At Aria, we aim to perform all embryo transfers at the blastocyst stage on day 5 of embryo development. Overall, in 2021, over 95% of our patients had an embryo transfer on Day 5. All (100%) of our patients embarking frozen transfers had an embryo at the blastocyst stage.
The greatest risk to babies born as a result of fertility treatment is prematurity associated with multiple pregnancy. At Aria, patients receive individualised advice about the recommended number of embryos to transfer based on the quality of their embryos, risk of multiple pregnancy and their personal wishes. Our current multiple birth rate per embryo transferred is 3.1%.
Success rates can be presented in different ways, so it is important to understand what each measure refers to for direct comparison:
- Biochemical pregnancy/Positive pregnancy test: percentage of pregnancies confirmed through a urine test, which can be further confirmed via a b-HCG test. This hormone is key and high values represent an ongoing pregnancy.
- Clinical pregnancy: percentage of pregnancies confirmed after an ultrasound, where the heartbeat can be observed.
- Live birth: percentage of pregnancies resulting in a live birth.
In support with HFEA recommendations, we present births per embryo transferred as it promotes embryo transfer practices that minimises the chances of twins, which carry health risks for the babies and the mother. However, this measure does not incorporate the outcomes of patients who do not reach embryo transfer stage.
The HFEA makes available the results of every licensed clinic in the UK. As a new clinic, Aria does not have HFEA-verified results however you can find national data collected by the HFEA. The individual results of a clinic are of limited value in comparing centres and choosing a fertility clinic. The HFEA provides helpful information to guide patients searching for a fertility clinic that is right for them – follow this link to learn more.
