Mistakes found in one in 100 IVF cases
For every 100 women who undergo IVF, one will suffer an "adverse incident", new figures show.
On average, there are 500 to 600 mistakes made in every 60,000 cycles of fertility treatment, according to the Human Fertilisation and Embryology Authority (HFEA).
Its latest report suggests that from the start of 2010 to the end of 2012 there were 1,679 adverse incidents in UK fertility clinics.
The authority, which licenses fertility clinics and centres carrying out in vitro fertilisation (IVF), said there were three of the most serious adverse events, known as grade A mistakes, 714 grade B incidents and 815 grade C errors during this time frame.
One of the most serious mistakes reported was a family receiving the wrong sperm. The couple were supposed to be given sperm from a specific donor – so their child would have the same genes as their sibling – but they were given a different man's sperm.
Another incident involved dishes with the embryos of 11 patients becoming contaminated with "cellular debris that may have contained sperm," the report states.
