UK's Three-Parent IVF: Breakthrough for Eight Healthy Children
Imagine the powerhouses of your cells, called mitochondria, are broken, causing a disease.
Scientists in the UK have created a new way to help moms with this problem have healthy babies.
They use a special IVF technique with three parents: mom, dad, and a donor.
This helps replace the broken powerhouses with healthy ones.
The babies get almost all their genes from mom and dad, with just a tiny bit from the donor.
It's like fixing a car's engine to make sure the baby is healthy, but it's a complex process with some ethical questions.
Eight children have been born in the UK using a three-parent IVF technique.
The procedure uses genetic material from the mother, father, and a mitochondrial donor.
This technique prevents the transmission of incurable mitochondrial diseases.
The procedure involves either pronuclear transfer or maternal spindle transfer.
Ethical concerns exist, but the technique is viewed as a life-saving intervention.
