What is embryonic aneuploidy?

Embryonic aneuploidies refer to chromosomal alterations in embryos. An aneuploidy consists of an imbalance in the number of chromosomes and is quite common in human embryos. In particular, one in three embryos presents aneuploidies originating during the formation of the gametes or after fertilization.

The age of the woman is a risk factor for embryonic aneuploidies. Therefore, as maternal age increases, the greater the probability of obtaining embryos with some chromosomal alteration.
