Blastocyst Culture

If you are fortunate and have a number of high quality embryos, one option is to allow these embryos to develop for five days outside the body, to what is termed the ‘blastocyst stage’.

We may suggest you consider blastocyst culture if you have many good embryos, as the chances of becoming pregnant with this treatment within one cycle are much higher. Having only one blastocyst put into the womb reduces the risk of having twins.

Couples who have had a previous multiple pregnancy, or who are at high risk of a multiple pregnancy will be advised to have a single blastocyst replaced.
