Function
The Semen Culture and Sensitivity test is a microbiological procedure used to detect and identify pathogenic bacteria or fungi in the male reproductive tract. Once a pathogen is grown (culture), 'sensitivity' testing is performed to determine which specific antibiotics are most effective at killing that particular strain of bacteria.
Why it is Ordered
This test is a cornerstone in the evaluation of male infertility and chronic pelvic pain. Bacteria in the semen can lead to 'leukocytospermia' (white blood cells in semen), which releases reactive oxygen species that damage sperm DNA and reduce motility. It is frequently ordered for patients suspected of having prostatitis, epididymitis, or orchitis, and for those experiencing painful ejaculation or blood in the semen (hematospermia).
Associated Conditions
- Chronic Bacterial Prostatitis: Persistent infection of the prostate gland.
- Male Infertility: Infections can cause ductal obstructions or direct sperm damage.
- Asymptomatic Bacteriospermia: Presence of bacteria without overt symptoms, which can still affect fertility.
- STIs: Detection of pathogens like Neisseria gonorrhoeae or Chlamydia (though specific PCR is often preferred).

Why Context Matters
The most common issue with semen culture is contamination from the skin flora or the distal urethra. If the sample was not collected via a 'clean catch' method (washing hands and penis prior to collection), common skin bacteria like Staphylococcus epidermidis may grow, leading to unnecessary antibiotic treatment. Additionally, many slow-growing or fastidious organisms (like Mycoplasma) require special media and may not show up on a standard culture.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
