Walsh and colleagues have reported that men with male factor infertility are nearly three times more likely to develop subsequent testicular cancer. A review of more than 20,000 men who underwent semen analysis determined that oligozoospermic men had an increased risk for testicular cancer compared with fertile control participants.
The incidence of testicular cancer is significantly higher among White men than Black men or Asians and Pacific Islanders; however, Black men tend to present with higher-grade disease and have much worse prognosis than White men.
Recurrent activity, such as horseback or motorcycle riding, local trauma, and increased scrotal temperature, have not been associated with increased risk.
