Fertility clinics are increasingly considering longevity factors when selecting embryos for in-vitro fertilization (IVF), sparking ethical and scientific debate in the medical community.

The Wall Street Journal reports on a growing trend in IVF where clinics are using genetic screening and other criteria to select embryos not only for viability but also for predicted lifespan and health in later life. This practice raises questions about the definition of 'best' embryo and the potential for unintended consequences. While some experts champion the idea of proactively selecting for healthier futures, others express concerns about eugenics and the limitations of current predictive technologies. The article quotes several leading fertility specialists discussing the implications of this trend. It highlights the current limitations of predicting longevity and the ethical considerations of prioritizing certain genetic traits over others. This trend signifies a potential shift in how we approach reproductive technologies, moving beyond solely focusing on successful implantation to considering the long-term health outcomes of offspring. Experts predict growing demand of selecting embryo based on longevity.
