I suspect that he was referring to my specific situation. At the point where he'd said that I needed a frozen blast, I'd done two stim cycles and got quite bad OHSS with both. I'd had a total of 11 blasts frozen, but had a lot fail to thaw. Only 4 of those 11 blasts had been able to be transferred and from those 4 blasts I had three miscarriages. He'd decided that my body just liked to hyperstimulate and suggested that I just get used to getting very sick with each egg pick up and having all my embryos frozen. He also suggested that we had some chromosomal issues leading to the thaw failures and the miscarriages (one at 9 weeks the others very early) but when we asked about PGD he said it couldn't check enough chromosome pairs to be confident that it would fix the problem and that we should just rely on freezing and thawing to weed out a lot of our crap embryos and hope we eventually got one that would implant and go on to give us a successful pregnancy.

But in another appointment - the miscarriages and thaw problems were down to crap eggs which were crap because of the OHSS and that we needed to avoid OHSS and improve DH's sperm as much as possible (low count, poor motility and complete crap morphology)...

Personally - I suspect he had no idea at all and was just spinning theories to keep me happy. He did keep working towards avoiding OHSS or at the least trying to minimise it as much as possible, and we did eventually get there.

But I'd also consulted with a few other specialists - and David insisted that I stop metformin with a positive pregnancy test (but stopping metformin coincided with my first miscarriage) and that I didn't need aspirin (but we only had successful implantation when aspirin was added)... and that the prednisone I was taking for the arthritis was completely irrelevant to the conception situation (but if I reduced my prednisone dosage below 10mg while pregnant I would bleed).

Happy to have others take what they can from my experience, just glad that I can help. I honestly didn't believe the diet would work - but just did it in order to be able to tell him "told you so!", but to my complete surprise, it ended up being him telling me. However, I think the other meds had a role to play as well (I've got a few other health problems which make me a unique and complicated situation) and I never was brave enough to tell him that I was following another doctor's instructions in relating to them!
