Success Rates

CRGH consistently delivers some of the highest success rates in the UK, across multiple age groups, and for a range of treatment options. We continue to pioneer new treatments, and support an active research programme that drives innovation and clinical excellence.

Our latest live birth success rates for 2019, and pregnancy rates for 2020 are published below.

You can find national data on fertility treatment 2019 trends and figures on the HFEA website.

PGS Success Rates

At The Centre for Reproductive and Genetic Health, we are able to scan embryos to pick those most likely to result in a healthy, successful pregnancy, before implanting them into the womb. This is done through a microscopic examination of the chromosomes within the embryos; a procedure known as PGS (preimplantation genetic screening).
