Mastectomy is usually the first and most important surgical procedure in female-to-male (FTM) individuals with gender identity disorder. Nipple reduction is also important in the process of reconstructing the chest wall for a more male appearance. If the nipples remain large after a mastectomy, the results may be disappointing to many FTM transsexuals. Nipple reduction enables these individuals to go to the beach or Japanese public baths, where they may go topless in public. We therefore consider that nipple reduction is indicated for all FTM transsexuals who desire it. There are a variety of methods for the reduction of enlarged nipples for women or non- FTM patients, but only a few reports have described the process used to create masculine-appearing nipples for FTM transsexuals. We developed a novel technique called the Eryngii method for creating male-like nipples using a 4-mm diameter dermal punch knife. The name of the method refers to the Eryngii king trumpet mushroom, which the nipple resembles after the surgical process. The main strength of this method is that it permits the creation of ideal nipples without difficulty. Here we introduce the technique and discuss our history of surgical methods for nipple reduction, including improvements and elaborations.
