Metoidioplasty and phalloplasty are two surgical options for creating a penis in female-to-male (FtM) gender confirmation surgery.

Here’s a basic comparison:


  • Procedure: Metoidioplasty takes advantage of the fact that testosterone therapy enlarges the clitoris. During surgery, the enlarged clitoris is released from its ligaments and moved forward to a more typical position for a penis. Additional procedures can be performed to create a scrotum and lengthen the urethra to allow for urination through the neopenis.
  • Result: The resulting penis is smaller (usually around 2-3 inches when erect) but can become erect without the need for a penile implant. Sexual sensation is typically preserved since the clitoral nerve is not disturbed.
  • Recovery: Recovery time is generally shorter and less complex than for phalloplasty, and the procedure has fewer complications.
  • Cost: The cost is generally lower than for phalloplasty.


  • Procedure: Phalloplasty involves constructing a penis using skin from another part of the body, such as the forearm, thigh, or back. This results in a larger penis than with metoidioplasty. A urethral extension can be created, and a penile implant can be inserted in a later surgery to allow for erections.
  • Result: The resulting penis is larger and more like a cisgender male’s penis in terms of size and appearance, but the ability to achieve an erection requires a penile implant. The use of skin grafts can lead to scarring on the donor site.
  • Recovery: Recovery from phalloplasty is generally longer and more complex than from metoidioplasty, with a higher risk of complications such as fistulas or strictures in the newly created urethra.
  • Cost: The cost is generally higher due to the complexity of the procedure and the potential need for multiple surgeries.

Choosing between metoidioplasty and phalloplasty is a personal decision that depends on the individual’s goals, overall health, financial resources, and other factors. Both procedures have pros and cons, and it’s important to discuss these in detail with a knowledgeable healthcare provider.
