We're redesigning our website - we're keen for you to try it so we can hear your views on how it can be improved ahead of the official launch. Head on over to the HFEA BETA to see how it is shaping up.

Embryo testing

What is pre-implantation genetic testing?

Embryos created through in vitro fertilisation (IVF) or intra-cytoplasmic sperm injection (ICSI) can be tested for certain inherited conditions or abnormalities before they are transferred to the womb. This helps to ensure that only unaffected embryos are put in the womb during treatment.

Conventional pre-natal tests for genetic diseases cannot be carried out until the 11th week of pregnancy. Testing embryos before they are implanted can help avoid miscarriage or having to make a difficult decision about whether to end an existing pregnancy.

If you are considering genetic testing, you should talk to your GP to go through the options available. Your GP will also refer you to see a genetic specialist at your local hospital or fertility clinic.

There are only a small number of clinics in the UK that offer embryo testing – you can find the one nearest you using the Choose a Fertility Clinic search function and refining by embryo testing facilities.
