Our success rates for treating infertility have consistently proved to be among the highest in the U.K. even allowing for the fact that our Centre accepts all cases and is known to try to help even the most difficult cases. Please keep in mind that your particular success rate may vary slightly because of a variety of individual factors, which may increase or decrease your likelihood of having a baby. As illustrated in the figures below, a woman's age is the most important variable affecting success rates, with the number of pregnancies decreasing sharply after the age of 40.
We are pleased to publish our 2005 Live Birth Success Rates. Please not the age brackets differ for some treatment types. All ages relate to the woman treated.
