UK approves three-parent fertility treatments and more researchA form of assisted reproductive technology that could make it possible for women with mutations in mitochondrial DNA to give birth to children free of mitochondrial disease has been approved by UK’s House of Commons. A Food and Drug Administration (FDA) committee is considering granting similar approval for use of the technique—known as oocyte modification or three-parent gene therapy—in the United States.
