Leukocytospermia and semen infections: symptoms and DFI impact

What is Leukocytospermia?

Routine semen reports frequently note "Round Cells: 2 to 4 million/mL." In standard brightfield microscopy, it is impossible to distinguish between immature round spermatids (harmless precursor germ cells) and white blood cells (leukocytes).

To confirm true leukocytospermia, an andrology laboratory must perform specialized Endtz Peroxidase Staining. Only true leukocytes contain peroxidase enzymes that turn dark brown. - WHO Threshold: > 1.0 × 10^6 peroxidase-positive leukocytes / mL.

Why Are White Blood Cells in Semen Dangerous?

Neutrophils and macrophages in seminal fluid produce up to 1,000 times more reactive oxygen species (ROS) than abnormal sperm cells themselves: 1. Membrane Lipid Peroxidation: Attacking polyunsaturated fatty acids in the sperm tail, stripping forward progressive motility. 2. Acrosome Premature Reaction: Causing sperm to release digestive enzymes prematurely, rendering them incapable of fertilizing an egg. 3. Severe DNA Strand Breaks: Generating elevated Sperm DNA Fragmentation Index (>30%), leading to early embryo arrest and recurrent miscarriages.

Common Etiologies & Proven Therapies

• Chronic Bacterial Prostatitis: Often asymptomatic or presenting with mild perineal discomfort or urinary frequency.
• Ureaplasma & Mycoplasma Genitalium: Hidden atypical microorganisms requiring targeted molecular PCR or enriched culture.
• Targeted Clinical Treatment: A 2 to 3-week course of lipid-soluble broad-spectrum antibiotics (such as Doxycycline or fluoroquinolones) that penetrate the prostate-blood barrier, combined with oral Vitamin C, Vitamin E, and frequent ejaculation to flush the accessory glands.
