"Does penis enlargement actually work?" is one of the most-searched questions in men's health — and one of the most misleading corners of the internet. The honest, clinical answer is that most of what's marketed does nothing, and one category genuinely works. Below is how I sort it for patients: what the evidence supports, what it doesn't, and where a real, durable result is possible.
From Dr. Robbins' PracticeThe single biggest favor a man can do himself is to stop spending money on the things that don't work, and have one honest conversation about the thing that does.
Pills, Creams, and Supplements: No Evidence
This is the most heavily advertised category and the least supported. There is no pill, topical cream, or supplement with credible clinical evidence of permanently increasing penis size. Products in this space are unregulated as size-changers, and independent testing has repeatedly found supplements that are mislabeled or contaminated. If a product promises inches from a capsule, that is a marketing claim, not a medical one.
Pumps and Vacuum Devices: Temporary Only
Vacuum pumps do produce a visible short-term change — they draw blood into the tissue, causing temporary swelling. That effect is exactly that: temporary, resolving within hours. Pumps have a legitimate medical role in erectile rehabilitation, but as a permanent enlargement tool they don't deliver, and aggressive use can cause bruising or tissue injury.
Jelqing and Manual Exercises: Unproven and Risky
"Jelqing" and similar manual-stretching routines are popular online and unsupported by quality evidence. There is no controlled research showing they produce meaningful permanent gains, and I regularly see the downside in clinic: bruising, pain, scarring, and even injury to the erectile tissue from overly aggressive technique. The risk-to-benefit ratio here is poor.
Stretching and Traction Devices: Limited, and Length-Only
Traction (extender) devices are the one non-surgical approach with any peer-reviewed signal, and even then it is modest, targets flaccid length only, and requires wearing the device for hours a day over many months to achieve small gains. For most men seeking a meaningful change — especially in girth — the effort-to-result ratio is not compelling.
Surgery: Where a Durable Result Is Real
The category that actually delivers a lasting change in girth is surgical. The Himplant is the only FDA-cleared subcutaneous silicone implant designed exclusively for long-lasting penile girth enhancement. It is placed beneath the penile skin to add circumference in both the flaccid and erect states, in an outpatient procedure that typically takes 45 to 90 minutes. It adds girth in both states and also adds length in the flaccid (non-erect) state — though not erect length — and because the soft silicone follows the patient's own anatomy, the result stays proportionate and natural. The implant is backed by a manufacturer limited lifetime warranty (terms apply).
This is a real procedure with real recovery and real candidacy criteria — which is exactly why it works where capsules and gadgets don't. It should be evaluated in person, not ordered online.
How to Decide What's Worth Your Time
A simple filter: if a method is sold anonymously, promises dramatic results with no procedure, and has no physician behind it, treat the claim as advertising. If a method involves a consultation, a medical evaluation, and an honest discussion of what it can and can't do, it's worth understanding. Enlargement that works looks like medicine, not like a late-night ad.
The Bottom Line
Most penis-enlargement products do not work. Pumps are temporary, exercises are unproven and risky, and pills have no evidence at all. The one path to a durable increase in girth is surgical — and the FDA-cleared Himplant is the device specifically designed for it. At INTIMÉ Miami, Dr. David Robbins is one of a select number of urologists in the United States trained and authorized to perform the Himplant, having completed his training directly with Dr. James Elist, the device's inventor.
