A Positive Pregnancy Test in a Man Identifies Testicular Cancer Though a pregnancy test may provide a hint, most men find out they have testicular cancer when they notice a painless lump in their testicles. Doctors recommend that men undertake self-examinations in the shower to ensure that nothing has changed. If you are a male and pee on a pregnancy test and it comes out positive, you should be concerned. This hormone is generated by pregnant women, but it has also been discovered that testicular cancers produce it. Pregnancy tests, on the other hand, should not be used as a reliable technique of identifying testicular cancer. As Ted Gansler, AMA's head of medical content, says, The presence of higher levels of the hormone beta human chorionic gonadotropin is what a pregnancy test looks for (hCG). Certain kinds of testicular cancer produce this hormone as well. As a result, if a man has increased hCG levels, he may have testicular cancer, resulting in a positive pregnancy test.
