Once the liquefaction of the semen has taken place, the laboratory specialist will proceed to analyze the semen sample under the microscope. This is called sperm microscopic analysis.
This seminal analysis consists of the determination of the following parameters and will be evaluated according to the values considered normal by the World Health Organization (WHO):
- Sperm concentration
- A normal sperm sample must contain at least 15 million sperm per mL of ejaculate.
- Sperm motility
- the percentage of motile spermatozoa (progressive and non-progressive) in the seminal sample must be over 40%.
- Sperm morphology
- According to WHO reference values, a seminal sample must have 4% of normal-shaped spermatozoa.
- i.e. analysis of the living and dead spermatozoa.
In addition to the aspects mentioned above, the existence of leukocytes will also be analyzed. This would be indicative of an infection in the seminal sample.
