PGS Success Rates
At The Centre for Reproductive and Genetic Health, we are able to scan embryos to pick those most likely to result in a healthy, successful pregnancy, before implanting them into the womb. This is done through a microscopic examination of the chromosomes within the embryos; a procedure known as PGS (preimplantation genetic screening).
