Your egg, sperm and embryo storage options

Freezing and storing embryos
During fertility treatment there are normally a number of unused embryos remaining. Some people choose to freeze the good quality unused embryos for use in later treatment cycles or for donation.


Freezing and storing eggs
To help boost egg production, fertility drugs are used to stimulate the ovaries to produce more eggs than usual. The developing eggs are monitored and when they are mature they are carefully collected under sedation or general anaesthetic. To freeze the eggs, they are placed in storage in liquid nitrogen.


Freezing and storing sperm
Sperm can be frozen for future use either in artificial insemination or other fertility treatments, or be donated. Donated sperm has to be stored for six months before it can be used in treatment in order to screen the donor for infections.
