Thank you for the question. Hormone therapy may be an option for you. However, the most predictable way to increase breast size would be through breast augmentation surgery. I have had the opportunity to work with several men interested in breast implants ( to feminize the chest wall). This is a different situation from trans gender patients in transition and from men who are looking to augment their chest walls ( pectoralis implants). Nevertheless, this subset of patients is somewhat uncommon; it is very important to understand patient motivation clearly and to educate these patients about the long-term effects of having feminized chest walls. Best wishes.
