The number of embryos to transfer are based on the regulations in the UK, a patients age and embryo quality.  If you are young and it is your first treatment we would strongly advise you to have a single embryo transferred.  If you have had a previous cycle and are under 40 you may be able to have 2 embryos transferred.  It is not possible to transfer more than 2 embryos unless you are over 40 and then we would only ever transfer 3 in exceptional circumstances. If you please need any further information please call our New Patient Team on 0161 300 2737.
