IVF breakthrough: novel DNA test could boost success rates
"In the US, the majority of women undergoing in vitro fertilization have a success rate of 20-35%. Now, researchers have created a test that they say could boost success rates to as much as 80%.
The test, called MitoGrade, works by measuring the
levels of abnormal mitochondrial DNA present in embryos, allowing doctors to
determine which embryos are most viable for a successful pregnancy.
Mitochondria
are structures found within cells that are responsible for generating the
energy cells need to function. Each mitochondrion contains small amounts of
DNA, known as mitochondrial DNA.
It
emerged in recent years that the number of chromosomes in an embryo can
influence the outcomes of in vitro fertilization (IVF). But more recently,
researchers from the University of Oxford and genetics laboratory Reprogenetics
- both in the UK - found that the levels of mitochondrial DNA in embryos is a
key factor in IVF success..."
