Abstract
Preimplantation genetic diagnosis (PGD) involves the testing of embryos produced through in vitro fertilisation (IVF) or intracytoplasmic sperm injection. One or two blastomeres are excised from the embryo at the 6- to 8-cell stage, and a genetic analysis is conducted with probes to detect heritable genetic conditions. Most commonly, only ‘unaffected’ embryos will then be transferred to the uterus in the hope of initiating a pregnancy that in all likelihood will not be affected by the familial disorder or chromosomal anomaly tested for.1 PGD was originally developed in the late 1980s as an alternative to prenatal diagnosis (PND) for couples wishing to produce a genetically related child free of an undesired, heritable, genetic condition where at least one of the prospective parents is a known carrier.2 Given that it is possible, and in the opinion of some desirable3 to utilise PGD to select against Down's syndrome embryos in the context of IVF, is it appropriate for health care professionals to offer, and society to permit, the use of this technology for this purpose? What makes this condition so ‘serious’—in contradistinction to other ‘not-serious-enough’ conditions—that PGD testing for it is deemed an appropriate intervention.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
