HFEA

According to data from the HFEA, egg donation has remained largely the same since the 2011 compensation rise but demand for eggs has increased.

There were more than 4,000 egg freezing procedures in the UK in 2021, compared with nearly 400 in 2011, according to HFEA.

It could be as low as 5% for people in their 40s, according to HFEA.

She added: "Current patients may continue to be treated at the unit despite the licence suspension by the HFEA, and our very dedicated staff are keen to support patients in whatever way they can."

Julia Chain, who chairs HFEA, said she was "concerned" about people having to import sperm because using "online donors can be extremely risky".
