July 11, 2016

(Med Page Today) – Embryos with higher levels of mitochondrial DNA may be less likely to lead to a pregnancy during an IVF cycle, a small prospective study presented here found. Of all the embryos with normal or low levels of mitochondrial DNA, 76% implanted successfully and led to an ongoing pregnancy compared with 0% of embryos with elevated mitochondrial DNA levels (P<0.0001), reported Elpida Fragouli, PhD, of Reprogenetics in Oxford, England, and colleagues.
