Once your eggs are collected, they spend the next few days in the care of our embryology team. Here is what happens behind the laboratory door.
Day 1: fertilisation check
The morning after collection, embryologists check each egg for signs of normal fertilisation and call you with an update.
Days 2 and 3: cleavage stage
Healthy embryos divide into four, then eight cells. We monitor growth in incubators that mimic the conditions of the body.
Days 5 and 6: blastocyst
By day five, the strongest embryos form a blastocyst with an inner cell mass and an outer layer that will become the placenta. This is usually the best stage for transfer or freezing.
