Frozen Embryo Transfer Cycles

Frozen treatment cycles – Clinical Pregnancy Results 2018  (full calendar year)

 

Our 2018 results for frozen embryo transfer cycles have not yet been validated by the HFEA, but we like to keep you informed of our current success rates. In 2018, 95 frozen embryo transfer (FET) cycles using the patients’ own eggs resulted in an embryo transfer. The results have been broken down into age categories.

The following table only includes patients using their own eggs. No surrogacy cases are included.

Age Clinical pregnancy events per treatment cycle started Clinical pregnancy events per embryo transfer Foetal hearts per embryo transferred.
All ages 40/98, 40.8% 40/95, 42.1% 41/103, 39.8%, 39 singletons, 1 twin.
<35 28/59, 47.5% 28/59, 47.5% 28/63, 44.4%, 28 singletons.

Frozen treatment cycles – Live Birth Results 2017  (full calendar year)

In 2017, 118 frozen embryo treatment cycles using the patients’ own eggs resulted in an embryo transfer. As this is the most recent data the results have not yet been validated by the HFEA, but we like to keep you informed of our current success rates. The following table only includes patients using their own eggs. No surrogacy cases are included.

 

Age Live birth events per embryo transfer Live births per embryo transferred
All ages 45/118, 38.1% 46/144, 31.9%, 44 singletons, 1 twin.

Success Rates for patients using donor eggs in frozen treatment cycles

Some patients who create embryos with donor eggs may have embryos frozen and used in a frozen embryo transfer cycle. Clinical pregnancy rates for 2016-2018 and live birth rates for 2015-2017 are shown below. Please note these results are for a 3-year period due to low patient numbers.

Donor eggs Per embryo transfer Per embryo transferred
2016-2018 Clinical pregnancy 4/11, 36.4% 4/14, 28.6%
2015-2017 Live birth 2/11, 18.2% 2/17, 11.8%
