Phalloplasty and metoidioplasty are the two main forms of FTM bottom surgery, and the right choice depends on what matters most to you. Phalloplasty builds a larger, adult-sized phallus from a skin flap, which can allow penetrative sex with an implant, but it needs more stages, leaves a donor-site scar, and costs more. Metoidioplasty uses the genital tissue that has grown with testosterone to create a smaller phallus, with fewer stages, no flap, strong preserved sensation and lower cost, but limited size and usually no penetrative capability. Both can be done with urethral lengthening so you can urinate standing.
The two options at a glance
Both procedures are forms of masculinising bottom surgery, but they take very different routes. The table gives the headline comparison; the sections below go deeper on each point.
| Phalloplasty | Metoidioplasty | |
|---|---|---|
| How it is made | From a skin flap (forearm or thigh) | From the testosterone-enlarged genital tissue |
| Size | Adult-sized phallus | Smaller phallus |
| Penetrative sex | Possible with an erectile implant | Generally not possible |
| Standing urination | Yes, with urethral lengthening | Yes, with urethral lengthening |
| Sensation | Grows in over months; strong with forearm flap | Strong, preserved from the start |
| Stages | Several, over about 1 to 2 years | Fewer, shorter overall |
| Donor scar | Yes (arm or thigh) | No flap, so no donor scar |
| Cost | Higher | Lower |
Size and appearance
The most obvious difference is size. Phalloplasty creates an adult-sized phallus, which is the main reason people choose it: it looks proportionate in and out of clothing and allows for penetrative sex with an implant. Metoidioplasty creates a smaller phallus from the clitoral tissue that testosterone has already enlarged, so the size is more limited, though it is a natural-looking phallus with its own advantages.
Which matters more is personal. Some people strongly want the size and capabilities phalloplasty offers and accept the extra surgery to get them. Others feel that a smaller phallus made from their own tissue, with fewer operations and a quicker recovery, fits them better. Neither preference is more valid; they are simply different priorities, and being honest with yourself about which you hold is the start of the decision.
Sensation
Both procedures can give good sensation, but they get there differently. Metoidioplasty uses the existing, richly innervated genital tissue directly, so erogenous sensation is preserved from the outset and tends to be excellent, one of its clearest strengths. Phalloplasty aims for sensation by connecting nerves during surgery, and feeling then grows into the phallus over months as the nerves regenerate, with strong results reported particularly with the forearm flap.
So both can be sensate, but metoidioplasty keeps sensation intact immediately, while phalloplasty builds it over time. For people for whom preserved erogenous sensation is the top priority, this is often a point in metoidioplasty’s favour. For those prioritising size and penetrative function, phalloplasty’s sensation, developed over the first year, is usually very satisfactory.
Standing to urinate
Good news here: both procedures can be done with urethral lengthening so that you can urinate standing. This is not a point of difference in what is achievable, only in the details. In both, lengthening the urethra is the part with the highest rate of complications, chiefly narrowing or small leaks that can need a minor further procedure.
In both procedures you can also choose not to have urethral lengthening and keep your original urethra, which avoids that specific set of risks. So standing urination is available with either surgery if you want it, and is optional in both. Your surgeon can explain how the lengthening is done in each and what the complication rates look like in their hands.
Penetrative sex
This is a genuine point of difference. Phalloplasty, with an erectile implant added in a later stage, can allow penetrative sex, because the implant provides the rigidity the phallus does not have on its own. For many people who want that capability, it is the deciding factor in choosing phalloplasty.
Metoidioplasty generally does not allow penetrative sex, because the phallus, while sensate and capable of becoming erect to a degree on its own, is too small for penetration. It can still allow a satisfying sex life in other ways, and its preserved sensation is a real strength here. So if penetrative sex is a priority, phalloplasty is usually the route; if it is not, metoidioplasty’s advantages come to the fore.
Stages, recovery and scars
The two procedures differ substantially in how much surgery and recovery they involve. Phalloplasty is staged over several operations spanning roughly one to two years, with a significant first stage, and it leaves a donor-site scar on the arm or thigh that has its own healing. Metoidioplasty generally involves fewer and shorter stages, no flap and therefore no donor scar, and a quicker overall recovery.
For some people, metoidioplasty’s lighter surgical footprint, fewer operations, no donor scar, faster return to life, is a major draw in itself, quite apart from size or function. For others, the additional stages of phalloplasty are simply the price of the result they want. It is worth thinking honestly about your appetite for surgery and recovery time, not just the end result, because you live through the process as well as the outcome. Our guide to how phalloplasty works details its stages.
Cost
Cost follows complexity. Metoidioplasty is usually less expensive than phalloplasty, because it involves fewer and shorter stages and no flap reconstruction. Phalloplasty, as staged microsurgery with a donor flap and optional implants, sits at the higher end of gender-affirming surgery costs.
For people weighing cost heavily, this can be a real factor, but it is worth deciding on the surgery that fits your goals first and comparing costs second, rather than choosing the cheaper option and finding it does not give you what you needed. Our phalloplasty cost guide and pricing page set out indicative figures for coordinated packages in Thailand, which are a fraction of US and UK prices for either procedure.
How to choose
There is no better procedure in the abstract; there is only the one that fits your priorities. A useful way to decide is to rank what matters most to you: size, penetrative capability, preserved erogenous sensation, the fewest operations and quickest recovery, avoiding a donor scar, and cost. Phalloplasty tends to win on size and penetrative function; metoidioplasty tends to win on sensation, fewer stages, no donor scar and lower cost; both offer standing urination.
Once you know your own ranking, the choice usually becomes clearer, and a consultation with an experienced surgeon is where it is confirmed against your specific anatomy. A good surgeon will not push you towards the bigger operation, but will help you match the procedure to what you actually want. Take your time; this is a decision worth getting right for you rather than rushing.
What both procedures share
For all their differences, phalloplasty and metoidioplasty have a lot in common, and it helps to hold this in mind so the decision does not feel more all-or-nothing than it is. Both are established forms of masculinising bottom surgery performed by specialised surgeons; both can include a hysterectomy and removal of the vaginal canal as part of the plan if you want them; both can create a scrotum from local tissue with the option of testicular implants; and both, as we have seen, can offer standing urination through urethral lengthening. In other words, many of the components are shared, and the core choice is really about the phallus itself, how it is made, its size, and what it can do.
It is also worth knowing that neither is a decision you have to make in isolation or in a rush. These are significant, elective procedures, and taking the time to read, to talk to a surgeon, and to sit with what matters most to you is exactly the right approach. There is no clock running, and the goal is the choice that is right for you rather than the one that sounds most complete on paper.
Eligibility and getting ready
For either procedure, surgeons generally work within the framework of the WPATH Standards of Care (SOC-8) together with each hospital’s own assessment. In practice that usually means being an adult able to give informed consent, having realistic expectations of what the surgery can and cannot do, and, for bottom surgery specifically, often a period on testosterone and sometimes prior chest surgery, though requirements vary by surgeon and hospital.
Getting ready also has practical dimensions: some people need hair removal on the flap or urethral area beforehand, and both procedures ask for a genuine commitment to aftercare and, for phalloplasty, to a staged journey over time. None of this is meant to gatekeep; it is about making sure the surgery is safe and that you go in informed. We can talk you through what a specific surgeon expects, with interpreting if you need it, before you commit to anything.
