Metoidioplasty is a surgical procedure performed as part of female-to-male (FTM) gender confirmation surgery. It involves using the tissue of the hormonally enlarged clitoris to create a neophallus, or new penis.

The size of the neophallus in metoidioplasty is limited by the length of the clitoris, which is typically enlarged due to testosterone hormone therapy. The average length of the neophallus after metoidioplasty varies, but it’s generally in the range of 4 to 10 centimeters (approximately 1.5 to 4 inches) when erect. It’s important to note that individual results can vary widely.

One of the advantages of metoidioplasty is that it usually preserves sexual sensation and the ability for spontaneous erections, as it utilizes the patient’s own clitoral tissue. However, the resulting phallus may not be large enough for penetrative intercourse, which is a consideration for individuals choosing between metoidioplasty and other procedures, such as phalloplasty.

Choosing a surgical procedure for gender confirmation is a highly personal decision that should be made in consultation with knowledgeable and experienced healthcare providers. The best procedure for an individual depends on their goals, expectations, and overall health.
