Scrotoplasty, also known as oscheoplasty, is reparative or plastic surgery of the scrotum.
As part of the surgical options for trans men, scrotoplasty is one of several operations performed to transform/reform the external genitalia into a penis and a scrotum.
In this procedure, the labia majora (see vulva) are dissected to form hollow cavities, and united into an approximation of a scrotum. The surgeon may or may not deploy some sort of tissue expansion prior to the operation if there is insufficient skin tissue. Afterwards, silicone prosthetic testicles can be inserted to fill the new scrotum to enhance the look and feel.
