Highest IVF/ICSI live birth rate in London
We are very pleased to announce that we have the highest IVF/ICSI live birth rate in London per embryo transferred (fresh embryos patients’ eggs all ages) according to the latest data published by The Human Fertilisation and Embryology Authority (HFEA). Click here.
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).
