After collection, the eggs and sperm are brought to the laboratory where the
eggs will be fertilised and the embryos cultured for 5 days.
In conventional IVF, about 50,000 to 100,000 washed sperm are left in a small
plastic dish with the eggs. The sperm spend the next few hours getting through
the layers of cumulus cells, and hopefully one sperm will successfully fertilise
the egg.
By the next day - some 15 hours after introducing the sperm to the eggs - the
scientists will check to see if the eggs have fertilised by looking for the
presence of pronuclei. In normal fertilisation there should be 2 pronuclei - one
from the sperm and one from the egg.
