It is said that one drop of sperm in a man is equal to ten drops of blood. Although this statement may be a bit exaggerated, sperm is still very important for men. Sperm is not only a basic requirement for male fertility, but if the sperm motility is poor or poor, it may also affect male fertility issues.
Sperm cannot be seen or touched, how do we know if sperm vitality is good? Moreover, the strength of sperm vitality can to some extent reflect a man's physical problems. So, is a man's sperm vitality good? Strong or not? What is the normal range of sperm motility?
Normal value of male sperm motility
The motility of sperm is generally divided into 5 levels, with level 0 indicating that the sperm cannot move, level 1 indicating poor sperm motility, only crawling in place, level 2 indicating average sperm motility, only moving forward in a curved line, level 3 indicating good sperm motility, moving forward in a straight line, and level 4 indicating excellent sperm motility, moving forward in a fast straight line. Normally, the sum of grades 3 and 4 should exceed 50%, and at least 25% of the motile sperm should move rapidly in a straight line. If the sperm count of grade 0, 1, and 2 exceeds 50% and grade 4 is less than 25%, it is considered weak in motility.
Level I: No vitality.
Level II: Poor mobility.
Level III: Good activity level.
Level IV: Very active. If the activity level is below level II after three consecutive tests, it can be determined as weak assistance.
What factors can lead to low sperm motility
1. The impact of inflammation. When there is inflammation in the epididymis, seminal vesicles, and prostate, abnormal seminal plasma can affect sperm motility and survival in terms of acidity, nutrition, and metabolism.
2. Having anti sperm antibodies in the body can cause sperm agglutination or immobilization.
3. Insufficient trace elements. Especially when zinc deficiency occurs, it can affect sperm motility.
4. Mycoplasma infection. Mycoplasma adheres to the tail of sperm and affects their motility.
5. Due to varicocele, there are problems with local venous blood reflux in the testicles, leading to hypoxia. In addition, abnormal levels of prostaglandins and 5-hydroxytryptamine in venous blood can also cause a decrease in sperm motility.
When male sperm motility is lower than normal or insufficient, it should be noted that low sperm motility is not conducive to male fertility. So, it is important to pay attention to improving sperm vitality and eat more beneficial foods for the body, such as oysters, lean meat, etc.
