PGT-A

Hi! Currently have 10 fertilized embryos and will be doing PGT-A testing through Cooper Genomics. Need to much researching and can’t get the negative of this test out of my mind- damaging of embryos, long term affects. I am 36 years old, no history of miscarriage, MFI. Can anyone shed some light with this? I also feel that our clinic/RE wouldn’t provide this test if was all true?!
