Testing a man for STD is a bit different from carrying out the same test in a woman. This is because of a slight difference in the urino-genital systems of men and women. For most men, a simple urine culture and analysis will reveal if the man has an infection or not. This is because the male organ has the same opening for both urine and sperm. It follows that if there is any infection along the urinary tract, a urine test will detect the infection.
In some cases, a pathologist might order a semen analysis and culture if this expert suspects the pathogen has moved into the testes. Another popular male STD test is the VDRL test for syphilis. The popular urethra swab is also used to detect if a man has a urinary tract infection. These tests are easy to carry out and the results are usually reliable.
