600cc Silicone on a Transgender Woman? Size Suggestions?

Thanks for your question.I prefer to use MemoryShape breast implants for natural but big. I recently used a 615 cc TM+ in a similar situation as you have described for a great results. Ask your surgeon about these breast implants or you can make a consultation with me online. You can also see the shape breast implants before and after in the photos linked below.Best wishes, Dr. ALDO

It is best to seek the advice and consultation of a board certified plastic surgeon who specializes in MTF top surgery to give you the appropriate recommendations for implant size

Have you considered a shaped implant.  I've found that in my transgender patients with minimal amounts of native breast tissue, they tend to give a better, more natural shape.
