Considering PGT

Preimplantation genetic testing (PGT) is IVF with testing of the embryos before one is transferred. Couples usually consider it when one or both of them carry a known genetic condition or a chromosome rearrangement, so that an embryo without it can be chosen.

Answer four questions and the guide sets out which type of PGT fits, how many embryos to expect, each step from the first review to pregnancy, and the results an embryo can get. Nothing you enter is stored.

You can see Dr Tristan Hardy whether or not you already have an IVF specialist, wherever you are being treated. Ask your GP specialist or IVF specialist for a referral addressed to him, or talk to us first.
