Jilly, I speak to a lot of Americans doing IVF and many of them use a drug called Menopur which is a combination of FSH and LH, rather than just straight FSH. I asked my old Dr about it for our last IVF cycle and he said it wasn't available here but we could do low dose HCG during the stimming phase instead. Since LH and HCG are similar in structure (which is why we use HCG for a trigger as a substitute for our natural LH surge) that seemed a logical alternative. We didn't end up doing it though. The reason I asked about it was because I'd read that it can work better for poor responders (which is what I am) than just straight FSH. Your Dr may expect you to be a poor responder due to your age and be taking steps to maximise the chances of your cycle succeeding (which sounds great to me!).
