In the U.K., scientists are exploring a groundbreaking method to conceive babies using genetic material from three people. This initiative, championed by prominent medical officials, aims to help couples prevent rare genetic disorders from being passed down to their children.
The proposed technique focuses on mothers with defective mitochondria, which can lead to conditions such as muscular dystrophy, epilepsy, and other severe health issues. Currently, about 1 in 200 children are born with mitochondrial disorders each year. By utilizing DNA from three sources, the hope is to lower this statistic significantly.
How the Process Works
Here’s how the process works: scientists will extract healthy genetic material from the mother’s egg, then transfer this into a donor egg from a woman with healthy mitochondria. The donor egg’s original DNA gets removed, allowing the fertilized embryo—now containing the mother’s healthy genetic material—to be placed back into the mother’s womb.
The news about this innovative approach first broke in British tabloids back in 2008, but the term “three-parent baby” used in those reports has created confusion. Critics argue that the donor’s contribution is minimal and label the practice as unethical, advocating for alternatives like egg donation or embryo screening. There are also moral concerns regarding the destruction of embryos, which some view as unacceptable.
Dr. Fiona Lang, a leading researcher, noted, “These innovative procedures could help halt the transmission of these serious diseases. It’s essential that we work towards implementing this potentially life-saving treatment without delay.” Following a public consultation in 2013, the United Kingdom’s fertility authority found that a majority of people supported these advanced in vitro fertilization techniques. The director of the Genetic Alliance U.K. remarked, “Many mitochondrial conditions are so severe they can be fatal in infancy, leaving families devastated. Having another option for at-risk families is vital.”
Currently, British law prohibits altering human eggs or embryos before they are implanted, limiting these techniques to research purposes. However, the government plans to release draft guidelines soon, paving the way for potential advancements.

In summary, the debate over using DNA from three individuals to create babies is ongoing, with both strong support and opposition. As the U.K. prepares to refine its guidelines, many are hopeful that this advancement can lead to healthier futures for countless families.
