Does the quality of the gametes influence the decision on the number of embryos to be transferred?

By Marta Barranquero Gómez.
Last Update: 12/10/2020

The answer is yes. If the gametes (eggs and sperm) are of poor quality, it is most likely that the embryos generated in the laboratory would be of low quality. Therefore, these embryos may even present chromosomal alterations that would pose a risk of failure of the fertility treatment.

On the other hand, if donated gametes are used, the quality of the embryos will be higher and, therefore, the possibilities of pregnancy will increase.
