New DNA Test Is Basis for Groundbreaking IVF Refund Plan, Easing Financial Burden for Patients
... (referred to as "aneuploidy") will result in either a non-viable embryo, a miscarriage or, if implanted and carried to term, a birth defect. Because aneuploidy
is the most common cause of IVF failure, identifying viable embryos for transfer to the uterus can significantly boost birthrates for IVF.
