Extended Cultivation
Extended Embryo Cultivation
On the first day of its life, an embryo has 1 cell, and during embryo cultivation, the number of cells in the embryo increases.
If we perform embryo transfer or freezing or embryo storage by day 3, the embryo optimally has 8-12 cells.
Extended cultivation enables better selection of embryos with the highest chance of successful implantation.
When do we speak of extended embryo cultivation?
If we monitor an embryo or group of embryos for longer, for a period of 5-6 days, we speak of so-called extended embryo cultivation.
What is extended embryo cultivation used for?
It serves for natural selection of embryos to which we dedicate the future through transfer or freezing.
Selection of embryos that are healthy:
- suitable for transfer into the uterus
- suitable for freezing and storage for the future or not
The second group consists of embryos that are not healthy and therefore are not suitable for transfer or freezing for the future - embryos that have arrested in division
