Detailed breakdown of patients treated by this clinic
The types of patients a clinic treats affects the clinic's live birth rates. It
can therefore be misleading to directly compare the success rates of different clinics
as they differ in the types of patients they treat. The vast majority of clinics
perform around the national average.
Please be aware that the data on diagnoses and reasons for treatment, as well as
on length of infertility is submitted by clinics but not currently verified by the
HFEA.

Details cycles and cancellations
What data do you want to look at?
Use the drop down menus for each category below (age group, year, treatment cycles,
and source of embryos) to select the data you wish to view. The data in the table
below will change according to what categories you have selected.
Please be aware that the more criteria you select the fewer treatment cycles the
data will be based on. The smaller the number of treatment cycles the less reliable

More about how we collect and publish data
Back to top
The information that we publish on our website is a snap shot of data provided to
us by licensed centres at a particular time. This information may be subject to
change as individual centres notify us of amendments. Before publication, we perform
a preliminary validation process on the data, and ask centres to confirm its accuracy,
for which they remain responsible.
Hints and tips
Patient had not produced enough eggs to collect after taking fertility drugs
In most IVF and ICSI cycles women take fertility hormones to boost the number of
eggs they produce so that more eggs can be fertilised and the clinic has a greater
choice of embryos to use in treatment. Occasionally a woman does not produce enough
eggs after taking the hormones to go ahead with an egg collection.
Patient had an adverse reaction to fertility drugs – unsafe to continue cycle
In most IVF and ICSI cycles women take fertility hormones to boost the number of
eggs they produce so that more eggs can be fertilised and the clinic has a greater
choice of embryos to use in treatment. Occasionally women can have an over-reaction
to these fertility drugs, which may lead to a potentially dangerous condition called
ovarian hyper-stimulation syndrome (OHSS). For the safety of the patient, a clinic
will not continue a treatment cycle if there is a risk of this happening.
Other
There are various other reasons why a treatment cycle may be cancelled. For example
if the patient is unwell or if they decide they do not want to continue with their
treatment.
Embryos did not develop normally
Sometimes after eggs are fertilised with sperm, the embryos do not develop normally.
If there are no good quality embryos available to transfer, the clinic will have
to cancel the patient’s cycle.
Embryos tested positive for a genetic test
Some patients undergoing IVF or ICSI will also have their embryos genetically tested
using preimplantation genetic diagnosis (PGD) or preimplantation genetic screening
(PGS) before deciding whether to transfer embryos. For example if there is a risk
of passing on a heritable condition to any future child, such as muscular dystrophy.
Sometimes the cycle will have to be cancelled if there are no embryos available
that are free from the genetic condition.
Proportion of single embryo transfers (elective)
Elective single embryo transfer is where a woman has several embryos available to
transfer and decides to transfer just one. Single embryo transfer is encouraged
in good prognosis patients to minimise the risks associated with having a multiple
pregnancy (twins and triplets).
Proportion of all embryo transfers that were blastocysts
Most embryo transfers take place after the embryos have been cultured in the laboratory
for 2-3 days after fertilisation. Some clinics now culture embryos for 5 or more
days, until the embryo reaches the blastocyst stage, before transferring them.
Pregnancies and live births per treatment cycle
This shows how many women became pregnant and had a live birth out of those who
had a treatment cycle.
Pregnancies and live births per embryo transferred
This shows the likelihood of each embryo transferred resulting in a pregnancy and
live birth. It takes into account how many embryos clinics transfer in their cycles
(eg, one, two or very occasionally three embryos). The success rates appear lower
than for live birth per cycle because clinics often transfer two embryos in a cycle.
Proportion of single embryo transfers (non elective)
Non elective single embryo transfer is where a woman has one embryo transferred
because this is the only embryo she has available. This may be because only one
embryo was created or because other embryos were created but were not high enough
quality to transfer.
Miscarriages per cycle
The miscarriage data we show refers to any cycles where a woman miscarries and has
no live birth. It does not include twin (or triplet) pregnancies where the woman
miscarries one foetus but the remaining child is born.
