Once your eggs have been collected, they are placed into a special culture medium and then mixed with your partner’s sperm, before being incubated in the laboratory in a controlled environment for 16-20 hours. They are then checked to see if any have fertilised. Those that have been fertilised (now called embryos) are allowed to grow for up to a further five days before being checked again.
After this final check, either Dr Ndukwe or your fertility nurse will arrange a time to give you the results and, hopefully, to fix a time to transfer the embryo or embryos back into your womb. Each developed embryo will be reviewed by an embryolgist under a electronic microscope in order to allow us to determine which would be the best ones to transfer. The law allows a maximum of two embryos to be transferred for women who are under 40 years old and a maximum of three for anyone who is over 40.
