There were three "grade A" or major mistakes made by fertility clinics over a two year period, the industry regulator said.
HFEA discovered over a two year period starting in 2010 fertility specialists:
- Gave one family the wrong sperm.
- Another incident involved dishes with the embryos of 11 patients becoming contaminated with "cellular debris that may have contained sperm".
- The final grade A error occurred when a member of staff destroyed frozen sperm from storage while it was still within its consent period.
