Day 2 - Quiet development

Day 2 - Quiet development

What is happening?

The fertilised eggs should by now have formed a four cell embryo.  We do not check the embryos routinely using a microscope on day two as we do not want to disturb your embryos unnecessarily. They are much better left alone in the incubator to develop as well as they can in most cases. 

If your treatment involves the use of Embryoscope time lapse technology, then we do things a little different. Visit our section on Embryoscope to see how it works and what we do with it.

In some situations, there are reasons why we might need to check on day two.  We use the standardised national scheme to grade each embryo. This allows us to give you an indication of their quality. Each embryo is an individual and we don’t expect all of them to be top grade, it's normal to have a mixture of grades. 

What should I expect?

People routinely become pregnant using embryos we have not graded highly so do not be downhearted if we have not graded your embryos as top quality. The main thing is that they are healthy and continue to develop well over the next 4 days.
