ICSI Treatment Stage 3

The scan will be checking the response to the FSH injections. The follicles will be counted and measured. When the follicles are a Stimulated Ovary certain size approximately 18mm, this indicates that there may be a mature egg present (unfortunately not all follicles will contain eggs). At this stage, depending on the number and size of the follicles will determine when the egg collection will be scheduled. If the ovaries have responded well to the FSH injections then another injection called HCG or Human Chorionic Gonadotrophin will be advised to be administered. This injection helps to mature the eggs present and to release the eggs in the follicles for the egg collection. It is advised that this injection is taken approximately 36 hours prior to the scheduled procedure. Normally after this injection all other drugs are stopped.
