What is the normal sperm motility?

Why are there so many infertile women of childbearing age nowadays? In fact, there are certain physical problems between couples. For example, if the male's sperm motility is abnormal, it will cause great trouble to the female's pregnancy. The male's sperm motility must be kept within the normal range. Only by paying attention to the normal sperm motility in time can we ensure health. So what is the normal sperm motility of men?

Sperm motility refers to the ability or intensity of sperm activity. Active sperm is the most basic condition for penetrating cervical mucus, entering the fallopian tube and combining with the egg cell, so it is one of the contents of routine semen analysis. Under a microscope, the intensity of sperm activity is divided into three levels: in-situ activity is level 1, curved movement is level 2, and fast straight line movement is level 3. Level 3 indicates the strongest activity. For normal fertility, the number of active sperm should be above 70%. If the number of active sperm is less than 50%, it is abnormal. If the sperm is completely inactive, it is dead sperm.

Generally, it is divided into 5 levels: level 0 means that the sperm cannot move; level 1 means that the sperm has poor motility and only moves in place; level 2 means that the sperm has average motility and only moves forward in a curved line; level 3 means that the sperm has good motility and moves forward in a straight line; level 4 means that the sperm has excellent motility and moves forward in a fast straight line. Normally, the sum of level 3 and level 4 should exceed 50%, and at least 25% of the active sperm move in a fast straight line. If the sperm of levels 0, 1, and 2 exceed 50%, and the sperm of level 4 is less than 25%, the sperm has low motility.

① Mild low sperm motility means that the A and B grade sperm are less than 50% but greater than 30% or the A grade sperm are less than 25% but greater than 10%.

② Moderately low sperm motility means that the proportion of grade A and grade B sperm is less than 50%, but greater than 30%, of which grade A sperm is less than 10%.

③ Severe low sperm motility means that the number of grade B and C sperm is less than 30%, and there is no grade A sperm. When sperm motility is low, sperm cannot move forward and it is difficult for them to pass through the cervical canal and uterine cavity to reach the fallopian tube and combine with the egg, thus causing low male fertility or even infertility.

The above content has given you a lot of answers about what is the normal sperm motility of men. In fact, the normality of sperm motility is related to the future pregnancy situation between couples. Moreover, male friends should pay attention to normal sperm motility and maintain it within the most normal range of values. Only in this way can the health of women of childbearing age be guaranteed and it will help pregnancy.
