Topical estrogens are prescription medications that should be supervised by an expert in transgender patients. Over-the-counter estrogens are not safe for self-administration, and can cause other changes besides (minimal) breast growth, such as fat distribution changes, muscle reduction, skin changes, and adult acne. Testosterone suppression should also be part of the M-F transition process, as well as other surgical considerations. Your question stated that you are a male, for which breast implants are an option for appropriate patients. But if you are just starting your transition as part of the M-F process, there is much more than breast size to consider.Even on proper hormone therapy, most patients will see no more than 1/2 to 1 1/2 bra cup size increase, which is usually inadequate for the usually taller, larger previously-male anatomy. Breast implants provide the best, softest, and most natural breast enhancement for all patients, not just transgender patients, some of whom may require tissue expanders and subsequent implants.If you are just starting the transgender process, seek professional help. This is an arduous but ultimately rewarding process that is much more than just "growing" breasts. Best wishes! Dr. Tholen
