Testicular cancer rarely causes complications, but the treatment does. Radiation therapy can cause erectile dysfunction which can last a lifetime, especially in older men. Chemotherapy, although rare, can lead to permanent erectile dysfunction, and can cause infertility.
Men with testicular cancer and have lost their sexual desire often have psychological problems. These problems may be due to the fact that they cannot enjoy their sex life.
In addition, men who already had testicular cancer are at increased risk of developing leukemia and other cancers.
