Controversial IVF Technique Produces a Baby Girl–And for Some, That’s a Problem

January 20, 2017

(CNN) – In 2015, the United Kingdom approved pronuclear transfer, but only for women suffering mitochondrial disease. The technique replaces defective mitochondria in a mother’s egg with healthy donor mitochrondria as a way of preventing mitochondrial disease from being passed on to a child. The reason this experimental method is a cause for concern — and was vigorously debated in the UK before approval — is the genetic modifications produced in a girl baby could be passed onto her children, according to Lori P. Knowles, adjunct assistant professor at the University of Alberta School of Public Health.
