The UK government has issued a stern warning to fertility clinics, urging them to stop offering ineffective and unproven treatments to couples trying to conceive. The Human Fertilisation and Embryology Authority (HFEA), UK’s fertility regulator, has raised concerns over the increasing number of fertility clinics that are promoting add-on treatments, which have no proven benefits, to their patients. This comes after a report indicated that only 1% of add-on treatments offered by fertility clinics in the UK have strong evidence to support their effectiveness. The HFEA has stressed that these add-on treatments are not only costly but can also cause potential harm to the patients. They have urged fertility clinics to be transparent with patients about the effectiveness and risks associated with these treatments.
