Hi Saraz, sorry to hear that you are having troubles with your clinic. And also sorry to hear that the meds aren't treating you too well. I was lucky that I didn't have any side effects from the meds, except a little nausea on the progesterone gel. Hopefully this cycle goes well for you and you don't have to go through multiple cycles with these sort of symptoms.

With regards to how many eggs get fertilised, I'm sure I filled out a form where you could choose how many to fertilise. They are your eggs and your partner's sperm, so it's really your choice. Having said that, I'll let you know what our experience was. It took us two cycles to fall pregnant with our little one. First cycle I had 10 eggs, 7 fertilised and all were big enough for biopsy on day 3 (we had PGD done). Of the 7, one had a fragmented nucleus, one they couldn't get pgd results for, and all of the remaining 5 had chromosome abnormalities that were "incompatible with life". I was shattered and shocked at the news. I had no idea that we would have such a high number of embies with chromosome problems considering I'm only 30 and healthy. Second cycle my meds were increased slightly and they managed to get 21 eggs. 20 were suitable for fertilisation, but only 11 fertilised, and 10 of those made it to biopsy. Of the 10, two had no nuclei (therefore no chromosomes), 7 had chromosome abnormalities, and we had one very precious little healthy girl embryo. She's a strong little one and we are now almost 10 weeks pregnant with our little Apple Blossom.

I was amazed how common chromosome problems are. The scientist in the PGD lab told me that on average they probably find at least 50% of embryo's at day 3 have chromosome abnormalities. I worried that the IVF process maybe creates more problems, but she assured me that that was not the case. She said that the rate is the same if you are conceiving naturally, and that these embryo's usually either do not create a pregnancy or miscarry very early.

I guess what I'm trying to say that it is going to be a hard decision for you to decide how many eggs to fertilise because it's very hard to know how many healthy embryo's you might get from any number of eggs. It took 31 of my eggs to get my one healthy embie. I hope the decision isn't too stressful for you, and I wish you all the best for the rest of your cycle!
