For National Fertility Awareness Week we've published fresh statistics on a range of subjects. Scroll down to find out more.
Birth rate and multiple birth rate (IVF including ICSI)
This is births per embryo transferred by the type of cycle. For example, for the first bar, 30% of embryos transferred under 35 using fresh cycle/own eggs resulted in a birth. The ‘all’ band is an average of all the other bars within each age category.
The reason why the overall births figure for women over 44 appears to rise again is most likely driven by the type of treatment that women over 44 seek (younger women are more likely to be trying treatment with their own eggs, for example, rather than donor eggs), coupled with the influence of different population sizes (for example, the age band 44+ is much bigger than the narrower 43-44).

Twins might seem like a dream come true, but multiple births can seriously harm the health of both mum and babies. At least half of twins are born premature and underweight, which can lead to serious (in some cases, long term) health problems and even death. You’re also far more likely to have an early or late miscarriage if you’re carrying multiple babies.
So, since 2008 the we’ve been working with UK clinics to reduce the multiple births rate. As this graph shows, it’s now down from 26% in 2008, to 16% today, with some clinics even achieving our target of only 10% multiple births. All without any reduction in success rates.
