The short answer
Very few things make the penis bigger, and none of them adds a large amount of erect length. Hyaluronic acid filler adds girth for a limited time. Fat transfer adds girth but part of the fat is reabsorbed, often unevenly. Cutting the suspensory ligament makes the flaccid penis hang lower but does little for erect length. Silicone sleeve implants add girth but carry a meaningful complication rate. Traction devices may give a small change over months. Pills, creams, exercises and pumps have no reliable evidence of lasting enlargement. Most men who ask about enlargement are within the normal size range, which is why a proper assessment comes before any treatment.
Key takeaways
- No method reliably adds a large amount of erect length. Most medical treatments add girth, not length.
- Hyaluronic acid filler is temporary and can be dissolved; fat transfer is unpredictable; surgery is permanent and carries surgical risks.
- Pills, creams, pumps and stretching exercises have no good evidence of lasting enlargement.
- Most men who worry about size measure within the normal range. Assessment and honest counselling come before any procedure.
Why start with what is normal?
Almost every man who asks me about enlargement begins by assuming he is small. Most are not. When health professionals measured more than 15,000 men for a 2015 review in the BJU International, the average erect length was about 13.1 cm and the average erect girth about 11.7 cm. The majority of men who come to a clinic asking for enlargement measure within the normal range. That is not a reason to dismiss the concern, but it is a reason to measure properly and talk honestly before anyone picks up a syringe or a scalpel. Our article on what penis size is actually normal covers the figures in more detail.
European urology guidelines take the same view: men with a normal-sized penis who want enlargement should be assessed and counselled first, because the worry often responds better to information and support than to a procedure.
What can change length?
Very little, and this is the part the advertisements leave out.
- Suspensory ligament release. The ligament that anchors the penis to the pubic bone is cut, so the flaccid penis hangs lower and looks longer. Erect length barely changes, because the part of the penis that was inside the body still is. Some of the visible gain can be lost as scar tissue forms, and the erect penis may feel less stable at the base. Surgical reviews report modest average gains and a real complication rate.
- Removing a pubic fat pad. In men with a lot of fat above the pubic bone, liposuction or weight loss reveals shaft that was already there. This is the one case where the visible length genuinely improves, without touching the penis itself.
- Traction devices. A small number of studies suggest that an extender worn for several hours a day over months may add a small amount of length in some men. The evidence is limited and the commitment is considerable.
Injections, pills, creams and pumps do not add erect length. If your penis has become shorter, or has developed a bend, the cause may be Peyronie's disease or longstanding erectile dysfunction, and that needs a different assessment entirely.
What can change girth?
Girth is where medical treatments actually do something, so this is where most of the real choices lie.
- Hyaluronic acid filler. A medical gel is injected under the skin of the shaft under local anaesthetic. The change is visible straight away, the body breaks the gel down over time, and it can be dissolved early if needed. It is the least invasive option and the one we offer, described on our penile filler page. Its use in the penis is off-label in most countries, and results vary between men.
- Fat transfer. Fat is taken from the abdomen or thigh and injected into the shaft. The fat that survives is permanent, but a substantial part is reabsorbed, sometimes unevenly, which can leave lumps or an irregular contour. We do not offer it; our article on fat transfer explains why.
- Silicone sleeve implants. A soft silicone sleeve is placed under the skin of the shaft in an operation. The change is designed to be lasting, but published series report infections, seromas, erosion and removals in a meaningful proportion of men.
- Grafts. Sheets of tissue placed around the erectile bodies. This is major surgery, mostly described in small series, with risks to sensation and erection.
What does not work?
Pills and supplements have no evidence of changing penis size, and some products sold online have been found to contain undeclared prescription drugs. Creams and gels cannot reach the tissue that would need to grow. Vacuum pumps produce a temporary swelling that goes down within minutes; they are useful for erectile dysfunction, not enlargement. Stretching exercises such as "jelqing" have no evidence of benefit and can bruise or scar the shaft.
The most dangerous category is injection of substances that were never meant for the body: liquid silicone, paraffin, petroleum jelly or oils. These cause chronic inflammation, hard lumps, deformity and sometimes tissue loss, and the damage is often permanent. Any treatment where the product and the amount are not named should be refused.
How do the options compare?
| Method | Changes | How long it lasts | Main drawbacks |
|---|---|---|---|
| Hyaluronic acid filler | Girth | Temporary; gradually broken down | Off-label; swelling, lumps, migration; repeat treatment to maintain |
| Fat transfer | Girth | Unpredictable; part is reabsorbed | Uneven result, lumps, cysts; needs liposuction |
| Suspensory ligament release | Flaccid appearance | Permanent surgery | Little erect gain; scar tissue; less stable erection base |
| Silicone sleeve implant | Girth | Designed to stay | Infection, seroma, erosion, removal in some men |
| Traction device | Length, small | Depends on continued use | Hours a day for months; limited evidence |
| Pills, creams, pumps, exercises | Nothing lasting | n/a | No evidence; some products unsafe |

What about penile implants?
A penile implant is a treatment for erectile dysfunction, not a size treatment. It restores a firm, reliable erection, but it does not add natural length, and some men notice the erect penis feels slightly shorter afterwards. For men who need an implant and also want more girth, the two can be combined in one operation; this is what our Magic Touch package describes. Nobody should have an implant purely to look bigger.
What should you ask before any treatment?
- What exactly will be injected or implanted, and how much?
- Is the product approved for this use, or is it off-label?
- What is the realistic range of change, and how long does it last?
- What are the complications in your own patients, and how are they treated?
- What happens if I am unhappy with the result?
A doctor who promises a fixed number of centimetres, or a result without complications, is not describing medicine. The honest answer is always a range, and the honest consultation always includes the option of doing nothing.
When to see a doctor
See a urologist if worry about size is affecting your confidence or your sex life, if you have noticed a change in length or a new curve, or if you have already had an injection of an unknown substance. The first appointment is a measurement and a conversation, nothing more. For many men it is also the last one they need.
Questions men also ask
Can the penis be made longer?
Only modestly. Cutting the suspensory ligament lets the flaccid penis hang lower, but erect length changes little and some of the gain can be lost to scar tissue. No injection or device adds meaningful erect length.
What is the safest way to add girth?
Hyaluronic acid filler has the most favourable safety profile of the girth options because it is placed under local anaesthetic, involves no surgery and can be dissolved with hyaluronidase if there is a problem. It is still a medical procedure with real risks, and its use in the penis is off-label.
Do penis enlargement pills or creams work?
No. There is no reliable evidence that any supplement, pill or cream increases penis size. Some products sold online contain undeclared prescription drugs.
