Cryopreservation is used for the process of preserving fertility by freezing eggs, sperm and/or embryos to sub-zero temperatures for later use.

Since fertility starts to decline once a woman reaches a certain age, an optimal time for a woman to consider freezing her eggs to use for a later pregnancy would be in her late 20’s and/or early 30’s.

It is at that time that women will generally have a higher ovarian reserve (the number of eggs in her ovaries) and healthier quality eggs.

Cryopreservation is a relatively safe, advanced procedure and can often lead to a successful pregnancy later.

Research has shown that the process of freezing and thawing embryos does not harm babies and children born from frozen embryos.  It is as safe as children born from “fresh” embryos.
