Many non-randomized PGS studies have been published and report an increase in implantation rate, and/or a decrease in miscarriage rate. Recently, two randomized controlled trials have been conducted on patients with AMA as the only indication. Neither study showed a benefit in performing PGS using live birth rate as the measure of success. The debate on the usefulness of PGS i..
