Overview: Sperm Vitality TestIntroduction: The Sperm Vitality Test assesses percentage of live sperm to evaluate male fertility, helping guide treatments for infertility. Affecting 1 in 20 men, infertility poses diagnostic challenges due to varied causes. Following 2023 World Health Organization (WHO) guidelines, it uses microscopy for high accuracy, supporting andrology screening. This test is vital for diagnosis, treatment planning, and improving outcomes in reproductive medicine.
Other Names: Sperm Viability Test, Male Fertility Vitality Assay.
FDA Status: Laboratory-developed test (LDT) meeting andrology standards for diagnostic reliability.
Historical Milestone: Sperm vitality testing began in the 1960s with research by Eliasson, who developed staining methods. Microscopy advancements improved detection, surpassing earlier manual methods.
Purpose: Assesses percentage of viable sperm to evaluate male fertility, guides fertility treatments, and evaluates patients with infertility, aiming to improve reproductive health.
Test Parameters: Percentage of viable sperm
Pretest Condition: Abstinence for 2-5 days required. Collect semen. Report history of fertility issues.
Specimen: Semen (sterile container, 1-5 mL); Semen in sterile container. Transport in a biohazard container.
Sample Stability at Room Temperature: 1 hour
Sample Stability at Refrigeration: 24 hours
Sample Stability at Frozen: Not recommended
Medical History: Document infertility. Include current medications or sexual history.
Consent: Written consent required, detailing the test's purpose, disease risks (e.g., infertility), and sample collection risks.
Procedural Considerations: Uses microscopy with staining to assess viability, requiring labs with skilled technicians. Results available in 1-2 days. Performed in labs with strict handling.
Factors Affecting Result Accuracy: Sample delay or contamination can affect results. Medications or heat may alter viability, requiring correlation.
Clinical Significance: Low viability suggests infertility, guiding therapy. Early treatment might improve outcomes, while untreated cases persist. Normal levels may require other tests.
Specialist Consultation: Consult a urologist or reproductive specialist for interpretation.
Additional Supporting Tests: Semen analysis, hormone levels, or genetic testing to confirm diagnosis.
Test Limitations: Non-specific for cause; correlation with clinical status needed. False results possible with improper staining.
