Success rates play a major part in helping many patients choose which clinic to attend.  We strongly encourage all patients to review success rates before choosing their clinic.  The Human Fertilisation and Embryology Authority (HFEA) publish success rates for every licensed clinic in the UK, usually every six months of the year. They show the number of treatments cycles carried out in a particular year, they also show the number of clinical pregnancies and live births.

It is important to recognise that success rates have their limitations and a number of things can affect your success rates, including

  • the reason for infertility
  • the type of treatments available at the clinic
  • the expertise of the clinic staff
  • the clinic’s treatment practices

At Nurture Fertility we understand that sometimes the way in which clinics present their success rates can be confusing especially if you are at the beginning of your IVF journey. We will always provide you with the very latest results. The table below shows the latest HFEA verified data for both clinical pregnancy rates and Live birth rates.


Clinical Pregnancy (CP): An ultrasound scan has successfully found at least one foetal heartbeat. This is at around 6 weeks of pregnancy.

Treatment Cycle: A treatment cycle starts when a woman begins taking fertility drugs to stimulate egg production.

Fresh Transfer: The eggs collected are mixed with fresh sperm to produce embryos. Embryos are then incubated in the laboratory for up to five days and then the best embryo(s) are transferred back to the patient.

Frozen Embryo Transfer: After the eggs and sperm are mixed to produce embryos, embryos not selected for a fresh transfer can be frozen for future use. The embryos are thawed and transferred to the patient when the patient is ready for further treatment.

Per cycle started: Number of treatment cycles that have resulted in a clinical pregnancy or live birth shown as a percentage. This will also include any cycles which may have been cancelled before the egg collection or embryo transfer stage.

Per embryo transferred: Number of embryos transferred resulting in a pregnancy or live birth shown as a percentage. It takes into account how many embryos have been transferred in a cycle. These success rates can appear lower than ‘per cycle’ because two embryos can be transferred in some cycles.

Success rates play a major part in helping many patients choose which clinic to attend.  We strongly encourage all patients to review success rates before choosing their clinic.
