Mathematics should clarify, not obfuscate: an inaccurate and misleading calculation of the cost-effectiveness of preimplantation genetic testing for aneuploidy

Mathematics should clarify, not obfuscate: an inaccurate and misleading calculation of the cost-effectiveness of preimplantation genetic testing for aneuploidy
In this issue of Fertility and Sterility, Somigliana et al. (1) present a theoretic cost-effectiveness analysis of the utilization of preimplantation genetic testing for aneuploidy (PGT-A). Using a mathematical calculation, they compare a theoretic PGT-A strategy against a non–PGT-A mandatory single-embryo transfer approach. Their calculation stratifies the results by age and by the theoretic number of blastocysts produced in a single cycle. They calculate the cost per live birth for both PGT-A and non–PGT-A cycles by estimating the costs of each and dividing these by the cumulative pregnancy rates obtained from the Italian national registry.
