Semen Analysis

 

SA is a scientific examination of semen fluid using microscope to investigate male infertility or effectiveness of vasectomy. The parameters and the normal values commonly used are the one standardized by World Health Organization (WHO).

 

In order to obtain an accurate analysis, the instructions listed below should be complied for sample collection:

  • 3 to 5 days of abstinence prior to sample collection
  • inform the nurse if you were sick or on any medication for the past 2 months
  • collection by masturbation is preferred
  • do not use lubricant, soap or perfume during sample collection
  • aviod spillage when sample is collected
  • the sample must be delivered to the lab within one hour after ejaculation
  • the analysis is preferably done at fertility centre

 

In the laboratory, after the sample liquefies, the criteria below are determined:

 

Semen Characteristic
Normal Ranges
Volume (ml)
≥ 2.0
pH
≥ 7.2
Concentration (M/ml)
≥ 20
Total Sperm Count (M)
≥ 40
Motility (%)
≥ 50
Normal Morphology (%)
≥ 30
WBC (M/ml)
< 1.0

 

 

 

However, the accuracy of the semen analysis might be affected by individual variability, environmental and physiological factors. You are advised to repeat the test after 3 months if your result is abnormal. A man cannot be diagnosed as infertile as long as there are alive sperm in the semen.

 

You may improve the quality of your semen by:

1. avoiding alcohol intake,
2. avoiding smoking,
3. avoiding high temperature places such as spa, hot bath, spring etc,
4. taking zinc or vitamen E supplement, and
5. taking antibiotic subscribed by doctor if there is high count of WBC in your semen.
