NICE guidelines indicate that you have a higher chance of getting pregnant with IVF if your BMI (Body Mass Index) is between 19 and 30.
You can have treatment at Bourn Hall with a BMI between 19 and 35, but to be eligible for NHS funded treatment your BMI will need to be 30 or under. Having a BMI of more than 30 does have a significant negative effect on IVF pregnancy success rates and your Consultant will discuss options available to you if your BMI is over 30 and you are looking to fund your own treatment.
Although IVF success rates are most favourable in women with lower BMIs, there are ways to improve the success rates in patients with BMIs of 25-30. This includes using the antagonist protocol instead of the longdown regulation protocol, which heralds better results in women with a higher BMI. Find out more about improving success rates for women with a BMI between 25-30.
