Hereditary diseases haven't touched my family yet, and for that, I'm grateful. But imagine discovering you or your partner carries one. How far would you go to ensure your children are free from it? What do you think about culturing embryos specifically for research?

If you suspect you or your partner may carry a serious hereditary condition, genetic testing can confirm it. If positive, your options include: taking the risk and prenatal testing, opting out of biological children to avoid the risk entirely, or using preimplantation genetic diagnosis (PGD) to select only healthy embryos for implantation.
For severe conditions, no prospective parent wants to pass on such a burden. While medical advancements offer ways to prevent hereditary diseases, the decisions remain profoundly challenging.
In 2016, former Health Minister Edith Schippers granted researchers permission to culture embryos under strict conditions. The goal? Ultimately enabling infertile individuals—due to cancer treatments or congenital issues—to have children, and helping those with serious hereditary diseases avoid passing them on. Since surplus IVF embryos from other couples (with consent) can't serve these patients, lab-cultured embryos are essential.
The Health Council now advocates expanding this to broader research, including gene-editing techniques to replace faulty DNA. This could prevent diseases like Duchenne muscular dystrophy, cystic fibrosis, or Huntington's from being inherited.
No parent wishes severe illness on their child, yet this approach sparks debate. For some, an embryo represents human life from conception, making its use in research unacceptable. Researchers, however, focus on early-stage embryos—just a millimeter wide with a few hundred cells. Cell fates (skin, heart muscle, etc.) aren't determined until weeks later.
Interest centers on pluripotent stem cells, emerging four days post-fertilization. Regulations limit research to 14 days after fertilization. To some, these are mere cells, not yet a person; to others, even this stage crosses an ethical line. Regardless, potential breakthroughs could transform lives.
Saskia Buijs, mother of two sons living with an energy metabolism disorder, speaks from firsthand experience. I previously shared their poignant story: Saskia, Max, and Jip battle a chronic, progressive mitochondrial disease affecting energy production.
Two children are diagnosed weekly in the Netherlands; half die before age 10, with only 70% reaching adulthood. It strikes unpredictably—from infancy to later life mildly—and ravages vital organs.
Max and Jip are bright boys requiring round-the-clock care, including nighttime ventilators. A cold or choking episode can prove fatal—they live on the edge. Saskia strongly supports embryo culturing for research: "Would I do it? Absolutely, no hesitation. It could mean a healthy child. Those debating ethics endlessly don't have two affected children!"
