What is Anterolateral Thigh Flap Phalloplasty?
Anterolateral Thigh Flap Phalloplasty creates a penis for a transgender man using skin and fat from the outer thigh. Because the thigh has plentiful tissue, this flap can build a substantial shaft. A transgender man is a man, so the goal here is a masculine, functional result that suits his own priorities and lifestyle.
Why do some men choose the thigh over the forearm?
The strongest reason is the scar, since the thigh donor site is easily covered by shorts or trousers. Many men who dislike a visible arm scar prefer this option for that privacy. Furthermore, the thigh often leaves the forearm untouched, which can matter for work, culture or personal comfort.
How is the thigh flap surgery carried out?
The surgeon marks and raises the flap from the outer thigh, keeping its blood supply intact. Depending on your anatomy, the flap may stay on nearby vessels or be moved with microsurgery. After shaping the shaft, the team closes the thigh, and later stages refine the urethra, glans and other details.
Is the thigh flap bulkier than the forearm flap?
Yes, thigh tissue is usually thicker, so the resulting shaft tends to be bulkier. For some men this feels like an advantage, while for others thinning is needed at a later stage. Because thickness varies widely, the surgeon assesses your thigh carefully and explains what girth is realistic for you.
Why is the urethra often built in two stages?
The extra bulk of thigh skin can make it harder to form a slim inner urethra within the first flap. For this reason, standing urination is frequently planned as a separate, later stage. Our urethral lengthening page explains this work and its common complications honestly.
How does it compare with the forearm flap?
Each flap has clear trade offs, and the table below summarises them. In short, the thigh hides its scar and adds bulk, while the forearm often gives finer sensation and a one stage urethra. You can compare in detail on our Radial Forearm Free Flap Phalloplasty page.
| Feature | Thigh flap | Forearm flap |
|---|---|---|
| Donor scar | Hidden on thigh | Visible on forearm |
| Shaft bulk | Bulkier | Slimmer |
| Sensation | Usually less | Often very good |
| Urethra timing | Often a second stage | Frequently one stage |
What sensation can I expect?
Thigh skin generally carries fewer fine nerves than forearm skin, so sensation tends to be more limited. Even so, nerves can be joined where anatomy allows, and feeling may build slowly over months. Because outcomes differ from natal anatomy, the team is honest that erogenous sensation cannot be guaranteed.
Is this a staged operation?
Yes, like all phalloplasty, this is staged over more than one procedure. The first stage forms the shaft, and later visits may add the urethra, a glans, a scrotum and implants. Since healing between stages takes time, the complete pathway usually runs across a year or more.
What are the honest risks?
Real risks include partial or total flap loss, wound breakdown and infection. When the urethra is lengthened, fistula and stricture are common and often need repair. The thigh scar is permanent, sensation may be reduced, and any later implant carries its own hazards. Revision is common and does not signal failure.
How do hormones and fertility fit in?
Testosterone alters tissue gradually, so surgical timing is coordinated with your prescribing doctor and the surgical team. You should never stop or change hormones on your own around an operation. Since treatment can affect fertility, preservation is raised before you begin where biological children may matter to you.
How do I prepare for thigh flap surgery?
Preparation begins weeks in advance, and the team walks you through every step. Since healthy circulation protects the flap, you are strongly advised to give up smoking, because tobacco slows wound healing and endangers the thigh tissue. Routine blood tests, a check of your general health and a review of your medicines are arranged first. Furthermore, you organise rest at home and time off, as walking may feel stiff while the thigh donor area recovers in the early period.
What happens during the first weeks of healing?
Immediately after the shaft is built, you are monitored in hospital so the team can confirm the flap is healthy. Because movement can strain the thigh wound, you are guided on how to sit, stand and walk gently at first. Over the following weeks, swelling eases and the donor site closes, though full comfort takes longer. Throughout this time, you attend planned reviews, and the surgeon decides when the next stage, such as the urethra, can safely begin.
Which standards guide this care?
Care follows the current WPATH Standards of Care version 8, covering individualised assessment, informed consent and postoperative planning. Because rules differ by surgeon, hospital and country, the team clarifies what applies to your situation. Fuller counselling and eligibility sit with our dedicated transgender health service.
Where is this done, and what will it cost?
This bulky, staged reconstruction is often performed in a specialist centre or by a visiting super specialist with the right microsurgery skills. Costs are quoted in rupees, and you receive a clear written estimate after examination. As each journey is unique, the team avoids fixed prices until you have been assessed.
