Lou, letrozole is some funky drug that my FS is going to try to use to get me to ovulate. He seems to prefer it to clomid these days (he used clomid for a friend of mine a couple of years back), and it's only PBS approved for the treatment of post-menopausal breast cancer. From the information I've found it's relatively new, and the doctors seem to either love it or hate it. It effectively does the same thing as clomid - you take it for 5 days at the start of the cycle, and then sit back and wait, but it works on a completely different mechanism in the body so we're hopeful it's not going to cause the same anxiety problems as clomid did for me. It's basically the only way I can do a natural cycle, and he says he gets better pregnancy rates with natural cycles, so we're giving it a shot. Although, this cycle is just the test to see if it will work for the FET. Praying real hard that it does!
