Egg donors go through a phase of ovarian stimulation so that their ovaries produce large numbers of eggs, as opposed to what happens naturally. To do this, egg donors are administered hormone medication and will have to visit the clinic several times for ultrasound scans.
Thanks to these ultrasound scans it will be possible to evaluate the growth of the ovarian follicles. When the follicles reach 16-18 mm, the ovarian puncture will be scheduled. This is a short procedure performed under anaesthesia and under ultrasound guidance to retrieve the eggs.
