Egg collection and fertilisation
Egg collection is performed 37 hours after the late evening injection. The eggs are recovered using ultrasound through the vagina. A fine needle is passed through the ultrasound probe directly into the ovarian follicles (the structures in the ovary which contain the eggs) and the eggs are gently aspirated. This procedure is performed under sedation administered by an anaesthetist. You will not be aware of the procedure although the sedation is not as strong as a general anaesthetic. Typically, the egg collection lasts ten to fifteen minutes. It is usually possible to collect eggs from between 80-100% of the larger follicles. The eggs are inspected in the laboratory for a preliminary idea of their maturity. You would remain in the clinic for approximately an hour after the procedure. You would then able to return home but another adult should accompany you. We advise you to take the whole day off work.
