What causes low sperm motility?

There are many indicators for evaluating the quality of male sperm, including sperm activity rate, also known as sperm vitality. Obviously, the stronger the male sperm vitality, the better. If a man's sperm vitality is particularly poor, it may be due to asthenospermia. Such sperm has very poor mobility in the female body and it is difficult for it to combine with the male's egg to form a fertilized egg, so it will greatly affect conception. So what are the factors that lead to low sperm activity in men?

What causes low sperm motility?

Male sperm plays a decisive role in female conception. If the quality of male sperm is poor, females will not be able to conceive. Low sperm survival rate is a problem that many infertile men have. When the sperm survival rate is lower than a certain value, the probability of female conception will be greatly reduced, or even infertility. So what causes low sperm survival rate?

1. Reproductive system infection

Reproductive system infection can lead to reproductive system inflammation, such as prostatitis, seminal vesiculitis, epididymitis, and urethritis. These inflammations can cause semen mutations, making the pH, oxygen supply, nutrition, and metabolism of semen unfavorable for sperm activity and survival.

2. Varicose vein

Varicose veins cause testicular hypoxia due to venous reflux obstruction. On the other hand, prostaglandins and 5-hydroxytryptamine in the renal venous blood that flow back into the testicles due to varicose veins can cause damage to the seminiferous epithelium and testicular stroma of the seminiferous tubules of the testicles, reducing the spermatogenic function of the testicles and the function of producing androgens. Varicose veins cause the local temperature of the scrotum to rise, which will also reduce the survival rate of sperm.

3. Production of anti-sperm antibodies

Anti-sperm antibodies are produced by men as a "self-defense" and cause the immune system to produce antibodies, which cause sperm to agglutinate or stop, making it difficult for sperm to survive and resulting in a low sperm survival rate.

4. Testicular development is blocked

The symptoms include incomplete maturity or damage and thinning of the testicular spermatogenic epithelium, poor sperm quality and reduced motility.

5. Lack of trace elements

Zinc is an essential trace element for the human body, especially in testicular development, sperm formation, and maintaining sperm motility. Selenium plays an important role in the human enzyme system and immune system. It is an important component of glutathione peroxidase in seminal plasma (this enzyme can prevent the formation of lipid peroxidation in sperm membranes) and can neutralize the toxicity of cadmium and mercury to reproductive organs. The deficiency of these two trace elements will lead to low sperm survival rate.

This article introduces in detail the five major reasons for low sperm survival rate in men. If you are a man with low sperm survival rate, it is best to carefully refer to the contents of this article to see what the cause of your low sperm survival rate is, so that you can treat it with the right medicine.
