How many embryos to transfer?
The Human Fertilisation and Embryology Authority now only permits the transfer of two embryos except in exceptional clinical circumstances. This is to reduce the risk of a multiple pregnancy. The live birth success rate for a two embryo transfer is not significantly different to that of a three embryo transfer.
Luteal Phase Support
Luteal Phase Support is started two days after egg collection regardless of day of embryo transfer. This is given in the form of Cyclogest pessaries or Gestone injections.
Embryos may be frozen at any stage but only Grade 1 and 2 embryos are classed as suitable for freezing. Embryos are graded on a scale of 1-4 with 1 being the best. Around two thirds of embryos survive the freeze/thaw process.
Frozen embryo replacement can be carried out in a cycle supported by HRT or in a "natural" cycle.
