Many men know that one of the most important causes of male infertility is spermatozoosis, which is undoubtedly a kind of injury to many families who want to have children. What is the cause of spermatozoosis? Only by knowing the cause of spermatozoosis can we better help prevent male infertility.
There are many reasons for male spermatozoosis, which is the low survival rate of men's sperm. Dead sperm accounts for a large part of it. If you want to know the origin of spermatozoosis, let's look at the six major causes of spermatozoosis.
Six causes of spermatozoosis
1. Lack of some nutrients necessary for sperm survival in semen
Fructose is an extremely important substance to ensure sperm survival and activity. For example, when there is inflammation in the spermatic duct, the fructose in the normal seminal vesicle fluid will decrease and affect the survival of some sperm.
2. Changes in semen pH
Normal semen pH is 7.2~8.9, slightly alkaline. The pH value of semen in patients with necrospermia is lower than 7.2, and the acidity of semen is higher, which may be the cause of sperm death, while the decrease of semen pH is related to inflammatory diseases of reproductive organs, because bacterial metabolites can cause the decrease of semen pH value.
3. Insufficient oxygen supply
When the reproductive organs are inflamed, there will be hyperemia, edema, blood stasis and slow blood circulation, resulting in the reduction of oxygen provided by blood, and sperm will die due to hypoxia.
4. Decrease of zinc content
The normal content of zinc in semen should be 80~25? G/mL, and when prostatitis occurs, the zinc content in semen can be reduced to 50? Below g/mL, sperm is easy to die.
5. High temperature
Physical factors such as radiation can reduce the survival rate of sperm and cause life-and-death sperm disease due to local high temperature, local exposure to high-dose radiation, or long-term exposure to radiation.
6. Drug factors
Because of taking drugs that can damage sperm, such as tripterygium wilfordii, cyclophosphamide, etc., it can cause sperm death.
