Penis Enlargement (Phalloplasty)

A penis can be enlarged in two ways: by increasing the length, and increasing the girth (circumference). Increasing the girth of the penis is a more complex procedure. Both procedures can be performed together or in isolation.

This article discusses both procedures but does not discuss phalloplasty for penis construction, as is needed in sexual reassignment surgery.

Penile lengthening surgery will increase only the length of a flaccid penis, not an erect one.

Average penis length is something that is increasingly discussed, often inaccurately. Various scientific studies have shown that the average erect penis length is around 13cm (5 inches). A study done by LifeStyles condoms found that almost all men fall somewhere between an erect length of 10cm (4in) and 18cm (7in), with around 80% of penises shorter than 15.9cm (6.25in).

Flaccid length varies even more and bears almost no correlation to erect length. An apparently small flaccid penis may grow considerably in length and girth when erect, whereas a large flaccid penis, when erect, may not change much in size at all. Various studies have found the average flaccid length to be around 9cm (3.5in).

Between one-third and one-half of the penis is housed inside the body. It is relatively easy to increase the flaccid penis length by cutting the suspensory ligament, which holds the penis close to the pubic bone and supports it during an erection. Through the use of penile weights, this ligament eventually heals in an extended state, with more of the penis hanging outside the body than before. Another method to increase penis length is through liposuction (fat removal) to the pubic area, which simply exposes more of the penis. Unlike the cutting of the suspensory ligament, liposuction to the pubic area can give the impression of a longer erect penis without increasing the structure of the penis through surgery.

Increasing the girth or circumference of the penis is slightly trickier. There are two main techniques: injecting fat into the penis and inserting grafts of tissue and fat, usually taken from the groin or buttock area. This second procedure is called a dermal fat-graft augmentation.

Fat injections were the first technique developed by surgeons and can increase girth up to 50%. The results of this procedure are unpredictable, however, because fat is often reabsorbed into the body. The amount of reabsorbed fat ranges from 25% to 90%. To allow for this reabsorption, surgeons typically inject more fat than is required.

Dermal fat-graft augmentation was developed as a solution to the problems associated with the fat transfer technique. In dermal fat-graft augmentation two strips of tissue are removed, typically from the buttocks, in a place where a scar will not be obvious, e.g. the crease where the leg joins the buttock. These strips are usually about 5cm wide and 12cm long. The tissue is then inserted under the skin of the penis. Fat reabsorption, which is common with fat injections, is mostly avoided using this technique because the tissue has a layer of skin on one side.

    It says the suspensory ligament supports during. Is the support lost once it’s cut? I can’t picture the end result, and I don’t fancy googling it. Lol

    Hi there can any one tell me approx cost for demal fat graft and lengthening and wether or not it’s worth it I have 7.5 cut and hard would like another 2 or 3 inches and would like to widen it like a red bull can is this possible

    • Costhetics says:

      Hello thank you for your enquiry. It is difficult to obtain extra length with penis enlargement, generally it is minimal amount of extra length but considerably more width.

      Costs for Phalloplasty including surgeons fees, hospital stay etc. are usually around 15K. I recommend you visit a doctor in your state as usually a 3-4 day hospital stay is required.

  • Francisco says:

    I was interested in an operation to lengthen the penis size and would like to inform me of some aspects such as how many centimeters can be increased, if it is dangerous …
    Thanks in advance. A greeting.

  • Costhetics says:

    Hi Ben,
    Given you had the surgery such a short time ago, I would contact your surgeon with these questions. It’s really important to follow your surgeons instructions to the word as they will have thorough knowledge of how much time you need to recover based on the extent of your surgery.
    Generally, 6 weeks is given as the recovery time to ensure all incisions heal properly. You may well be able to use your penis sooner but this is a question for your surgeon.
    Regarding the lumps you’ve found, I would also contact your surgeon about this immediately and request a post-operative visit to ensure that your body is healing correctly.
    Best wishes for a speedy recovery Ben!

      I wanted to follow up on comment about fat injections clumping up.

      Ben, what did you doctor say? I spoke with mine and he mentioned I should wear the extender and through time it will fade (clumping will go down)?

      I had surgery about 3 weeks ago and half clumping but feel like nothing will help. I might just be over thinking this or impatient but am worried it is PERMANENT…despite what the doctors has said.

      I just wanted to get your thoughts Ben and Costhetics…


  • Ben says:

    Hi i have recently had a width and length surgery done on my penis, the surgery was done 2 and a half weeks ago now i had a couple questions.

    1. if i feel comfortable enough to masterbate can i? and why are we given a 6 week guide not to?

    2. i had liposuction and then the fat injected into my penis and it has caused lumps, even though it’s only been just over 2 weeks will these lumps eventually absorb over time?

    Thank you.
