What is the reason for sperm

At present, many male friends are under great pressure in life, which will cause many serious consequences. For example, there are problems with sperm. The most common problem is low sperm count. If this happens, it means that the quality of sperm has declined, including the survival rate of sperm. If this continues for a long time, it will affect future fertility. Therefore, we must pay attention to it and improve this situation in time.

First, semen abnormalities are caused by urogenital system infection, such as urogenital tract inflammation caused by various bacteria, viruses, mycoplasma, parasites, tuberculosis, gonococci, etc.; second, semen abnormalities are caused by endocrine dysfunction, such as hypothalamus-pituitary-testicular axis dysfunction, hypothyroidism, hyperthyroidism, etc.; third, semen abnormalities are caused by varicocele; fourth, semen abnormalities are caused by congenital reproductive system abnormalities or genetic diseases; fifth, semen abnormalities are caused by external factors, such as medication, work, living environment and bad habits.

Decreased sperm quality: Decreased sperm quality refers to a decrease in the number, survival rate, motility, and density of sperm at the same volume level.

Low sperm survival rate: Low sperm survival rate refers to sperm survival rate (dead sperm greater than 50%), sperm morphology (normal morphology sperm less than 70%), semen acid phosphatase (less than 25,000-60,000 units/ml), and semen fructose (less than 150-800 mg/100 ml).

Low sperm motility: Sperm motility is an indicator that comprehensively evaluates the quantity and quality of sperm. It includes the number of normally active sperm in semen, i.e. sperm motility, and the quality of normally active sperm, i.e. sperm motility. There is no unified method for diagnosing sperm motility, but it tends to be a 5-level classification method, which is as follows: Level 0 means no motility. Level 1 means poor motility, which means that the sperm only moves in place or rotates. Level 2 means moderate motility, which means that the sperm swims forward in a straight line but is not active. Level 3 means good motility, which means that the sperm has good motility, and Level 4 means very good motility, which means that the sperm swims forward in a straight line very actively. Low sperm motility syndrome refers to sperm motility below Level 2, and the number of active sperm, i.e. sperm motility, is less than 50%.

Low sperm count: Oligospermia is when the number of sperm in semen is lower than that of a normal healthy fertile man. It is now considered that a sperm count of less than 20 million per milliliter is oligospermia. However, clinically, it is often accompanied by changes such as low sperm motility, poor forward motility, and high sperm deformity rate. At this time, it is called asthenospermia. Oligospermia is a common symptom of male infertility.

Too many dead sperm: Necrospermia refers to the situation where all sperm are dead after multiple semen examinations. Under normal circumstances, within one hour of the semen being discharged from the body, the normal viable sperm should be more than 70%. If the dead sperm exceeds 40%, conception will be affected. The sperm survival time should maintain a survival rate of more than 20% for 6 hours. If there are no viable sperm within 6 hours, it can cause infertility.
