Just went throught the whole ICSI versus IVF saga. Lying in bed after an EPU of one, the lab manager strongly urged I do IVF. Im using donor Xytex sperm which is excellent quality. She said the lab has been running a lot of analysis which shows for women over 40 to definitely NOT use ICSI. There is the chance of damaging the egg, or even completely shattering it. They said that ICSI was designed for sperm issues, if you dont have them, and your egg quality is iffy as part of your age, then dont use it. This will now become the trend apparently. My egg took almost 24 hours to fertlise but the little buggers finally cracked that hard stubborn old egg. It was a tough decision for me, but Im glad I made it, and now Im praying for the next 14 days its going to work.
