I've seen you in the Melbourne chat on BH (never participated in te chat, just stalked),hope this year brings us the babies we want. I'll be curious to see how your appointment will go. I also have (had) mild endo (removed now) and PCO. We seem to be similar with the infertility causes and in that I also average around 20 follicles (on 300 Gonal F) and I got 8 follicles on 112.5 Gonal F. My first specialist claimed we were unsuccessful because the embryos weren't chromosomally normal, which he was right, just that there's ways to improve that.
My second specialist was a bit more proactive, nicer to deal with, listened a bit more and tried different protocols, did a lot more diagnostic tests, however, despite figuring out I have bed eggs (which he declared mid 2nd cycle with him when he was thinking out loud what trigger to give me to improve egg quality), he hasn't suggested anything being done to improve that. So I did 2 more stim cycles and still no BFP. All up I've done 6 stim cycles, 3 of which were PGD ones and if I haven't done the PGD testing, I'd still be cycling with the embryos that didn't stand a chance...
FYI, on 300 or 112.5 Gonal I averaged 4 blastocycts, but only one of these generally grew at a desired rate, all other arrested on or after day 5. From 3 PGD cycles, the "good" embryo was genetically normal twice and not the third tome....
It does seem that more Gonal scrambles my eggs, but then we tried a low stim protocol, that also hasn't resulted in pregnancy, so I don't know what's going on. I hope Lynn will be able to shed some light.
Let me know how you go.
