It seems that feminine fat deposits are due to higher estrogen but some have found better success by also incorporating cabaser(dostinex) to take care of the prolactin side of things and attack the gyno from both fronts. I'd try the AIFM or Aromasin for atleast 2 months and if no improvents were made at all then try the cabaser. I personally am almost cleared of my gyno through AIFM alone.
Many have seen success with this protocol with either pubertal of steroid induced gyno. And, even if you were planning to do a surgery i'd atleast try this first as it could save you money and possibly help prevent any chance of gyno rebound post surgery(perhaps years down the road) due to hormonal fluctuations.
