Cancer boy's testicular tissue frozen in a UK first
A nine-year-old boy with a brain tumour has become the first in the UK to have testicular tissue frozen with the hope he can have children later in life.
Nathan Crawford has had radiotherapy and chemotherapy to shrink his tumour, but the treatment could render him infertile.
In a new procedure, surgeons at the John Radcliffe Hospital in Oxford removed a wedge of testicular tissue and froze it in the hopes of one day re-implanting it back into Nathan.
If the procedure is successful, he will have a good chance of becoming a father.
Nathan has a type of tumour called a glioma, which develops from the glial cells that support the nerve cells of the brain.
His tumour is so close to vital brain tissue that surgeons are unable to remove it without causing serious damage to important brain functions.
