siemennestenäyte

Siemennestenäyte, often referred to as a semen analysis, is a laboratory test used to evaluate the fertilizing capacity of a male's semen. The primary purpose is to assess male fertility, but it can also be used to confirm successful vasectomy or to analyze semen following sexual assault.

The procedure involves collecting a semen sample, typically through masturbation, in a sterile container. The sample is then transported to a laboratory for analysis. Several parameters are assessed, including semen volume, sperm concentration (the number of sperm per milliliter), sperm motility (the percentage of sperm that are moving), and sperm morphology (the shape and structure of the sperm). Other factors like pH, viscosity, and the presence of white blood cells may also be examined.

A normal semen analysis indicates a higher likelihood of fertility, while abnormal results can suggest potential fertility issues. These issues can stem from various factors, including infections, hormonal imbalances, genetic conditions, lifestyle choices, or physical obstructions. If an abnormality is detected, further investigations or treatments may be recommended. For vasectomy confirmation, the analysis checks for the absence of sperm in the ejaculate, indicating the procedure's success.
