What are my chances of achieving a pregnancy from treatment?

One of the most frequent questions we are asked by anyone considering assisted conception is ‘what are my chances of achieving a pregnancy with IVF?´ This is often a difficult question to answer as your chances of becoming pregnant will depend on a number of factors, such as how old you are, what kind of fertility problem you have and which type of treatment you need. Each individual will be slightly different and couples may have a combination of factors affecting their probability of conceiving making it difficult to provide an exact figure for any individual.

IVF Clinics may express their pregnancy rates in different ways and this can be confusing. Some clinics will count all positive pregnancy tests in their figures. However, some pregnancies may miscarry at a very early stage or be ectopic pregnancies. Other clinics may present pregnancy rates based on results per cycle started, per egg collection or embryo transfer. We believe that the best way to express pregnancy rates is by expressing the number of treatment cycles that actually result in a live birth as a percentage of all the cycles started. This is the method recommended by the HFEA (Human Fertilisation and Embryology Authority).

On this page we have given the figure for our live birth rate per cycle started. This means the chance of achieving a live birth from each cycle that you start. This also therefore includes any cycles that have been started and then cancelled.

The more recent figures can only be expressed as the chance of achieving a clinical pregnancy. This means when a baby´s heartbeat is seen on a scan. The majority of treatment cycles resulting in a clinical pregnancy will result in the birth of a baby. The live birth figures will be treatments that were started two years previous (so that the data can be collected of the live births by the HFEA). Results are updated every 6 months from the HFEA.
