Euploid rates among oocyte donors: is there an optimal age for donation?

Oocyte donors age ≤ 25 had similar cycle blastocyst euploid rates, blastocyst formation rates, and number of retrieved oocytes compared to donors age 26-30. There was no correlation between cycle blastocyst euploid rates and age of the oocyte donor from 18 to 34 years. Given the lack of significant age-related change in cycle blastocyst euploid rates, our data support existing practices which do not favor a specific age subgroup of young oocyte donors.
