The Future of Fertility: Lab-Grown Eggs and Sperm Could revolutionize Parenting
Imagine a world where you could have a baby with yourself or in a “multiplex” parenting arrangement involving three or more individuals. While this might sound like the plot of a dystopian novel, it’s a scenario being seriously considered by the UK’s fertility watchdog, the Human Fertilisation and Embryology Authority (HFEA). The technology at the heart of this discussion is in-vitro gametes (IVGs)—eggs or sperm created in a lab from genetically reprogrammed skin or stem cells.IVGs are being hailed as the holy grail of fertility research. They promise to remove age barriers to conception and could enable same-sex couples to have biological children together.Though, this groundbreaking technology also comes with unprecedented medical and ethical risks. The HFEA is now calling for these risks to be addressed in a proposed overhaul of fertility laws.Peter Thompson, chief executive of the HFEA, emphasized the potential of IVGs: “In-vitro gametes have the potential to vastly increase the availability of human sperm and eggs for research and, if proved safe, effective, and publicly acceptable, to provide new fertility treatment options for men with low sperm counts and women with low ovarian reserve.”
The possibilities don’t stop there. IVGs could also enable more radical concepts like solo parenting and multiplex parenting. julia Chain, chair of the HFEA, quipped, “It feels like we ought to have Steven Spielberg on this committee,” highlighting the surreal nature of these discussions.
Lab-grown eggs have already been used to produce healthy mice, including ones with two biological fathers. While the equivalent feat has yet to be achieved with human cells, US startups like Conception and Gameto claim to be closing in on this milestone.
The HFEA estimates that IVGs could become viable within two to three years—though some clinicians believe it could take up to a decade.Nonetheless of the timeline, many experts predict that IVGs will eventually become “a routine part of clinical practice.”
However, important hurdles remain. The clinical use of IVGs is currently prohibited under UK law, and proving their safety is a major challenge. Any unintended genetic changes to lab-grown gametes would be passed down to future generations, raising serious concerns.
The ethical implications are equally complex. Solo parenting—creating both the egg and sperm from the same individual—poses a significant risk of recessive genetic disorders. Frances Flinter,emeritus professor of clinical genetics at King’s College London and an HFEA member,explained,“In a way,it’s the complete extreme of incest. And that is why it is so dangerous and why nobody would ever consider that to be a safe thing to.”
The HFEA has unanimously agreed that solo parenting should be banned.

The Future of Parenting: Multiplex Families and Ethical dilemmas in Fertility Science
The landscape of family structures and reproductive technology is evolving rapidly, with groundbreaking advancements like multiplex parenting and in vitro gametogenesis (IVG) challenging traditional norms. These innovations, while promising, raise significant ethical questions that demand careful consideration.
What is Multiplex Parenting?
Multiplex parenting is a novel concept where two couples produce two embryos, and cells from these embryos are used to derive eggs and sperm in the lab to create a final embryo. Unlike traditional methods, this approach does not pose the same biological risks and has a social precedent in the form of blended families or relationships with non-anonymous donors.
Rebecca Taylor, the HFEA’s scientific policy manager, explains: “in the final embryo, the four parents would actually genetically be the child’s grandparents. The parents would be an embryo, if that makes sense.” This process could redefine familial relationships and open new possibilities for couples struggling with infertility.
Ethical Concerns and Regulatory Challenges
While multiplex parenting offers hope, it also introduces ethical dilemmas.One major concern is the ability to create vast numbers of embryos in the lab, enabling extensive genetic screening.In regions with less stringent regulations than the UK—where screening is limited to serious disease-causing mutations—this could lead to a form of eugenics, where desirable traits are selected.
Additionally, the reduction in age barriers for parenthood could result in higher-risk pregnancies for older mothers and children born to much older parents. These challenges highlight the need for robust regulatory frameworks to ensure the responsible use of emerging technologies.
The Role of IVG and Future Legislation
In vitro gametogenesis (IVG), a process that creates eggs and sperm from stem cells, is another area of rapid progress. though, its application in treatment remains uncertain. Peter Thompson,CEO of the HFEA,emphasizes the importance of regulation: “Research on IVGs is progressing quickly but it is not yet clear when they might be a viable option in treatment. IVGs raise critically important questions and that is why the HFEA has recommended that they should be subject to statutory regulation in time, and that biologically dangerous use of IVGs in treatment should never be permitted.”
The HFEA’s recommendations aim to future-proof the HFE Act, ensuring that advancements in fertility science are guided by ethical principles and legal oversight.
