Simply success rates
When choosing a clinic for your fertility treatment, we understand that success rates are an important part of the decision-making process. At TFP Fertility, we'll provide you with a clear and honest overview of your chances of success.

How our success rates are reported
TFP Simply Fertility is licensed by the Human Fertilisation and Embryology Authority (HFEA), the UK regulator of fertility treatment. All licensed fertility clinics in the UK, including those in Northern Ireland, are required to submit treatment and outcome data to the HFEA, which independently verifies and publishes this information through its Choose a Fertility Clinic service.
The fertility clinic success rates shown below use the two measures selected by the HFEA for clinic comparison and are based on live birth outcomes from treatments using patients’ own eggs.
What this shows
The percentage of patients who had a baby following an egg collection, including all fresh and frozen embryo transfers arising from that collection. If more than one baby is born (for example twins), this is counted as one birth event. Treatments using donor eggs are excluded.

Births per embryo transferred – excluding donor eggs and PGT-A
This chart shows the proportion of embryo transfers that resulted in a live birth for patients treated at TFP Simply Fertility (Chelmsford). Outcomes vary between individuals, and this data reflects overall clinic results rather than an individual’s chance of having a baby.
*This data shows the number of live births per embryo transferred from IVF and ICSI treatment cycles using patients’ own eggs. Results include both fresh and frozen embryo transfers.
