Success Rates

Honesty is so important to us, especially when it comes to reporting our rates of success. We report clinical pregnancy rates per embryo transfer, rather than positive pregnancy rates alone. Our policy is to report success rates from a longer time period, not just the last year, to prove the strength of our approach. We are proud to say our success rates are consistently above the European average.
