Many people find that looking at clinic statistics can feel reassuring, while others may find numbers a little daunting. Wherever you are emotionally, this page offers clear, calm information about the treatments we carried out in 2025.

Across the year, we performed 661 embryo transfers. Most were carried out at the blastocyst stage (98.6%, and almost all involved transferring a single embryo (93%). This approach helps keep treatment as safe as possible and supports patients who want to minimise the chance of a multiple pregnancy.
The types of transfers performed varied. More than half were frozen embryo transfers following preimplantation genetic testing using own eggs (PGT, 57%), while others involved frozen untested embryos (28%), fresh transfers (6.5%), or donor egg treatment (8.5%). Each pathway reflects different needs, circumstances, and preferences for each individual or couple.
Our aim in sharing these figures is not to compare journeys or set expectations, but to offer transparency about the care we provide. If you’re exploring treatment options, these numbers can be a helpful starting point for conversations with your clinical team about what feels appropriate for you.
The table below shows the biochemical and clinical pregnancy rates per transfer for embryos that were tested with PGT in 2025. Biochemical pregnancy rate is calculated using the number of cycles with a positive pregnancy test divided by the number of transfer cycles, shown as a percentage. Clinical pregnancy is confirmed by the observation of foetal heartbeat on an ultrasound scan.
PGT does not ‘improve’ an embryo. Rather, it helps identify the embryo most likely to implant, most likely to lead to a healthy pregnancy, and least likely to result in miscarriage. By reducing uncertainty, PGT can shorten the time to pregnancy and reduce the emotional and physical burden of repeated transfers. Its value is most evident when comparing outcomes between tested and untested frozen embryo transfers. The table below shows the clinical pregnancy rates per transfer for embryos that were tested versus untested in 2025.
Fresh transfers represented a small minority (6.5%) of our cycles in 2025. While fresh transfer remains appropriate in selected cases, the predominance of frozen cycles reflects the advantages of controlled endometrial preparation, improved scheduling, and the opportunity to incorporate PGT where indicated.
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.
