Egg collection

General anaesthetic is recommended. Ultrasound views are used to guide the needle through the side of the vaginal wall into the ovarian follicles. This is a day-case procedure, which takes approximately 30 minutes. You should be well enough to go home approximately 2-4 hours after egg collection.

How many eggs are needed?

To optimise the success of each cycle, the following figures need to be considered:

• 80% of follicles will contain an egg
• 80% of eggs collected will be mature
• 60-70% of the mature eggs will fertilise
• 90-95% of the fertilised eggs will cleave and form embryos
