We’ll only ask you to donate if you have a similar tissue type to someone in desperate need of a transplant. Most people on our register never donate.

Once you are on the register you have a 1 in 800 chance of being asked to donate in the next five years. 

However, it is worth knowing that your chance of being chosen to donate depends on your age and sex. A young man aged 16–30 has a 1 in 200 chance of being chosen to donate in the next five years.
