Clinical success rates
There are various ways to measure the success of fertility treatment. For example you can measure it on how likely it is that each embryo transferred will lead to a live birth, alternatively by how likely a cycle of treatment will lead to a live birth.
Although it is tempting to think that you would like twins, multiple pregnancies are the biggest risk to mother and child from IVF/ICSI. We therefore aim to have a high proportion of single babies compared to twins or triplets.
A clinical pregnancy is when a foetal heartbeat has been detected. It is not based just on a positive pregnancy test
Clinical pregnancy rates
The table below shows clinical pregnancy rates from IVF and ICSI treatments at BFC for the period 1 January 2016 to 31 December 2016:
|Patient Age||Under 35||35-37||38-39||40-42||43-44|
|Per fresh embryo transfer||44.3%||28.3%||22.8%||25.0%||0.0%|
|Number of patients treated||152||92||57||52||11|
|Per frozen embryo transfer||45.1%||33.8%||45.9%||24.1%||22.2%|
|Number of patients treated||113||65||37||29||9|
The chances of a pregnancy are different for each person and affected by a number of factors such as age and cause of infertility. We do not select patients based on the likelihood of achieving pregnancy. We believe everyone should be given the opportunity of creating a family even if they have a low possibility of success. We will always be honest about an individual’s chances.
Please feel free to discuss your individual circumstances with a member of the team.
Aberdeen University have created a calculator to help predict your chances of a successful outcome, using 10 years of data from all patients who underwent IVF in the UK.
The figures below show live birth rates at Bath Fertility Centre and nationally for the period 1 July 2013 to 30 June 2014 as verified and published by the HFEA on their website www.hfea.gov.uk.
HFEA analyse data from all UK clinics and they classify our success rates as consistent with national averages: “If a clinic’s success rate is consistent with the national average, there is no statistical difference between the clinic and the national average. Any small difference between the clinic and the national average may just be down to chance.”
Per cycle started
Per embryo transferred
Further treatment cycles will increase your chances of achieving a successful pregnancy.
