Study Notes
Semen Analysis
Overview
- Also known as seminal fluid analysis or sperm test
- Examination of semen to evaluate male fertility and detect potential reproductive problems
- Typically performed in cases of infertility, low sperm count, or abnormal sperm shape/movement
Parameters Evaluated
- Sperm Count (Concentration)
- Normal range: 15-200 million sperm/mL
- Oligospermia: <15 million sperm/mL
- Azoospermia: 0 sperm/mL
- Sperm Motility
- Normal range: >40% motile sperm
- Asthenospermia: <40% motile sperm
- Sperm Morphology
- Normal range: >4% normal-shaped sperm
- Teratospermia: <4% normal-shaped sperm
- Semen Volume
- Normal range: 1.5-5.5 mL
- Hyperspermia: >5.5 mL
- Hypospermia: <1.5 mL
- pH Level
- Normal range: 7.2-7.8
- Agglutination
- Presence of antibodies against sperm
- Fructose Level
- Normal range: 1.5-5.5 mmol
- Low levels may indicate blockage or absence of seminal vesicles
Abnormal Results
- Oligozoospermia: low sperm count
- Azoospermia: no sperm in semen
- Asthenozoospermia: low sperm motility
- Teratozoospermia: high percentage of abnormally shaped sperm
- Necrozoospermia: high percentage of dead sperm
Clinical Significance
- Helps diagnose male infertility and guide treatment options
- Used to monitor fertility treatment effectiveness
- Can detect underlying medical conditions, such as infections or hormonal imbalances
