but I also know of several people who have used antagonist protocol and it has worked with a high FSH.
A friend of mine who is 40 recently used a surrogate and her own eggs with antagonist and another 39 OE IVF antagonist. They did however have their AMH tested as well as FSH before embarking on the expense - I think that maybe an idea for you.
Their protocol was 0.02 ml suprefact morning and night, 300 iu of gonal F and 150 iu menapur in the morning. Suprefact started on day one of period and Gonal F and menapur from day 2. As soon as the biggest follicle gets to 18/19 mm you do egg retrieval - very successful!
