Experts have pointed out that studies claiming no ill effects of PGS on embryos are often based on testing of excellent high-quality embryos rather than more"delicate" lower-quality embryos that might suffer more. This is because the testing involves extracting cells only from the outer embryo layer that produces the placenta and umbilical cord, which is not representative of the inner embryo layer that gives rise to the baby itself.
