UK Couples Circumventing IVF Laws to Select Embryos Based on Genetic Predictions: IQ, Health & More

(Last Updated: October 26, 2023)
The pursuit of a “designer baby” is edging closer to reality in the UK, as couples undergoing In Vitro fertilization (IVF) are increasingly exploiting a legal loophole to rank their embryos based on genetic predictions for traits like IQ, height, and susceptibility to disease. While direct genetic screening for these characteristics is prohibited within UK fertility clinics, patients are leveraging data protection laws to access raw genetic data and send it abroad for analysis, sparking ethical and scientific debate. This practice raises profound questions about reproductive autonomy, genetic determinism, and the future of assisted reproductive technologies.
What’s Happening?
UK couples are utilizing a workaround to select embryos based on polygenic scores – predictions generated from analyzing an embryo’s entire genome for propensities towards certain traits. This is achieved by:
* Accessing Raw Genetic data: Under data protection laws, patients have the right to access their own genetic details, including that of their embryos.
* Outsourcing Analysis: They are then sending this raw data to companies, primarily based in the US, that specialize in polygenic scoring.
* Embryo Selection: Couples are using the resulting scores to inform their embryo selection process, aiming for embryos predicted to have higher IQs, greater height, and reduced risk of certain diseases.
Why It Matters: The Ethical and Scientific concerns
This emerging trend is causing important concern among scientists and ethicists. The core issues are:
* Unproven Science: Polygenic scoring is a relatively new field, and the accuracy of these predictions is debated. The scores are probabilities, not certainties, and can be influenced by environmental factors. [HIGH PRIORITY: Expand on the limitations of polygenic scoring. Cite scientific studies.]
* Ethical Implications: Selecting embryos based on non-medical traits raises concerns about eugenics, genetic discrimination, and the potential for exacerbating social inequalities. [HIGH PRIORITY: Expand on the ethical arguments. Include perspectives from bioethicists.]
* Legal Ambiguity: The current legal framework in the UK doesn’t explicitly address this practice, creating a “gray area” that allows couples to circumvent regulations.
* Potential for Harm: Focusing on genetic predispositions may overshadow the importance of nurturing and environmental factors in a child’s development.
Key Facts at a glance
The Role of Polygenic Screening Companies
Several US-based companies are offering polygenic screening services. Herasight, one prominent example, charges approximately $50,000 (£37,000) for assessing an unlimited number of embryos. They claim to provide predictions for:
* IQ: An average gain of six IQ points for a couple with five embryos.
* Height: Predicted adult height.
* Disease Risk: Scores for conditions including heart disease, common cancers, Alzheimer’s, and schizophrenia.
Herasight has confirmed working with couples undergoing IVF in the UK, but maintains it is indeed not in breach of any regulations. [HIGH PRIORITY: Research and include information about other companies offering similar services.]
Avenues Fertility Clinic and the HFEA’s Response
Dr. Cristina Hickman, founder of Avenues fertility clinic in London, highlighted the “legal and ethical confusion” created by advances in embryo screening and the availability of polygenic screening services. She brought the issue to the attention of the Human Fertilisation and Embryology Authority (HFEA) in a letter last month.
Avenues currently has two patients who intend to use Herasight’s services independently of the clinic.
