An unconventional approach to reproduction is reportedly reducing the risk of metabolic disease.Three-person in vitro fertilization (IVF), a new concept developed by scientists in New Castle, U.K., has resulted in the births of eight healthy children.In the study, published in The New England Journal of Medicine, the researchers found that pathogenic variants in mitochondrial DNA (mtDNA) are a “common cause” of severe — and often fatal — inherited metabolic disease.SPERM DONOR’S GENETIC MUTATION LINKED TO CANCER IN 10 CONCEIVED CHILDRENThis DNA in the mother’s mitochondria can cause “harmful mutations” in children, which can lead to diseases that affect tissues in the heart, brain and muscles, according to the journal Nature. A three-person IVF technique has led to the delivery of eight healthy babies in the U.K. (iStock)At the Newcastle Fertility Centre, 22 women with pathogenic mtDNA variants underwent a “pronuclear transfer,” in which they received a mitochondrial donation.This involved the transfer of the nucleus of a fertilized egg with “faulty mitochondria” into a donor egg cell with healthy mitochondria, Nature detailed.MEN FACE DOUBLE DEMENTIA RISK IF THEY HAVE A HIDDEN GENETIC MUTATIONThe result includes nuclear DNA from both the biological mother and father, as well as mitochondrial DNA from the separate egg donor.From this, eight children were born healthy, with no levels or low levels of mtDNA detected in their blood. The approach involved the transfer of the nucleus of a fertilized egg with “faulty mitochondria” into a donor egg cell with healthy mitochondria. (David L.

This new science will “empower more couples to pursue safe and healthy pregnancies,” noted a Columbia fertility expert.
