The embryology laboratory is where technology makes the greatest difference. Continuous monitoring of the embryos, support for implantation and genetic testing before embryo transfer increase the accuracy of selection and, ultimately, the chances of a healthy baby being born.
What they involve
- Time-lapse technology: uninterrupted recording of each embryo's development, without disturbing the culture conditions.
- Assisted hatching: thinning of the zona pellucida to make implantation easier, for selected indications.
- Preimplantation genetic testing (PGT): detecting chromosomal or genetic abnormalities before embryo transfer.
None of these techniques is used routinely. They are used when there is a clear indication and when the expected benefit outweighs the additional intervention on the embryo.
