Once the eggs have been retrieved, they are placed in a
petri dish and then the man’s swimmers are added as well. They are then
incubated together. This give the sperm a chance to fertilize the eggs and then
for the eggs to split and start growing.
“The next day, called "Day 1" in the lab, the eggs
will be examined under a microscope to determine whether fertilization has
occurred. If it has, the embryos will be ready to transfer into the uterus within
2 to 4 days of "Day 1." (http://bodyandhealth.canada.com/fertility/Details.aspx?channel_id=2048§ion_id=1016&article_id=4452&article_type=2)
