Egg freezing for age-related fertility is becoming more common, and a short article in CMAJ (Canadian Medical Association Journal) provides points on the topic

1. Elective egg freezing is a way to help patients increase their chance of pregnancy at a later age 

2. Patients aged 35 or younger with normal ovarian reserve have the best chance of success, although future live birth is not guaranteed 

3. The treatment process usually takes 10-14 days 

4. Fees for this treatment may not be covered by health insurance 

5. Frozen eggs do not expire, but many clinics have age limits after which they will not proceed with transfer of embryos created from the frozen eggs.
