Following hormonal treatment, the next step is usually top surgery (chest surgery). There are many different methods for performing this surgery, and is often determined by the results you want, and the size of your breasts. Your therapist will be able to put you in contact with a surgeon.
Drawbacks are that small deposits of fatty tissue may remain in the chest or the finished areola may be too large in comparison with the typical male chest. Advantages are little or no apparent scarring, and retention of nipple sensation.
