The UK's IVF system has been exploited by couples to gain insight into their embryos' potential intelligence quotient, height, and other physical traits. The practice, known as polygenic embryo screening or PGT-P, is not currently permitted under the regulations governing fertility treatments.
Polygenic testing in embryos is possible through the analysis of genetic data, including genome sequencing, which can reveal sex and provide predictions for various traits. However, this technology faces controversy due to concerns over accuracy and the ethics of using such information to guide reproductive decisions.
Complex traits like intelligence are influenced by multiple genes with differing effects, making it difficult to predict an embryo's likelihood of developing certain conditions. The algorithms used in polygenic testing rely on vast genetic databases but offer probabilistic predictions rather than certainties.
Some advocate for PGT-P, citing potential health benefits and a parent's right to make informed choices about their child's genetics. Nevertheless, experts emphasize the need for further research into the accuracy of these tests within the context of embryo selection.
Regulatory bodies have expressed concerns that using such technology without thorough validation may lead to premature adoption of untested methods. As genetic sequencing becomes more accessible, it is essential to address these issues and establish clear guidelines for its use in fertility treatments.
Critics argue that polygenic scores are overly simplistic, capturing only a small fraction of the complex genetic factors influencing traits like intelligence. By adopting PGT-P without rigorous testing, parents may be subjecting themselves and their children to potential risks or false hopes.
The debate surrounding polygenic embryo screening highlights the need for nuanced discussions about the ethics of reproductive technologies and the responsibility that comes with using them.
