Though hormone replacement therapy (HRT) is not a requirement for surgery, it can have a positive effect on fat redistribution and changing someone’s gluteal shape. For patients whose transition process involves HRT, we recommend that you wait until at least a year has passed on hormones before undergoing a body contouring procedure. Still, many patients experience difficulty with reducing or increasing fat reserves around the hips, legs and buttocks with HRT, exercise and diet alone. This is why even with hormone usage, some find it necessary to undergo a body contouring procedure to feel aligned with the shape of their bodies.
