Here you can find out about our IVF/ICSI rates for births per embryo transferred, births per egg collection and multiple births to provide an overall view of our performance.
National rate: It may be tempting to obsess over success rates, but the most important thing to focus on is whether the a fertility clinic’s results are consistent with the national average.
Reliability range: The reliability range shows how confident we are that we will repeat our success rate in the future – the narrower the range, the more confident we can be.
This rate shows the number of births (counted as a single birth event ie. twin births count as one live birth event) divided by the total number of embryos transferred.
We present births per embryo transferred as it promotes embryo transfer practices that minimises the chances of twins, which carry health risks for the babies and the mother. However, this measure does not incorporate the outcomes of patients who do not reach embryo transfer stage.

This rate shows the number of births (counted as a single birth event ie. twin births count as one live birth event) divided by the number of egg collections. This figure is calculated by selecting qualifying egg collections over a 12 month period and following their usage over a maximum of 24 months.
This rate shows the chance of success from all the fresh and frozen embryo transfers within two years of one egg collection. Whilst births per embryo gives you an indication of success rates for just one embryo transfer, births per egg collection gives an overall picture of success rates for a full course of treatment (which can include one fresh and a number of frozen transfers).
Filter by age range
This rate shows the number of multiple birth events (counted as a single multiple birth event ie. twin births, triplet births, quad births all count as one multiple birth) divided by the total number of birth events (counted as a single birth event ie. singleton, twin birth, triplet birth, quad births all count as one birth event)
For some people, having twins may seem like a wonderful thing, but multiple pregnancies are less safe for both mother and babies. The HFEA target for all clinics is to have a multiple birth rate of 10% or lower.
