To produce enough enzymes for a sperm to penetrate the corona radiata and zona pellucide
511
What happens once the oocyte has been inseminated?
The fertilised eggs are left in an incubator for 2-5 and observed until the reach the blastocyst stage of development when the highest quality embryos are selected for transfer/
512
