Study Notes
Seminal Fluid Analysis
Definition
- Seminal fluid analysis, also known as semen analysis, is a laboratory test used to evaluate the quality and characteristics of semen
Purpose
- To assess male fertility and detect potential issues affecting fertility
- To diagnose and monitor infertility, erectile dysfunction, and other reproductive health problems
Components Analyzed
- Semen Volume: Normal range is 1.5-5 mL
- pH: Normal range is 7.2-7.8
- Sperm Concentration: Normal range is ≥15 million/mL
- Total Sperm Count: Normal range is ≥39 million/ejaculate
- Sperm Motility: Normal range is ≥40% motile
- Sperm Morphology: Normal range is ≥4% normal forms
- Agglutination: Presence of clumping or agglutination of sperm
- White Blood Cell Count: Presence of white blood cells in the semen
Abnormal Results
- Azoospermia: No sperm in the ejaculate
- Oligospermia: Low sperm count
- Asthenospermia: Low sperm motility
- Teratospermia: Abnormal sperm morphology
- Aspermia: No semen in the ejaculate
Collection and Processing
- Semen sample is collected through masturbation or sexual intercourse using a specialized condom
- Sample should be kept at room temperature and examined within 1 hour of collection
- Sample is analyzed using a microscope and specialized equipment
