Brief Summary:
Vienna Consensus has identified 10% damage rate after ICSI as a competency value. Despite the highest quality embryologists doing ICSI, degeneration sometimes occurs due to oocyte factors such as the fragile membrane, etc. Cytochalasin B serves to facilitate spindle or pronuclear transfer procedures helping to reduce the damage rate with no harm reported. Using Cytochalasin B during ICSI could serve to rescue some oocytes from the degeneration allowing for more chances of viable zygotes,
