The amount of fat to be removed by liposuction and grafted to your buttocks is decided between you and the doctor at the time of your consult, and only by reviewing the areas you want worked on. 

There are no hard-and-fast mathematical amounts and it’s dependent upon your body and the results you’re going for. In general, 30 to 40% of the total amount of liposuctioned fluid and aspirate can be transferred back. For example, if you have 4500cc of liposuctioned aspirate, you will have approximately 1500cc of fat available for transfer back into the buttocks or breasts.
