What are the risks of ICSI over conventional IVF?
Before performing ICSI, the cells surrounding the egg must be removed so it is possible to see whether the egg is mature or not – only mature eggs can be injected with a sperm. This is an additional manipulation of the eggs, but the main additional risk is of damage to the eggs during the injection procedure itself. This can affect up to 10% of the eggs injected. Current literature suggests that there is no additional risk of any genetic abnormalities in children born from ICSI over that of IVF.
