Births per embryo transferred
National Average – Under 38 years – 31% / 38 & Over – 11% / All – 21%
We present births per embryo transferred (rather than births per cycle) because fertility professionals say it’s the best measure of a clinic’s success and it allows you to make a fair comparison between clinics. Remember, it can’t tell you your individual chance of success (only your doctor can do that); but it does give a fair overall view of their performance.
Births per egg collection
National Average – Under 38 years- 38% / 38 & Over – 16% / All – 29%
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).
Multiple birth rates
National Average – Under 38 years- 14% / 38 & Over – 11% / All – 13%
For some people, having twins may seem like a wonderful thing, but multiple pregnancies are much less safe for both mother and babies. That’s why we’ve set a target for all clinics to have a multiple birth rate of 10% or lower – see how well they’re performing below.
IUI Pregnancy Rates
These are the pregnancy rate per IUI treatment using partner sperm.
Donor Insemination Birth Rates
These are the birth rate per donor insemination treatment.
