Answer from: Raúl Olivares, MD
We would usually recommend transferring one embryo after PGS. It’s true that with PGS, we are not going to fix any of the problems that the embryo may have, but by discarding those that are genetically abnormal, we are going to increase the live birth because of the risk of having a miscarriage is going to be much lower. It’s an extra way of confirming that the embryo is not just pretty but is also genetically normal, and the implantation rates and the ongoing pregnancy rate is going to be much higher.
We think that regardless of the patient’s age when we have confirmed that the embryo is genetically normal, the single embryo transfer is absolutely recommended.
