Our Assisted Conception Unit (ACU) is proud of our history of offering both IVF and PGD. Over 1,000 babies have been born following PGD at Guy’s Hospital.
Success rates are published by the Human Fertilisation and Embryology Authority (HFEA). Overall, around one in three (33%) PGD cycles will result in a pregnancy which progresses to term. If there are healthy embryos created, this rises to one in two (50%) per embryo transferred. In other words, each embryo has a one in two (50%) chance of resulting in a pregnancy.
More detail about our success at each step of the PGD process is below.
