Study Notes
Semen Analysis Introduction
- Semen analysis is a key tool for diagnosing male infertility.
- It's also used in reproductive health evaluations and vasectomy success assessments.
- Learning objectives include understanding gross parameters, sperm counts, morphology, and chemical tests.
- WHO guidelines provide standardized parameters for semen analysis.
Components of Routine Examination
- Key areas covered include gross examination, microscopy (sperm count and morphology), and biochemical analysis.
Gross Examination
- Physical properties assessed include:
- Appearance: Whitish-gray (normal) vs. yellow/red (abnormal).
- Volume: 1.5-7.0 mL (normal range).
- Viscosity: Normal (slightly gelatinous).
- Liquefaction: Within 30 minutes (normal).
Cell Counts
- Sperm Concentration:
- Normal: ≥15 million sperm/mL.
- Measured using hemocytometer or automated systems.
- Total Sperm Count:
- Formula: Concentration × Volume.
Morphological Examination
- Criteria for Normal Morphology: WHO Kruger strict criteria, oval head, intact midpiece, and tail.
- Types of Abnormalities: Head, midpiece, and tail defects.
- Staining Techniques: Papanicolaou, Giemsa.
Common Chemical Tests
- Key Tests:
- pH: Normal range 7.2-8.0.
- Fructose: Indicates seminal vesicle function.
- Zinc and Citric Acid: Prostate function markers.
- Antisperm Antibodies: Detected via MAR or ELISA.
Quality Control in Semen Analysis
- Importance of Quality Control: Ensures reliability and reproducibility of results.
- Standard Protocols: Equipment calibration and staff training. Adherence to WHO guidelines.
Summary
- Key Takeaways:
- Gross Examination: Initial assessment.
- Cell Counts: Quantify sperm concentration.
- Morphology: Assess defects.
- Chemical Tests: Evaluate glandular function.
- Importance of Standardization: Accurate and reproducible results.
Questions & Discussion
- Case Studies: Real-world examples for practice.
- Challenges and Errors: Highlight pitfalls and solutions.
- Open Discussion: Address queries and share insights.
