Does transplanted hair fall out years after the surgery, if so, how frequent is this?

I was told that transplanted hair is placed into a hormone sensitive area (area from hair line over the top of the head till small part at the back).  What are the chances (approx. in percent if possible) of losing the transplanted hair? how many patients are satisfied with the result 5-10 years post FUE transplatation?

I have been doing hair transplants for 27 years and have seen patient I did 25+ years ago with their results as good as it was 25 years ago. A few patients will lose their transplanted hair between 5-30 years later, but that is less than 5% of patients?. I have seen many of my patients 5-20 years from their transplants and their new hair largely remained.
