Top surgery for transgender men and nonbinary people is a procedure to remove breast or chest tissue (subcutaneous mastectomy). It’s also called masculinizing chest surgery.
If your chest size is small, you might be able to have surgery that spares your skin, nipple and areola. This type of surgery is called nipple-sparing subcutaneous mastectomy. If you have a larger chest, you might need to have your nipples and areolas taken off, resized and placed back into position.
Top surgery for transgender men and nonbinary people might be done as a step in the process of treating discomfort when gender identity differs from sex assigned at birth (gender dysphoria). The procedure can help transgender men and nonbinary people transition physically to their self-affirmed gender.
