Scientists claim to have “rejuvenated” human eggs for the first time in an advance that they predict could revolutionise IVF success rates for older women.
The groundbreaking research suggests that an age-related defect that causes genetic errors in embryos could be reversed by supplementing eggs with a crucial protein. When eggs donated by fertility patients were given microinjections of the protein, they were almost half as likely to show the defect compared with untreated eggs.
