HFEA (Human Fertilisation and Embryology Authority) is the UK's independent regulator that oversees the use of gametes and embryos in fertility treatment and research. It also licenses fertility clinics and centres carrying out in vitro fertilisation (IVF). The authority presents success rates for every licensed clinic. These rates show the number of treatments carried out by the clinic and the number of pregnancies or live births that were born as a result.
