If you're considering using PGT-A / PGS "genetic screening" within an Egg Donation Program, you may look at an example of IVF packages in Spain - where preimplantation genetic tests are included in the program:

• Egg Donation Premium Genetics Program
  10 fresh donor oocytes and 5 embryos on day 5 are guaranteed,
  all IVF techniques are included in the Package (ICSI, MACS, Embryo Monitoring, Blastocyst culture, Vitrification of (remaining) embryos and storage for 1 year, Donor Genetic Screening and many more... )

• Egg Donation Premium Genetics Frozen Eggs Program
  same as above, frozen eggs from the donor are used.

 PGT-A / PGS is also available for IVF with own eggs Programs.
