Frozen Embryo Replacement Cycle (FERC)

In IVF treatment , many eggs are collected and the resulting embryos created. The best embryos are selected for embryo transfer with the number to be transferred predetermined by your consultant.

The remaining embryos are cryopreserved (frozen) if deemed suitable (and both partners agree to this). It is important to note that about 50% of embryos are suitable for freezing and about 70% of those frozen survive once they are thawed.

The replacement (transfer) of frozen embryos can be carried in a "natural" cycle providing the women's menstrual cycle is regular and she is ovulating.

In cases where the cycle is irregular or the woman has difficulties coming up to the clinic or she is not ovulating then we prepare the lining of the womb with hormones.
