How many days of abstinence is required to check sperm and how to check

How many days of abstinence is required for sperm checking is an issue that couples need to understand in their lives today. We may all know some infertile families. These families are under various pressures from the outside world, so some male friends will check whether there is a problem with their sperm. However, sperm checking involves a problem, which is how many days of abstinence is required for sperm checking. Many people may not know this issue yet. Now I will introduce in detail how many days of abstinence is required for sperm checking and how to check sperm by yourself.

Days:

Human sperm is produced continuously. Even if a normal male collects sperm a short time after sexual intercourse, a large amount of sperm can be found in the semen. However, it is conceivable that the quantity and quality of semen contained in the semen at this time are obviously not as good as the previous time. In order to unify the standards and take into account the impact of semen collection time on semen quality, we generally ask patients to abstain from sex for a period of time before collecting semen.

The best abstinence period is 2 to 7 days, preferably 3 to 5 days. The abstinence period should be counted from the last ejaculation (whether it is sexual intercourse, ejaculation or masturbation). The length of abstinence period mainly affects the amount of semen and sperm density, but has little effect on sperm morphology and motility.

method:

Routine examination is the most important content of semen examination, which generally includes semen color, semen volume, semen liquefaction time, sperm density, sperm 1-hour survival rate, sperm motility, percentage of abnormal sperm, number of white blood cells in semen, etc.

Semen color: Normal semen is transparent grayish white. If abstinence is long, it may be light yellow. If there is inflammation in the reproductive tract, it may be yellow or even contain blood. Semen volume: Each ejaculation volume is 2ml to 6ml, but it is affected by the frequency and number of ejaculations. Less than 1ml/time is called reduced semen volume, and more than 6ml/time is called excessive semen volume, which are all abnormal conditions.

Semen liquefaction time: Semen is in a gel state when it is first discharged from the body, and it will turn into a liquid state after 5 to 30 minutes. This process is called liquefaction. The liquefaction of semen requires the participation of a series of proteolytic enzymes. Viscous and non-liquefied semen is common in patients with prostate or seminal vesicle diseases.

Acidity and alkalinity of semen: Semen is weakly alkaline, with a pH value between 7.2 and 7.8. If the pH is <7, it is acidic, and if the pH is >8, it is alkaline, both of which will restrict sperm function.

Sperm density: Sperm density refers to the number of sperms in each milliliter of semen. Normally, the number of sperms in each milliliter of semen is more than 20 million. If it is less than 20 million/ml, it is oligospermia, which will affect fertility. Sperm 1-hour survival rate The percentage of active sperm within 1 hour after ejaculation should be no less than 60%.

Sperm motility: Sperm motility is divided into four levels: A--fast straight forward movement B--slow forward movement C--swinging in place D--inactivity Normal sperm motility, A-level is not less than 25% or A+B-level is not less than 50%. If it is lower than normal, it is considered low sperm motility. It should be noted that inactive sperm does not mean dead sperm. It may still be alive, but has lost its motility. Eosin staining is often used to determine whether the sperm is dead.

If the abstinence period is too short, the semen volume is often small and the sperm density is also low. However, if the abstinence period is too long, the sperm dead rate may increase due to the prolonged storage time of sperm in the epididymis, which may not reflect the normal situation. Abstinence for 3 to 5 days basically conforms to the sexual life pattern of most people, and the semen test results are closer to the physiological condition of the person.

The above content introduces how many days of abstinence is required and the method of sperm testing. Our male friends may benefit from it. We should also pay attention to some issues in this regard in our daily lives. Don’t wait until the problem happens to you before you regret it, because it will be too late then.
