Embryologists examine aspirated follicular fluid to isolate and identify mature eggs.

“They look under the microscope and try and isolate the egg. Okay. So, how long does that procedure typically take? Half an hour. Okay. and you've got the embryologist next to you and he or she is under the microscope going check check check and he or she is validating that you indeed are getting ripened eggs and they look different presumably right like those are easy to identify under a light microscope basically they tell us they got eggs we don't know if they're mature yet we know nothing about them yet I see but long we get the eggs they go to the lab and then the rest of the process happens there.”
