So how fast is sperm dissociation normal?
In the laboratory tests for male infertility, of course, the first to bear the brunt is the semen test. Routine semen examination indicators include: semen volume, color, pH, agglutination, liquefaction, sperm count, sperm motility, etc.
How fast is the speed of sperm?
Sperm motility is a very important indicator, but in the past, subjective judgment was solely based on the results observed by the naked eye under a microscope. It is not only influenced by the technical level of the examiner, but also has considerable subjectivity.
Some laboratories grade and record sperm movements according to the methods prescribed by the World Health Organization, while others only make a rough assessment and record them as good, medium, and weak. Therefore, semen testing has been at a low level. In the 1970s and 1980s, foreign countries have successively developed laser light scattering measurement technology and computer image processing automatic analysis systems, which have brought the level of semen examination to a very accurate and complete level.
According to the test, the distribution peak of sperm motion velocity in normal people is 36 microns/second, with an average motion velocity of 35 microns/second, while the distribution peak of sperm motion velocity in infertile patients is 32 microns/second, with an average motion velocity of 31 microns/second, with significant differences between the two groups.
According to clinical statistics, about 20% of male infertility patients are azoospermia, about 30% are oligozoospermia, and about 40% of human sperm movement speed is lower than 31 microns/second (half of which is lower than 28 microns/second).
Due to the fact that a significant proportion of male infertility patients appear to have normal semen tests, but their sperm motility is actually low. Therefore, we preliminarily believe that if a person's average sperm motility is lower than 28 microns per second, it should be considered asthenospermia (i.e., poor sperm motility, or poor sperm motility).
