Guy’s hospital and Sheffield clinic may have used faulty freezing solution that could damage eggs and embryos

Faulty egg-freezing products which affected more than 100 women at a London fertility clinic have also affected a fertility clinic in Sheffield, the fertility regulator has said.

The HFEA confirmed that the issue was limited to Guy’s and St Thomas’ Assisted Conception Unit in London, and Jessop Fertility in Sheffield.
