A sperm test is a simple, quick, and completely painless laboratory procedure designed to give an accurate picture of the quantity, quality, and motility of sperm cells in the semen — the three key factors that determine male fertility.

The process step by step: 

1. Preparation
   A period of 3–4 days of abstinence is mandatory before the test. During this time, sexual activity, alcohol consumption, and sauna use should be avoided to ensure the most accurate results. On the day before sample collection, it’s also advisable to avoid excessive coffee or black tea intake, smoking, fatty foods, and hot baths.
2. Sample collection
   The sample is usually collected on-site, in a sterile container, through masturbation. It’s important that the entire ejaculate is collected, as incomplete samples may lead to inaccurate results.
   
   
3. Laboratory analysis
   In the lab, several parameters are evaluated, including:
   • semen volume,
   • sperm count (concentration),
   • motility and morphology,
   • pH level,
   • signs of inflammation or other abnormalities.
     
     
4. Evaluation of results
   The results show whether the semen meets the normal reference ranges defined by the WHO. If deviations are found, this does not necessarily mean infertility — in many cases, lifestyle changes, treatment, or simply time can improve sperm quality.
   
   

Thus, the sperm test is not only a diagnostic tool but also a starting point for further examinations or treatments. It helps identify possible causes of fertility difficulties and supports the development of targeted, effective solutions.
