How to tell if sperm is alive?

There are many reasons that affect the quality of a man's sperm, such as his physical constitution. In addition, men have many bad habits, such as frequent smoking and drinking, etc., which will affect the quality of sperm. There are many indicators to judge a man's sperm, such as sperm vitality, sperm deformity rate and sperm motility, etc. The sperm just ejaculated is generally alive, and after a certain period of time, the sperm will die. The following will teach you how to judge whether the sperm is alive.

How to tell if sperm is alive?

It is impossible to determine whether sperm is dead or alive with the naked eye. Generally, sperm cannot survive for a long time after being liquefied in vitro, and cannot exceed 48 hours. If it's vaginal, it may be 48 hours.

Suggestions: Therefore, it is recommended to go to the hospital's men's department for a semen analysis to determine the quality of sperm. In general, be careful not to worry too much.

A urinary tract infection is an inflammation caused by bacteria directly invading the urinary tract. Common urination abnormalities caused by urinary tract infection are frequent urination, urgency, and pain when urinating. Urinary incontinence and urinary retention may also occur.

Suggestions: The treatment plan for prostatitis is generally a combination of drug therapy and physical therapy. Physical therapy accelerates blood circulation through sound, light, electricity, etc. to promote the dissipation of inflammation. If necessary, targeted drugs can be selected through drug sensitivity tests. It is recommended to go to a regular hospital for examination and treatment as soon as possible, and do not take medicine blindly to avoid serious consequences. I wish you good health.

Alternatively, a term sometimes used is "total motility," which refers to the fraction of sperm that show any type of movement. This concept is rarely used in the assessment of animal semen but is the norm for describing human sperm motility.

There is considerable variation between species in what is considered normal or acceptable vitality. For example, through the breeding sanity check, it is recommended that multi-sires have greater than 30% progressive motile sperm, stallions greater than 60% and dogs greater than 70%. Normal people generally have more than 50% total sperm motility.

When analyzing motility, it is important to know if the semen sample has been abused in any way. Exposure to heat, cold, any kind of residue on the collection equipment, or the wrong pH or osmotic pressure of an extension can adversely affect peristalsis. Also affected by periods of sexual inactivity - men who have not ejaculated for a long time usually have poor motility on the first ejaculation, but better motility in collecting the second ejaculation shortly thereafter.

Sperm motility assessment techniques

There are several ways to evaluate exercise. Which technique to use depends on operator experience, the desire for precision and repeatability, and equipment availability. In almost all cases, the percentage of motile spermatozoa reportedly exhibited motility (usually progressive motility).

Manual motility estimation (wet mount): This commonly used technique involves placing a diluted semen sample on a microscope slide, examining it with a microscope, and estimating the proportion of the population that is motile.

More specifically, dilute the semen sample in warm extension or buffer and pipette approximately 10 to 20 μl of this sample onto a clean, pre-warmed microscope slide. Lower the coverslip onto the sample, avoiding the formation of bubbles if possible, and examine the slide on a microscope using a 20x objective. At least ten widely spaced field studies have provided an estimate of the percentage of motor cells. If estimating motion is a commonly desired technique, a microscope warm stage may be worth purchasing.
