Preimplantation Genetic Screening / Comprehensive Chromosomal Screening
For women who are considering pregnancy at a later age, or for women who have experienced repeated miscarriages, our London fertility clinic offers pre-implantation genetic screening (PGS) / comprehensive chromosome screening (CCS). PGS / CCS is an advanced IVF treatment which involves chromosomal screening of embryos prior to replacement in the womb.
As part of this treatment, we’ll take a few cells from each embryo and assess them for chromosomal normality. We do this by checking chromosome number and arrangement. The results of genetic testing are obtained within a few days at our IVF clinic London and the tested embryos are vitrified or flash frozen until they are transferred.
We give patients fertility medications to prepare their womb for replacement of the embryos a month or two later. In PGS or CCS, the genetic material of the embryos is only tested. It is not altered in any way.
At London IVF and Genetics Centre, we offer CCS to carefully selected patients. Often women who are considering pregnancies at a later age, but also, women who have experienced repeated failed IVF treatment or miscarriages. Some had confirmed chromosomal abnormality in previous pregnancy or miscarriage.
