flag Australians use flawed genetic embryo tests during IVF for traits like intelligence, raising ethical and accuracy concerns.

flag Australians are increasingly using unproven polygenic risk score tests during IVF to predict traits like intelligence, height, and disease risk in embryos, despite expert warnings about their inaccuracy and ethical concerns. flag Offered by U.S. companies like Nucleus Genomics and Herasight, these tests analyze thousands of genetic variants to rank embryos, with some patients testing dozens abroad to select for higher predicted cognitive ability and health. flag Critics say the results are unreliable, influenced by environmental factors not accounted for, and less accurate for non-European ancestry due to biased genetic databases. flag Major medical groups oppose the practice, warning it risks promoting "designer babies" and echoes eugenics, while demand continues amid claims of improved health outcomes.
