Depending on the egg bank or the clinic the cost of oocytes from the donor varies. European egg banks offer oocytes from EUR350 per egg/oocyte. You will need, on average, minimum 6 – 8 oocytes. In the USA, where the access to egg donors is open – there are many donors available, the prices are higher and range from $8,000 to even $20,000 for 6-12 oocytes.
