I used to be with Sydney IVF out of Coffs Harbour and i did have this talk with my FS - he did tell me that after 43 they will put back 3 - but i do believe its up to the FS and you to discuss - its not common practice but its not against any laws. I think alot of the time the FS makes the final decision. I strongly believe that at this age you should be allowed to put 3 back if possible and if you have 3 good embies.
