Circumcised males are not at an increased risk of testicular cancer. Hence the correct option is 1.
Testicular cancer risk factors include undescended testicles (cryptorchidism), a family history of the disease, and being of white ethnicity. However, circumcision does not appear to be a significant risk factor for testicular cancer. Studies have shown that there is no clear association between circumcision and an increased or decreased risk of developing testicular cancer.
Other factors, such as genetics and hormonal influences, play more prominent roles in determining the likelihood of developing this form of cancer. Therefore, while circumcised males might still develop testicular cancer, the procedure itself does not contribute as a specific risk factor for the disease. Hence the correct option is 1.
