    Men's sperm plays a fundamental role in women's pregnancy. If the man's sperm quality is poor, the woman will not be able to get pregnant. Low sperm survival rate is a problem faced by many infertile men. When the sperm survival rate is lower than a certain value, a woman's probability of pregnancy will be greatly reduced, and even infertility will occur. So what is the reason for the low sperm survival rate?

    1. Urinary system infection

    Urinary tract infections can cause inflammation of the urinary system, such as prostatitis, seminal vesiculitis, epididymitis, and urethritis. This inflammation can cause genetic mutations in the sperm, causing the pH, oxygen production, nutrition, metabolism, etc. of the sperm to be detrimental to the activity and survival of male sperm.

    2. Seminal varicose veins

    On the one hand, varicose veins cause insufficient testicular oxygen due to obstruction of venous return. On the other hand, prostaglandins, 5-5-hydroxytryptamine, etc., which are injected back into the renal venous blood of the male testicles due to varicose veins, can cause damage between the spermatogenic epithelial cells of the male testicular seminiferous tubules and the male testicular substance, reducing the spermatogenic effect of the male testicles and the effect of male hormones. Varicose veins cause the temperature of the vaginal area to rise, which can also reduce sperm survival rate.

    3. Causes of anti-sperm antibodies

    Anti-sperm antibodies are a "response" produced by men themselves, causing the body's immune system to produce antigens, causing male sperm to agglutinate or inhibit the system, making male sperm unable to survive, resulting in a low sperm survival rate.

    4. Male testicular growth and development is hindered

    The main manifestations are that the spermatogenic epithelial cells of the male testis are not completely perfected or damaged and become soft, and the sperm quality is poor and the charm is weakened.

    five

    , lack of nutrients

    Zinc is an essential nutrient for the human body, especially in the growth and development of male testicles, sperm quality, and maintaining sperm motility. Selenium is vital in the body's enzyme system and human immune system. It is a key component of glutathione lactate dehydrogenase in seminal plasma (this enzyme can prevent male sperm membranes from producing peroxide lipids), and can neutralize the toxic side effects of cadmium and mercury on male reproductive organs. The deficiency of these two nutrients causes low sperm survival rate.

    The article explains in detail the five major reasons why men’s sperm survival rate is low. If you are a man with a low sperm survival rate, then you'd better refer to the content in this article carefully to see what causes your low sperm survival rate, so that you can treat it symptomatically.
