Details.
Egg freezing, also known as egg vitrification or cryopreservation, includes ovarian stimulation with injections, monitoring visits with ultrasound scans and occasional blood tests, an egg collection procedure under anaesthetic, and rapid freezing and storage of mature eggs using vitrification. The process is suitable for medical fertility preservation, including before cancer treatment or procedures that may cause infertility, and for non-medical social reasons. A cycle usually takes 2 to 3 weeks, with monitoring visits typically lasting 20 to 30 minutes and the egg collection procedure usually lasting 20 to 30 minutes. Eggs can be stored for up to 55 years, with consent renewed every ten years.
