Leukocytospermia (also known as pyospermia) is defined as the presence of peroxidase-positive white blood cells (leukocytes) in concentrations exceeding **1.0 million WBC/mL** of semen. It indicates underlying inflammation or active infection within the male accessory sex glands.
How to Read Your Semen Analysis: Leukocytospermia & Inflammation
| Report Parameter | WHO Reference Standard | Diagnostic Flag | Clinical Interpretation |
|---|---|---|---|
| Total Round Cells | < 1.0 million / mL | > 1.0 million / mL | Requires differentiation between white blood cells and immature germ cells |
| Endtz / Peroxidase Test | < 1.0 million / mL | > 1.0 million / mL | Confirms true Leukocytospermia (active inflammatory response) |
| Seminal ROS Levels | Baseline / Low | Markedly Elevated | Granulocyte oxidative burst damages sperm lipid membranes and DNA |
Diagnostic Workup Logic:
- Endtz Test (Myeloperoxidase Staining): Differentiates peroxidase-positive granulocytes (which stain dark brown) from immature round germ cells.
- Semen Bacterial & Atypical Culture: PCR panels for sexually transmitted pathogens (Chlamydia, Gonorrhea, Mycoplasma, Ureaplasma).
- Prostate & Seminal Vesicle Ultrasonography: Assesses calcifications, prostatic duct ectasia, and seminal vesiculitis.
Etiological Stratification:
1. Urogenital Tract Infections: Prostatitis, seminal vesiculitis, or epididymitis caused by pathogens like E. coli or Chlamydia trachomatis.
2. Autoimmune Inflammation: Immune response against sperm-specific antigens or prostate secretions.
3. Toxic or Environmental Factors: Heavy cigarette smoking, severe alcohol exposure, or genital tract trauma.
Clinical Management & Treatment Protocols:
The primary causes are prostate, epididymis, or seminal vesicle infections. Management consists of targeted antimicrobial therapy (e.g., Doxycycline or fluoroquinolones for 14–28 days), high-dose anti-inflammatory vitamins (C and E) to neutralize ROS, and regular ejaculation to flush the sex glands.
