How is the testing for HPV performed on the donors?

We test the semen of our donors for HPV at the time they are being screened for initial donor eligibility, and thereafter every three months while they are donating. By testing semen samples at 3 month intervals, we increase the chances of detecting the presence of HPV earlier than via the visual detection methods typically performed during a routine physical examination given at 6 month intervals in most tissue banking operations.
