How to check low sperm viability

Sperm survival rate is a very important indicator for men, because if the sperm survival rate is relatively low, then the male's fertility will be greatly affected, and may even lead to the inability to conceive. For this reason, many men will check sperm survival rate during pre-pregnancy checkups. So, how can you detect a low sperm survival rate?

1. Routine examination of semen

The vitality of male sperm is closely related to male reproductive function. It is relatively simple for men to check. You only need to do a preliminary routine semen examination. You can get a specimen container at the hospital. Then choose to take the sample at home and send it to the hospital for examination in time. You can also choose to take the sample at the hospital and then have it checked. Generally, the result of this examination is very fast and can be out in about an hour.

Sperm exists in semen. Routine examination of semen can provide information on semen volume, sperm density, total number of sperm in semen, sperm agglutination, sperm morphology, semen liquefaction, etc. It is the basis for understanding sperm survival rate.

2. Check whether sperm motility is normal

Generally speaking, common factors that affect sperm penetration of cervical mucus include the physical and chemical state of cervical mucus, the activity of seminal enzymes, and the motility of sperm.

3. Biochemical index examination of sperm function

Biochemical indicators of sperm function are very helpful for accurately checking sperm survival rate. There are various biochemical components including enzymes, small molecular organic substances and inorganic substances in seminal plasma.

4. Check for non-sperm cells in semen

Non-sperm cells in semen include immature spermatogonia, spermatocytes, polymorphonuclear leukocytes, macrophages, epithelial cells shed from reproductive organs, lymphocytes, monocytes, etc., which play a very important role in the comprehensive and correct evaluation of non-sperm cells in semen, sperm counting and their motility.

Generally speaking, when the male sperm survival rate reaches 60%-70%, it is considered normal. If the sperm survival rate is lower than this value, it is considered low sperm survival rate. Within 1 hour after ejaculation, the active sperm should be above 70%. If the active sperm is less than 50%, it is abnormal, which is called low sperm motility, also known as asthenozoospermia. If the sperm is completely inactive, it is called necrospermia. Low sperm motility and necrospermia are one of the important causes of male infertility.
