Penis Enlargement Surgery: Real Results, Satisfaction Rates and Risks

Ligament surgery adds about 1.3 cm on average, and only 35% of patients were satisfied in one study. Results, satisfaction rates and risks of each procedure.

Key takeaways

Penis enlargement surgery exists, and clinics advertise it aggressively, especially abroad and on social media. But it isn't a simple cosmetic fix. Gains tend to be small, satisfaction is low, and complications can be serious. In Mayo Clinic's words, no trusted medical organization endorses penis surgery done purely for looks.

Here's what the research shows about each type of procedure.

Length surgery: cutting the suspensory ligament

The penis is held to the pubic bone by the suspensory ligament. Cutting it lets some of the internal part of the penis slide outward. No new tissue is created. The penis just sits lower and further forward.

The results

The risks

A less stable penis during erection, difficulty with sex and penetration, and scar tissue that pulls the penis back in as it heals, which can leave it shorter than before. The London researchers' conclusion was blunt: these procedures may add length, "but usually not to a degree that satisfies the patient."

Girth procedures: fillers and implants

A 2025 review looked at the complications of girth procedures:

MethodKnown problems
Oil-based injections (paraffin, petroleum jelly and similar)Unapproved. Hard, disfiguring lumps (sclerosing lipogranuloma); may need tissue removal and skin grafts
Foreign-body injections or implantsPain, inflammation, nodules, ulcers, tissue death, deformity, gangrene, even death
Hyaluronic acid fillerBetter tolerated than other injectables; little long-term data
Silicone implant under the skinInfection, erosion, fluid build-up, tissue death; about 10% are removed
Tissue graftsCan improve girth and satisfaction; can reduce length

A 2020 systematic review of normal-sized men found that injections did add girth but came with a high complication rate. Its authors called injections and surgery "unethical outside of clinical trials."

When surgery does make sense

These operations were developed for real medical problems:

For these men, surgery can make a real difference to quality of life. For a man of normal size, the balance of risk and benefit looks very different, and most men who ask for surgery are normal. See the data in average penis size.

Five questions to ask any clinic

If a clinic promises "guaranteed results," "no risk" or "growth in 20 minutes," ask:

  1. Who is doing the procedure? Is it a urologist?
  2. Are there published studies showing long-term results for this method?
  3. What's the complication rate, and who treats you if something goes wrong?
  4. Can it be undone?
  5. Do they recommend a psychological assessment first?

A serious clinic will say yes to that last one. Men with penile dysmorphic disorder often have unrealistic expectations and should be offered psychological help first. Read more in penis size anxiety.

Evidence check. Small length gains from ligament release: moderate evidence, low satisfaction. Girth from fillers and implants: weak evidence, high risk. Oil-based injections: dangerous, avoid completely.

Frequently asked questions

How much length does penis enlargement surgery add?

Suspensory ligament division typically adds 1 to 3 cm of flaccid length in reviews. In a London study of 42 patients the average gain was 1.3 cm, and some men lost up to 1 cm.

Are men satisfied with penis enlargement surgery?

Often not. Only 35% of patients in the London study were satisfied, and 27% of men with penile dysmorphic disorder. Across studies, satisfaction ranges from about 30% to 65%.

Are penis girth fillers safe?

Hyaluronic acid fillers are better tolerated than other injectables but have little long-term data. Oil-based and foreign-body injections are dangerous and can cause hard lumps, tissue death and the need for skin grafts.

When is penis surgery medically appropriate?

For conditions such as micropenis, adult acquired buried penis, curvature and shortening from Peyronie's disease, tissue loss after injury or cancer treatment, and severe erectile dysfunction where a penile implant may be used.
