Reasons for low sperm motility in men

Many times, what we need to do is to pay attention to our physical health. Our quality of life is also very important. Our quality of life will also affect our life. Then we need to pay attention to our life and then pay attention to our health. This is better. We will pay attention to our own health. Pay more attention to our diet and daily habits.

Asthenospermia refers to a condition in which the number of sperm (grades A and B) moving forward in the semen is less than 50% or the number of sperm with grade A movement is less than 25%. Asthenospermia is also called low sperm motility. The motility of sperm is directly related to human reproduction. Only sperm with normal forward movement can ensure that the sperm reaches the abdomen of the fallopian tube and combines with the egg to form a fertilized egg. Normal sperm after leaving the body is in the semen. Before liquefaction, the activity is restricted. Once the semen liquefies, it immediately shows good motility. If some factors affect the motility of sperm, especially forward movement, it will make it impossible for the sperm to swim to the egg within the best time, and fertilization will not occur. In addition, if the sperm stays in the vagina for too long, the acidic environment will shorten the survival time of the sperm. According to domestic literature reports, about 30% of male infertility is caused by low sperm motility.

Suggestions:

There are many causes of low sperm motility. They can be summarized into the following categories:

1. Infection

Acute and chronic inflammation of the reproductive tract or reproductive glands such as the epididymis, vas deferens, seminal vesicles and prostate can reduce the motility of sperm. The impact of infection on sperm motility can be multifaceted. Microorganisms directly affect sperm, such as mycoplasma, which can adsorb to the head, middle and tail of sperm, so that when sperm moves forward, the hydrodynamic resistance increases and the movement speed slows down, affecting sperm motility and the ability to penetrate egg cells. In addition, mycoplasma can cause partial sperm membrane defects or even membrane structure damage, affecting the fertilization ability of sperm. Escherichia coli can reduce sperm motility by combining with sperm through its own receptors; microorganisms can indirectly affect sperm by producing or releasing toxic substances, Mycoplasma produces NH3 during growth, which has a direct toxic effect on sperm. Escherichia coli can produce sperm inhibitory factors. Infection can also cause a decrease in sperm motility by changing the pH value of semen. When the pH value is lower than 7 or higher than 9, sperm motility decreases significantly. In patients with acute epididymitis or epididymitis, the pH value is mostly alkaline, while chronic epididymitis can cause the pH value to be lower than 7. In addition, the increase in leukocytes in semen caused by inflammation can lead to a decrease in sperm motility through direct and indirect reasons. Insufficient sperm motility caused by prostatitis may be the result of a combination of factors. In addition to microorganisms, leukocytes, pH value and other factors, it may also be related to zinc barriers.

2. Abnormal semen liquefaction

Semen that is not liquefied or has high viscosity is one of the causes of male infertility, and a very important factor may be that it affects the motility of sperm and causes infertility. Thin and long fibrils can be seen in the seminal plasma of semen that is not liquefied, and they are intertwined with each other, reducing the space for sperm movement and restraining sperm. At the same time, thick fibers are also seen to be connected to a network by many thin fibers, which may be the reason for the mechanical restriction of sperm forward movement. The author of this article has used urokinase-type fibroblast activator (uPA) alone in vitro on semen samples that are not liquefied and found that when semen changes from a non-liquefied state to a liquefied state, sperm motility and forward movement ability are significantly improved, and the same effect is obtained by using chymotrypsin.

The above is about the problem of low sperm motility in men. I hope it will be very helpful to everyone. In our daily life, what we need to do is to treat it well. This is very good. It is not only good for our physical health, but also for our quality of life. So we should treat it well and go to the hospital for examination. This is good.
