Of all the questions patients ask in a Himplant consultation, this is the most important to answer precisely: does size actually change? The honest, clinical answer is yes — but specifically in girth, not length, and with a magnitude that depends on the patient's own anatomy. Below is the explanation I give every patient before they make a decision: what the Himplant does, what it doesn't, and how we set realistic expectations together during consultation.
From Dr. Robbins' PracticePatients who go in with realistic expectations are nearly universally satisfied. Patients who expected something cinematic are sometimes disappointed because they didn't understand the device's purpose.
What the Himplant Is FDA-Cleared to Do
The Himplant is the only FDA-cleared subcutaneous silicone implant designed exclusively for long-lasting penile girth enhancement. "Subcutaneous" means it sits beneath the skin, in the same anatomical layer as the natural soft tissue. "Girth enhancement" means it adds circumference. "Long-lasting" means it is designed to remain in place long-term — backed by a manufacturer limited lifetime warranty, terms and conditions apply.
The implant is the only device in this category cleared by the U.S. FDA. The clearance language and the device's design intent are both very specific: girth enhancement, beneath the skin, long-lasting. Patients who understand exactly what is being claimed are the ones who arrive at follow-ups satisfied.
Flaccid Girth Changes Visibly
The most immediate visible change after a Himplant is in flaccid girth. The implant adds circumference to the soft, non-erect anatomy — which is the state men are in most of the time. Many of my patients report that the flaccid change is the one they notice most in daily life: clothing fits differently, appearance in the locker room or at the beach changes, and there's a confidence shift that operates in the background of every day, not just during intimacy.
Erect Girth Increases Proportionally
Erect girth also increases. The Himplant sits beneath the skin in a position where it adds circumference whether the penis is flaccid or erect, so the size change is present in both states. Because the soft silicone follows the natural contour of the patient's anatomy, the proportions stay natural — the result is a meaningfully larger version of the patient's own anatomy, not a fundamentally different shape.
What About Length?
The Himplant does not increase length. This is an important point of patient expectation. The implant is a girth-enhancement device — that is what it is designed for, and that is what it does well. Patients seeking length should have a different conversation, and length is not part of what we promise during a Himplant consultation.
Some patients notice a subtle change in flaccid presentation because the added girth alters how the penis sits when soft — but this is a perception effect, not a true length change. The honest framing is: Himplant means more circumference, not more length.
How Proportions Stay Natural
A common patient concern is whether the result will look or feel "obvious" or disproportionate. It doesn't, when the implant is sized correctly to the patient's anatomy. The soft silicone follows the contour of the natural tissue, and we choose implant sizing during consultation based on the patient's existing measurements and goals. The result is meaningfully larger but still recognizably the patient's own anatomy.
This is why the consultation matters. We measure, we discuss what's achievable, and we set expectations based on what the implant will actually do for this specific patient — not on internet claims or marketing imagery.
The Realistic Measurement Conversation
In every consultation, we measure baseline flaccid and erect girth, discuss what the Himplant typically adds, and talk through what that will look like for the patient's specific anatomy. We don't make promises in inches or centimeters — individual results vary based on starting anatomy, soft tissue characteristics, and implant sizing. What we do is set a realistic, anchored expectation based on examination, not aspirations.
Patients who come in with a number they've read online sometimes need a recalibration during consultation. Patients who come in asking what's achievable for them specifically — that's the right framing.
Long-Term: The Change Is Built to Last
The Himplant is designed to remain in place long-term. The result you have at six months post-procedure is essentially the result you have at year five, year ten, and beyond. The implant is backed by a manufacturer limited lifetime warranty (terms apply). In day-to-day reality, patients in their first several years post-procedure report continued satisfaction with the result.
Setting Expectations During Consultation
My approach during a Himplant consultation is to be specific. We measure first. We discuss what the implant will add given the patient's anatomy. We set an expectation that's grounded in the actual procedure, not in marketing imagery. Patients who come away with realistic expectations are the ones who report being satisfied at every follow-up afterward.

The Bottom Line
Yes, penis size changes after Himplant surgery — specifically, girth increases, in both flaccid and erect states, with proportions that stay natural to the patient's own anatomy. The implant does not increase length. The change is long-lasting and backed by a manufacturer limited lifetime warranty. Patients who set realistic expectations during consultation are nearly universally satisfied with the result.
