Embryo screening sales revive debate over consumer-driven eugenics

In an essay published by the Guardian on 27 October 2026, Jan Grue examined Nucleus Genomics’ marketing of embryo screening to prospective parents. He described New York subway advertisements from the previous year promoting an IVF service that offered screening of up to 20 embryos for genetic disorders and characteristics including eye colour, height-related traits and longevity.

Grue argued that such marketing recasts eugenics around consumer choice rather than state coercion. He also challenged the interpretation of advertised genetic estimates for height and intelligence: population-level measures of variation do not establish that parents can reliably choose those outcomes for an individual child.

The essay draws a distinction between treating an existing person’s condition and selecting which embryo develops into a child. Grue grounds that question in his experience of spinal muscular atrophy. His argument places disability and the value assigned to different lives at the centre of a debate marketed around parental choice.
