Semen status is an important basis for men to judge their own reproductive and sexual abilities. But what should normal semen be? What problems do different changes in semen reflect?
Semen volume - normal volume should be more than 2ml (ml). If there is more than 7ml, not only the sperm density will be low, but also the sperm will easily flow out of the female vagina, and the total number of sperm will be low, which is very common in patients with seminal vesiculitis. If the total volume is less than 2ml, the sperm volume is small, and if the volume is less than 1ml, it is easy to be sterile.
Color - The normal color is gray white or slightly yellow. If the semen appears milky white or yellow-green, it indicates that there is inflammation in the male reproductive tract or accessory gonads. Red blood cells can be seen in pink, red or under the microscope. They are bloody semen. They are common in patients with paragonads and post-urethritis, and occasionally in patients with tuberculosis or tumor.
Liquefaction time - after normal semen injection, it will become gelatinous under the action of seminal vesicle coagulase, and become liquid under the action of prostate liquefaction enzyme after 15-30 minutes, which is called semen liquefaction. It is abnormal that semen does not liquefy after 30 minutes of injection.
Viscosity - touch the liquefied semen with a glass rod and gently lift it to form semen silk. If the semen is normal, the length of the semen filament should be less than 2 cm.
In addition, semen pH, sperm motility and other indicators need to be tested to get accurate results. If men find that the above four indicators are not normal, they should go to the hospital for further laboratory examination.
