The Human Fertilisation & Embryology Authority (or, HFEA, for short) is the UK’s independent regulator for fertility treatment (as well as for fertility research).
The HFEA ensures that all UK fertility clinics comply with the law. As well as making sure clinics meet the required standards of quality and care, the HFEA also collects treatment outcome data from all registered fertility clinics in the UK and makes it available on its website (or raw data can be downloaded).
The HFEA gathers data from fertility clinics about all the treatments they provide. The HFEA, as part of its role, also inspects each clinic at least every two years to check that their standards are being maintained.
