What factors are decisive for sperm motility?
The reasons why a couple fails to fall pregnant can lie with either the man or the woman, or both partners. The most common reason for infertility in the man is insufficient production of normally shaped, motile sperm cells. According to the guidelines of the WHO, “normal” sperm motility is defined by the following values:
- amount of ejaculate: 2 ml or more
- pH-value of the ejaculate: 7.2 or more
- total number of sperm cells in the ejaculate: at least 40 million sperm cells
- sperm concentration: at least 20 million sperm/ml
- morphology of the sperm: at least 15% normally formed
- sperm motility: at least 50% with forward movement or 25% with progressive movement within 60 min. after ejaculation
We establish the details of sperm production and quality with a sperm analysis performed in our labs. Based on the results of the sperm analysis, we then advise you concerning further diagnosis and treatment methods.
