I am really sorry to read this. ICSI won't fix anything unfortunately. It is like looking for a needle in a haystack and hoping you pick a "good" sperm. It can happen of course and the more eggs you have to try, the better your chances of the embryologist picking a good sperm. It is a numbers game: how many times can you endure IVF waiting for a good sperm to be IcSI'd with the egg? Obviously that answer is different for everyone. There is a procedure called PICSI that can help. It is a special medium that is "like" an eggshell and the best sperm are attracted to it. The embryologist would pick those sperm to inject. With regular IcSI the embryologist cannot see which sperm are the most highly fragmented and that is why it is so hard.
One of the girls on the FB board just got two AA blasts despite her DH's high frag %. She is still in the 2WW but we are hopeful for her that a good one was found(she did use donor eggs though as hers were questionable.
Vitamins may help reduce the frag. Get him on them ASAP. I was looking at proceptin(google it, it is expensive though but a girl on the DE checkin said it helped her DH's frag level immensely. A cocktail I was told was Vit c 500mg/ 2x day, Vit E 400mg 2x per day, proxceed(very pricey) one lack per day, pycngenol 100mg 2x/day
