 Mitochondrial replacement therapy

Mitochondrial replacement therapy (MRT) is a reproductive technology designed to prevent the transmission of mitochondrial diseases from mother to child. Mitochondrial diseases are genetic disorders caused by mutations in the DNA of mitochondria, the energy-producing organelles in cells. These diseases can lead to a wide range of health issues, including muscular weakness, neurological problems, and organ dysfunction. MRT involves a process that replaces faulty mitochondria in a woman's eggs with healthy mitochondria from a donor.
