Why there is no hpv test for men?

Technically, you can: It is technically possible to TEST for HPV in men, but men are not SCREENED nor currently recommended to be screened for HPV. Women are tested as a part of cervical screening and men obviously don't have a cervix to screen. HPV is seen in cancers primarily of the anus and head and neck in men, but population screening is not indicated for these. HPV would be tested for if a tumor developed though.

Several reasons: There's little incentive for companies to make tests for men. Unlike women, in men HPV lesions (warts etc) usually are easy to see and diagnose, so lab test isn't needed. There is no point in testing men without lesions; up to half age 18-25 would be positive, with no treatment. Most such infections never cause disease and testing would not help prevention. Instead of testing, rely on vaccination!
