For women intending to undergo IVF treatment using frozen eggs, the younger they are when they are frozen the greater the chance of a successful pregnancy, according to a report by the UK’s independent fertility regulator.
Most IVF treatment cycles use fresh eggs, but a very small number use eggs that have been frozen and thawed. It can, for example, be especially beneficial for cancer patients who decide to freeze their eggs before undergoing chemotherapy.
The report by the Human Fertilisation and Embryology Authority (HFEA) looked at data from UK fertility clinics from 2010 to 2016, and found that the key factor for successful pregnancies is the age at which women freeze their eggs.
