Drug-Free IVF Could Be Cheaper and Faster Way to Get Pregnant

August 23, 2016

(New Scientist) – An alternative is to remove a woman’s eggs while they are still immature and mature them in the lab before fertilising them. But this technique – called in-vitro maturation (IVM) – is less successful, with a success rate around half that of IVF. As of last year, only around 400 babies worldwide had been born using this method. Now Ledger’s colleague, Robert Gilchrist, has found a way to increase the number of embryos produced by IVM by 50 per cent. He did this by combining two growth factors that stimulate egg maturation into a single compound for use in IVM.
