This is my first IVF cycle. They retrieved 31 eggs. The day after ER, they told me only 4 naturally fertilized and asked me whether I wanted to do ICSI. Mind you, this was definitely over 24 hours after the retrieval (retrieval at 11 AM, call about ICSI around 1-2 PM next day). I said of course. The embryologist didn’t say it was rescue ICSI and actually told me the fert. rate is 70%. Well, later in the day, they told me 2 more fertilized naturally, and that there were 21 eggs on which they were trying ICSI (now I know rescue ICSI). I received a call today, day 2, that only 7/21 successfully fertilized with rescue ICSI.
Now I am reading about how miserable pregnancy success rates are with rescue ICSI. I should say that my husband has really good sperm count and there was never any discussion of morphology. Even telling me a 70% fert. rate is wrong-rescue ICSI has a much lower fert. rate.
My questions are whether they should have split from the beginning half of my eggs to immediately do ICSI (not rescue ICSI), or is this normal, that a clinic sees what happens with the first IVF? Will they be able to detect morphology problems that they could not previously detect with just IUIS? I feel a bit cheated, like they should have done the ICSI quicker, I even read that ICSI at 6 hours is better than ICSI at 22 hours.
