A. Testicular cancer usually occurs in one testicle and very rarely affects both simultaneously. After the removal of one testicle, the other can still produce enough sperm to maintain fertility, and this does not necessarily mean fertility will be halved. Additionally, factors such as age and overall health also affect fertility.

Radiotherapy used in the treatment of testicular cancer may affect the fertility of the remaining testicle. If there are concerns, fertility preservation should be considered before treatment. For more details, please visit our “Fertility Preservation Support Service Programme”.

A. If only one testicle is removed, it typically will not affect libido and erectile function, as the remaining testicle can still produce testosterone. However, chemotherapy and radiotherapy used in the treatment of testicular cancer may impact sexual function. Erectile dysfunction after cancer treatment is not necessarily permanent; sometimes it can be caused by anxiety. If needed, one can consult healthcare professionals, sex psychologists, or counsellors.

A. The principle of a pregnancy test is to detect the hormone β-hCG, which is released by the placenta during pregnancy. While testicular cancer may raise β-hCG levels if the tumour spreads, most testicular cancer tumours do not release β-hCG. Therefore, it is not recommended to use a pregnancy test for detection.
