IVF mix-up causes wrong sperm to fertilise eggs of 26 women
A Dutch IVF laboratory may have mistakenly fertilised up to 26 women's eggs by sperm from an unintended father. The 26 couples affected by the goof-up have been informed about the mistake by the institution. In-vitro fertilisation involves collecting mature eggs from a woman's ovaries before fertilising them by sperm in a laboratory.
