A big thank you to all of the staff at the centre for your care and patience during my recent visits

Our IVF success rates

Fertility success rates show the percentage of pregnancies or live births as a result of fertility treatment

London Fertility Centre has poster accepted at scientific conference

LFC ESHRE scientific poster 2014One of our embryologists has had her scientific study accepted for a poster presentation at the European Society of Human Reproduction and Embryology (ESHRE) 2014

 

London Fertility Centre is piloting ways to increase the recovery and survival of vitrified embryos and subsequently improve our clinical pregnancy rate (CPR).

Embryo cryopreservation is now applied widely and is very successful. Vitrification is the most common method used for freezing human gametes and embryos, as it has gained a foothold over the old method of slow freezing because of the higher rates of survival that it provides. Different devices, on which the embryos are loaded, are used clinically for embryo vitrification.

For this reason, the old device, called Cryotip, was replaced in October 2012 by a new device, called Rapid-i. All the Frozen Embryo Replacement (FER) cycles that took place between October 2012 and January 2014 were analysed in order to determine whether there is a significant difference in embryo recovery, survival and CPR.

We demonstrate that our new device is more successful than the old one. Embryo recovery, survival and CPR were higher for embryos vitrified on Rapid-i, in comparison to those vitrified on Cryotip. Statistical analysis showed that this difference is significant for embryo recovery and survival, but not for CPR, yet.

IVF success rates should only be used as a general guide to a clinic’s performance. They can be affected by:

  • the type of patients a clinic treats (e.g. their age, diagnosis, number of previous treatments and length of infertility)
  • the type of treatment a clinic carries out
  • a clinic’s treatment practices

We treat patient with highly complex fertility needs, including women who suffer recurrent miscarriages, people who have already had multiple IVF cycles at other clinics, patients with Hepatitis C and those who have genetic fertility issues.

More about our success rates

We are proud of our success rates and the high standard of care we offer, which has led to the birth of thousands of babies at London Fertility Centre.

It has always been our practice to put you in the driving seat when it comes to your treatment options. Whether your chances are very slim or really quite strong, we believe you should be given the facts, then presented with the options.

Clinical pregnancy rates for other fertility treatments

Clinical pregnancy per embryo transfer, by combined age groups

Type of treatment 2013
IUI with donor sperm (stimulated cycle) 30% (7/23)
IUI with donor sperm (natural cycle) 16% (1/6)
Frozen embryo transfer 30% (19/63)

 

Verified success rates per started treatment cycle and per embryo transferred and national information
are available from the HFEA website.

In our tables, we are giving clinical pregnancy rate and live birth rate per embryo transfer procedure (completed cycle),
as this information is not available on the HFEA website.

Please note that success rates have limitations as the basis for comparison and personal choice.
