2 days after In Vitro Fertilisation

What can be observed two days after in Vitro Fertilisation?

Forty-eight hours after IVF, the first embryos can be observed. As in people, no two of them are alike. Each embryo has its own features and, at this stage, it can already be divided into 2, 3, 4 or 5 cells. Not all embryos show the same quality even in the same cycle.

We consider an embryo good on the second day if it has four same size cells with fragmentation percentages no higher than 10-15%.
