New research suggests that if you want to find out about outcomes from fertility treatment at a particular clinic, the best place to go is not the clinic’s own website. Researchers from Manchester University discovered that fertility clinics use a variety of different ways to present their data which makes it very difficult for anyone trying to compare one clinic with another. They found that clinic websites often use league tables which they construct themselves using their own parameters to compare clinics in their area and that these are “invariably constructed so that the comparison was favourable to the reporting clinic.”
If you do want to look at outcomes, it is worth bearing in mind that most clinics have broadly similar success rates and that relatively small percentage differences can be pretty meaningless and may have more to do with the patients being treated at any given time than anything else. The HFEA publishes outcomes broken down by age and this is by far the best place to go for information if you want to look at treatment outcomes as the figures are collected and collated the same way for all clinics across the UK
