Metoidioplasty, sometimes referred to as a meto or meta, is an alternative to phalloplasty for Transmen. With the effects of testosterone treatment, the Clitoris enlarges, over time, to an average of 4–5 cm. In a metoidioplasty the enlarged clitoris is released from its position and moved forward to more closely approximate the position of a normal penis. In some cases the urethra is lengthened to end at the tip of the neophallus. The clitoris and penis are developmentally homologous organs.
