Yes, and no: Chlamydia trachomatis is an obligate intracellular gram-negative microbial organism, sexually transmitted,can cause trachoma (granular conjunctivitis), urethritis, pelvic inflammatory disease, lymphogranuloma venereum, and pneumonia. Tests for Chlamydia trachomatis include: urine DNA probe, urethral or endocervical or vaginal swab. However, other sexually transmitted diseases need to be tested.

No: A semen analysis is not needed to diagnosis something simple like chlamydia. You can just ask for a chlamydia test. This can be done on urine or a urethral swab.
