What is the normal sperm quality?

Sperm quality is very important to some men, because the premise of conceiving life is healthy sperm. Only when healthy sperm and eggs combine can a healthy baby be conceived. If the sperm quality of male friends is poor or the survival rate of sperm is low, it is easy to cause infertility. Nowadays, many male friends have bad living habits, such as staying up late, smoking and drinking for a long time, which can easily cause poor sperm quality. So, what is the normal sperm quality? Let's find out together.

1. Semen volume: Normal ≥ 2ml. When it is greater than 7ml, it is too much, not only the sperm density is reduced, but also it is easy to flow out of the vagina, resulting in a decrease in the total number of sperm, which is common in seminal vesiculitis; less than 2ml is too little semen, but usually less than 1ml is too little. At this time, the contact area between semen and the female reproductive tract is small, or the viscosity is not conducive to the sperm entering the female cervix, resulting in infertility, which is common in severe paragonitis, low testosterone levels, ejaculatory duct obstruction, retrograde ejaculation, etc.

2. Color: Normal color is off-white or slightly yellow. Milky white or yellow-green indicates inflammation of the reproductive tract or accessory glands; pink, red, or red blood cells under a microscope indicate bloody semen, which is often seen in inflammation of the accessory glands and posterior urethra, and occasionally in tuberculosis or tumors.

3. Acidity and alkalinity: The normal pH value of semen is 72-78. A pH value less than 72 is seen in ejaculatory duct obstruction or urine contamination; a pH value greater than 78 is seen in seminal vesiculitis or old specimens.

4. Liquefaction time: After normal semen is ejaculated, it becomes gelatinous under the action of seminal vesicle coagulase, and becomes liquid under the action of prostate liquefaction enzyme after 15 to 30 minutes. This is semen liquefaction. It is abnormal if semen still does not liquefy 30 minutes after ejaculation.

5. Viscosity: When a glass rod is placed in contact with liquefied semen and gently lifted, a semen thread will form. Normally, its length is less than 2 cm.

6. Sperm count: Generally expressed as the number of sperm per milliliter of semen. The normal count is ≥20×106/ml. A count lower than this value is considered too few sperm, which is seen in spermatogenesis disorders caused by various reasons, and can cause low fertility or infertility due to the reduced chance of sperm entering the uterine cavity and fallopian tubes. If the sperm count is greater than 250×106/ml, it is considered too many sperm, which can also lead to infertility due to its affected motility.

The above is all about the normal sperm quality. Now some male friends have the problem of poor sperm quality, which has a lot to do with men's living habits. If they don't pay attention to developing good living habits and smoke and drink for a long time, it will not be good for the body. If men have plans to conceive the next generation, they should quit smoking and drinking in advance to ensure the quality of sperm.
