19The mathematics are a bit more complicated than this preliminary calculation suggests because PGT is more accurate with some categories of genetic disorders than others. Recessive conditions where both parents are heterozygous for the particular disorder, for example, would be statistically easier to identify than a dominant condition where one parent is a heterozygous carrier and the other is a noncarrier.

A Review,” Journal of Ovarian Research 10 (2017), https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5368937/. A major review of 455 publications on genetic screening, published in March 2017, asserted there was a higher than appreciated rate of false positives when screening early-stage human embryos for genetic abnormalities, because both cells with these mutations were spread unevenly across the embryos and because doctors didn’t fully appreciate the ability of the embryos to self-correct.

A 2010 study was far more aggressive in its estimates of the cost savings that would come from using PGT to prevent cystic fibrosis. Claiming that the average additional cost of care for a person with CF was $63,127 for an average life expectancy of thirty-seven years, the authors estimate the cumulative savings over thirty-seven years as $33.3 billion, a far larger number than mine. Additionally, according to the authors, “a total of 618,714 cumulative years of patients suffering because of CF and thousands of abortions could be prevented.” These higher estimates strengthen the cost-benefit case for universal embryo screening.

40I recognize that the widespread adoption of preimplantation embryo screening to date has been less than might have been predicted. This is likely because the procedure is in its early stage of development, expensive, and not covered by insurance in many jurisdictions, and because medical and social norms are still evolving. It may be that some jurisdictions adopt PGT at different rates, but it is my contention that adoption rates will increase over time everywhere, with the biggest jumps in places like China.
