The semen test curve speed is mainly used to assess the viability of sperm, and weak spermatozoa can be ruled out based on the speed of the test. Under normal circumstances, the sperm curve speed test value is 41.61um/s, while the straight line speed of sperm can reach 34μm/s. The straight line and curve values of sperm can be used to provide feedback on the viability of sperm, and can also be used as a diagnostic criterion. If the semen examination finds that the curve speed is too fast or too slow, it is mostly suggestive of a decline in sperm viability, and is considered to be related to weak spermatozoa, which, if left untreated, can easily affect male fertility. If the speed of the semen curve is too fast or too slow, the total number of sperm, sperm density and other indicators should be tested and the sperm quality should be analyzed according to the percentage of sperm movement. If there are abnormalities in the test, it is recommended to consult a doctor promptly.
