PGS / CCS
For women who are considering pregnancy at a later age, or for women who have experienced repeated miscarriages, we offer pre-implantation genetic screening (PGS) / comprehensive chromosome screening (CCS). PGS / CSS is an advanced assisted conception method which involves genetic 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 genetic normality. We do this by checking chromosome number and arrangement. The results of genetic testing are obtained in few days 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 miscarriages. Some had confirmed chromosomal abnormality in previous pregnancy or miscarriage.
