Contents of sperm quality test

Sperm quality testing is a relatively common examination item. Generally, men will face this test during physical examinations. After such a test, men can have a more comprehensive understanding of their physical condition. For families who want to have children, sperm quality is very important, and this examination is very necessary. Next, we will introduce you to the content of sperm quality testing in detail.

(1) Sperm survival rate: 30 to 60 minutes after ejaculation, the normal sperm survival rate should be 80% to 90%. Reduced sperm survival rate is an important cause of infertility.

(2) Sperm motility: refers to the activity state of sperm, and also refers to the quality of active sperm. The World Health Organization (WHO) recommends that sperm motility be divided into four levels: ① Good sperm activity, rapid movement, vigorous and powerful, moving in a straight line forward; ② Good sperm activity, fair movement speed, uncertain swimming direction, straight or non-straight movement, with whirlpool; ③ Poor sperm motility, slow movement, spinning or shaking in place, poor forward movement ability; ④ Dead sperm, sperm is completely inactive. Normal sperm motility should be above level ③. If >40% of sperm have poor activity (levels ③ and ④), it is often an important cause of male infertility. Low sperm motility is mainly caused by varicocele, non-specific infection of the urogenital system, and the use of certain drugs such as anti-malarial drugs and androgens.

(3) Sperm count: The normal sperm count is 0.6×1012～1.5×0.012/L, which is equivalent to a total of 400×106～600×106 sperm discharged at one time. When the sperm count value is <20×106/ml or the total number of sperm discharged at one time is <100×106, it is a decrease in sperm, which exceeds the pregnancy limit and leads to infertility. Azoospermia is when no sperm is found in direct semen smear or centrifugal sedimentation. It is seen in congenital testicular dysplasia, malformation or acquired testicular damage and atrophy (such as testicular tuberculosis, inflammation, gonorrhea, endocrine diseases with abnormal pituitary or adrenal function, etc.), vas deferens obstruction or congenital vas deferens and seminal vesicle defects. It is an important cause of oligospermia or azoospermia, and also an important cause of infertility. Checking for sperm is also a way to check the effect of vasectomy. If there is no sperm in the semen after six weeks of vasectomy, it means the operation was successful. If there is still sperm in the semen after two months of vasectomy, it means the operation was unsuccessful.

The above content is an introduction to sperm quality testing. In daily life, men must also pay attention to their physical health. The health of the reproductive system is the most important part of men. Couples who want to do artificial insemination also need to do this test. After passing this test, the chance of conception will be higher, so it should be taken seriously.
