What are the causes of low sperm motility?

Sperm motility is a standard for testing the quality of male sperm. Therefore, the level of sperm motility directly affects the quality of sperm. If the sperm motility is low, it may have a certain impact on fertility. Therefore, it is more important for us to understand the reasons that affect the low sperm motility. Only by understanding this knowledge can we improve the quality of sperm. The following will introduce the reasons for low sperm motility.

What is the normal value of sperm motility? Generally speaking, the normal sperm motility is above 60%, and the normal sperm motility is >70% 30-60min after ejaculation. The normal sperm motility is >=40%-50% for grade 2-3 sperm. Within 60 minutes after ejaculation, 50% or more of the sperm have forward movement, and 25% or more have rapid forward movement. Weakened sperm motility or too many dead sperm are the main causes of male infertility.

Men cannot reproduce without sperm. The quality, survival rate and quantity of sperm are directly related to men's fertility. The motility of sperm has a direct impact on men's reproductive function. If the sperm motility is much lower than the normal value, it is likely to lead to male infertility. Therefore, it is very necessary to protect sperm.

What factors may lead to low sperm motility? The main reasons for low sperm motility are as follows:

1. Lack of trace elements. In particular, zinc deficiency can affect sperm motility.

2. Testicular development is blocked. For example, the testicular spermatogenic epithelium is not fully mature or is damaged and thinned, resulting in poor sperm quality and reduced motility.

3. Inflammation. Inflammation of the epididymis, seminal vesicle, and prostate may cause sperm mutation, and its pH, oxygen supply, nutrition, and metabolism are not conducive to sperm activity and survival.

4. Varicose veins. The testicles are partially hypoxic due to venous blood reflux obstruction. In addition, the levels of prostaglandins and 5-hydroxytryptamine in the venous blood increase, which can cause a decrease in sperm motility.

5. Anti-sperm antibodies are produced in the body, causing sperm to agglutinate or stop.

Warm reminder: Sperm is very fragile and easily harmed. Other reasons for low sperm motility include sexually transmitted diseases, bad living habits, work habits, lack of exercise and other factors. Male friends must pay attention to prevention in daily life. Once they are sick, it is recommended to seek timely treatment.

The above is the introduction about the reasons for low sperm motility. As can be seen from the above, there are many reasons for low sperm motility. I believe that after reading the introduction of this article, everyone has a simple understanding of this. Therefore, if you want to improve sperm motility, you must try to avoid these factors that will lead to low sperm motility, so that you can have high-quality sperm.
