Risk factors
Undescended testicles
Men with undescended testicles which were corrected after the age of 11—13, or which have never been corrected, may be at greater risk.
Low fertility
Men with fertility problems have an increased risk of testicular cancer.
Family history
Having a brother and/or father who has had testicular cancer increases your risk. Research continues to investigate which genes are responsible.
Height
Men who are taller than average have an increased risk of testicular cancer.
Previous diagnosis
A small number of men who have previously been treated for cancer in one testicle may go on to develop cancer in the other.
