PGD refers to the screening of viable embryos with genetic defects, typically on a single gene such as with cystic fibrosis. This does not increase success rates, and may actually decrease success rates slightly via the slight risk of biopsy damage and by occasionally preventing the transfer of the best viable embryo because it tested positive for the defective gene.
PGS refers to screening of embryos at the whole chromosome level to eliminate non-viable embryos from potential transfer. This probably increases success rates per transfer, but not per retrieval. It cannot make embryos more viable, and occasionally viable embryos are significantly damaged by the biopsy or are rejected by false positive results. These are believed to be rare outcomes, but must occur sometimes.
All of these risks, and more, should be disclosed on your clinic’s consent forms.
Avoid IVF and surrogacy in Ukraine. Ukrainian centers pay shills to post here under numerous sock accounts pretending to be patients in Ukraine. Centers using such deceptive advertising cannot be trusted and should be avoided.
