The type of patients a clinic treats affects the clinic’s live birth rates. It may
therefore be misleading to directly compare the success rates of different clinics
as they differ in the types of patients they treat. The majority of clinics perform
around the national average.

Live births per embryo transferred
in the year ending 2nd quarter 2011
This shows the likelihood of each embryo transferred resulting in a live
birth. It takes into account how many embryos were transferred in a cycle. It presents
how many women had a live birth out of the total number of embryos transferred across
all cycles. The success rates appear lower than for live birth per cycle started
because clinics often transfer two embryos in a cycle.

Proportion of single births in the year ending 2nd quarter 2011
The single biggest risk of fertility treatment is multiple pregnancy. The birth
of a single, healthy baby is the safest outcome of fertility treatment.

data
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
Donor cycles
We do not show success rates for cycles using embryos from donor eggs by different
age categories. This is because all egg donors are aged 35 or under.
Live births per treatment cycles
This shows how many women actually had a live birth out of all the women who began
a treatment cycle in this year. A treatment cycle starts when a woman begins taking
fertility drugs to stimulate her egg production.
Live births per treatment cycles
This shows how many women actually had a live birth out of all the women who had
a frozen embryo transfer in this year.
Pregnancies per treatment cycles
This shows how many women actually became pregnant out of all the women who began
a treatment cycle in this year.
Live births per treatment cycles
This shows how many women actually had a live birth out of all the women who had
an DI treatment cycle in this year.
Live births per embryo transferred
This shows how many live births there actually were out of the total number of embryos
transferred across all cycles in this year. It takes into account how many embryos
clinics transfer in their cycles (eg, one, two or very occasionally three embryos).
Proportion of triplets born out of all live births
Any higher order multiples (eg, quads) will also be included in this column.
Proportion of triplet pregnancies out of all pregnancies
Any higher order multiple pregnancies (eg, quads) will also be included in this
column.
Proportion of triplets born out of all live births
Any higher order multiples (eg, quads) will also be included in this column.
HFEA targets for single births
The HFEA introduced a policy in January 2009 to minimise the proportion of multiple births following IVF and ICSI treatment. The policy promotes the birth of a single baby as the safest outcome of fertility treatment.
The HFEA has set progressively higher targets over recent years. From January 2009 to March 2010 the target for single births was 76% (ie a maximum of 24% multiple births). From April 2010 to March 2011 the target was 80%. From April 2011 to September 2012 the target was 85% and from October 2012 onwards the target is 90%.
The clinic data we present on Choose a Fertility Clinic relate to treatments which took place before the current 90% target. The target displayed is the most appropriate for comparison with the data in the tables.
