Oocyte cryopreservation

Oocyte cryopreservation is when doctors freeze tiny eggs called oocytes so that they can be used later to make a baby. Here's how it works:

First, doctors give the woman hormones to make her ovaries make lots of eggs. Then, they carefully take out the eggs using a special needle. These eggs are put into small tubes and frozen very quickly.

When the woman is ready to have a baby, the doctors will unfreeze the eggs and combine them with sperm from a man. This creates an embryo that can be put into the woman's uterus, where it will grow into a baby.

Cryopreservation is helpful for women who want to have a baby in the future, but aren't ready yet. It can also be helpful for women who have medical conditions that might make it hard for them to have a baby, like cancer treatment.

By freezing their oocytes, women can keep their chances of having a baby alive for many years to come.
