Historically....

..embryo transfer following IVF or ICSI took place two or three days after egg collection when the embryo contains around 6-8 cells

Blastocyst advancement today

Laboratory advancements have delivered knowledge and improved success rates for pregnancy. 

We now culture embryo's for five to 6 days to develop a blastocysts containing 80-100 cells, allowing the opportunity to prove their development potential, free of damage.

Some fertilised eggs will arrest ( stop developing) prior to day 5.  This natural selection enables the embryologist to more accurately choose the best embryo for transfer and the most likely chance of pregnancy.
