Regeneration of oocytes from discarded genetic material: will this double IVF success rates?

28 November 2016 - by Dr Philip Lewis and Professor Daniel Brison

Reassurance for mothers over mosaic aneuploidy in CVS

03 May 2016 - by Professor Magdalena Zernicka-Goetz

Although our recent findings on the fate of aneuploid cells in mosaic embryos have indeed been somewhat misrepresented in the press, our findings may still constitute a strand of hope for mothers who have had early test results showing mosaic aneuploidy... [Read More]
