@Charlie74 - he just said he'd been to a recent conference where based on the evidence studied, there wasn't any advantage in using the HAICSI and then added that I shoild save the $700 or whatever and not do it. The fact that he told me that in the context of my below average fert rate with ICSI and the fact that he knows the costs isn't a factor in my decision, suggested to me that he really doesn't think it improves fert rates. But now I'm thinking, if it doesn't do any harm, why not just do it if there's even a slight possibility of it improving fert rate. I am nervous about not using it and screwing up my last ever cycle by getting an even worse fert rate than I usually do. I'm going to talk to my FS a about it after Easter when I have my first scan in the cycle. From what I can see Genea and Melbourne IVF both have the special microscope to do IMSI.
