosa, like a sheath. This is done through an incision in your groin area just above the base of your penis. The device stretches the penis skin and tissues to make your penis look and feel larger.

People who have had the Penuma procedure done report increases in length and girth, or measurement around, their penis of about 1.5 to 2.5 inches, both while flaccid and erect.

The average male penis is about 3.6 inches long (3.7 inches in girth) when flaccid and 5.2 inches long (4.6 inches in girth) when erect. The Penuma could enlarge the average penis up to a length of 6.1 inches when flaccid and 7.7 inches when erect.

Things to consider

Here are some key facts about the Penuma surgery:

  • If you aren’t already circumcised, you’ll need to do this before the procedure.
  • You can go home the same day as the procedure.
  • You’ll need to arrange a ride to and from the procedure.
  • The procedure generally takes 45 minutes to an hour to complete.
  • Your surgeon will use general anesthesia to keep you asleep during the procedure.
  • You’ll return for a follow-up visit two to three days later.
  • Your penis will be swollen for a few weeks after the surgery.
  • You’ll need to abstain from masturbation and sexual activity for about six weeks.

As with any surgery, risks are associated with the use of anesthesia.

Common side effects of anesthesia include:

  • nausea
  • vomiting
  • exhaustion
  • hoarse voice
  • confusion

Anesthesia can also increase your risk of:

The Penuma website reports that you may experience pain with erection, as well as some loss of penis sensation, during the first few weeks. These are usually temporary.

If these side effects last for more than a few days, see your doctor. In some cases, removing and reinserting the Penuma can alleviate these side effects.

According to an evaluation of men who underwent this type of surgery, possible complications include:

You may not be satisfied with the shape of your penis after the surgery. It can make your penis look significantly bulkier or not shaped to your liking. Make sure you discuss realistic expectations for your penis appearance with your surgeon before you have the procedure done.

According to the Penuma website, the success rate of this procedure is high. Most side effects or complications are purportedly due to people not following surgical aftercare instructions.

Keep in mind that the Penuma hasn’t been scientifically or systematically tested. All information on the Penuma website is provided by the only surgeon who’s qualified to perform the procedure.

The surgical evaluation did find that 83.5 percent of 400 men who took a follow-up questionnaire about the procedure rated their satisfaction with their results at least 2 on a scale from 1 (low) to 4 (very high).

The Penuma procedure is expensive. It can also result in unwanted, sometimes permanent side effects.

If you’re concerned about the length and girth of your penis, talk with your doctor. They may be able to recommend nonsurgical options that can help you achieve your desired result.

Your doctor may not recommend and most likely won’t perform enlargement surgery or similar procedures unless you have ED or another penile condition. The Penuma procedure may currently be your only surgical option for aesthetic enlargement.
