Research presented at a conference has claimed that supplementing egg cells with a specific protein can halve rates of aneuploidy (having an incorrect number of chromosomes).
The research has not yet appeared in a journal but has been the subject of two articles in the Guardian (see here and here).
'If true, the claims… are of great importance to IVF for women with repeated problems of in vitro fertilisation failure and early miscarriage, but perhaps also generally as a means to improve IVF efficiency,' said Professor Robin Lovell-Badge from the Francis Crick Institute, who was not involved in the research. 'However, it is difficult to judge these claims on the rather limited data provided – none of which has been through peer review as yet.'
