Grace1 - my FS was not keen on me doing anymore than 2 cycles once I'd done two cycles and got no normal embryos on PGD testing. I did a third which again produced no normal embryos. He reluctantly let me do a fourth and final cycle which produced my only normal embryo and BFP. He said the only reason he supported me doing it was because me egg numbers were high and so the chance of the roulette wheel landing on my number was higher than someone who retrieved 2 or 3 eggs. All my cycles were antagonist and all done while I was 42. I guess at our age the FS tend to throw the towel in quickly as they know how hard it is to get that golden egg. I believe that protocol affects egg quality ( as our friend Dr Sher from Las Vegas often talks about) so I think it's worth you trying an antagonist cycle. My last and successful cycle was Gonal f plus luveris which I hadn't used on the previous three cycles ( menopur only for two and Gonal f only for one).
