Looking at your cycle record, I agree, no ICSI. This cycle, I had 15 eggs collected, 9 mature and only 5 fertilized, the lowest fert rate ever using ICSI for the 1st time. In the past, my fert rate using IVF has always been around 80%. I remember BW mentioned in some past post, ICSI could have potential demaging the spiral of the egg structure. So it is not neccessarily the more invasive the better.

Another thing I learned was from Day1-3, it is more likely to be egg quality issue, and from D3-5, it is usually sperm DNA kick in. So by the look at yours, increasing egg quality is the key. Have you thought about Antagonist cycle? this is the kind of cycle usually suggest to people who have lot of eggs but seeking better quality, or at least that was the reason when it was first suggested to me. But obviously it also depends on different individual, it didn't work for me. I do know a lot people change to different protocle and that was the trick they needed. I am not an expert on this but maybe worth asking your FS about it?

Just to make it so much easier (yeah right), I do agree that our body sometimes can be very unpredicable and every cycle can be so different too. It doesn't make thing easier does it?

If you feel that extra vitmins helped your for that excellent cycle, probably keep it up. Maybe adding in Royal Jelly to the mix as well as it is a major fertility booster. Fish oil and CQ10 is also helping and I know some ladies in PGD thread used to take DHEA to improve egg quality, but I haven't had any experience on it.

Food for thought anyway. HIH.
