When the semen is just ejected from the body, it will coagulate under the action of coagulase, which looks like jelly-like granular crystals in semen to the naked eye. This is a normal physiological phenomenon, which can protect the sperm injected out of the body.

This jelly-like crystal will gradually disappear in about 30 minutes. This process is called semen liquefaction, which is the function of liquefaction enzyme contained in semen.

If a large number of colloidal crystals still exist after 30 minutes and the semen does not become thinner, it is called non-liquefaction or poor liquefaction of semen. In this case, sperm motility will be greatly affected, which will lead to a decline in pregnancy rate.

You can observe it yourself first, or you can go to the urology department or andrology department of the hospital to check the semen quality to determine whether the sperm quality is normal.
