When semen is first ejaculated outside the body, it will coagulate under the action of the coagulase contained in it. To the naked eye, it looks like there are small jelly-like granular crystals in the semen. This is a normal physiological phenomenon that can protect the sperm ejaculated outside the body. These small jelly-like crystals usually disappear gradually in about 30 minutes. This process is called semen liquefaction, which is the function of the liquefaction enzyme contained in semen. If a large number of jelly-like crystals are still present after 30 minutes and the semen has not become thinner, it is called semen not liquefied or poorly liquefied. In this case, the motility of sperm will be greatly affected, resulting in a decrease in the pregnancy rate.

Guidance: It is recommended to eat more foods rich in vitamins and proteins such as vegetables, animal offal, eggs, meat, and soy products, and exercise more to enhance physical fitness. Hope my answer helps you!
