Incomplete liquefaction of semen may also lead to conception. After the semen leaves the body, under the action of fibrinolytic enzymes in the semen, the proteins in the seminal plasma are broken down, and the semen becomes thin and easy to flow, which is conducive to the activity of sperms. When men’s semen is incompletely liquefied, the sperms in the semen are restricted in their ability to move, only a small number of sperms can enter the vagina and their vitality is poor, and if they are able to pass through the layers of screening and combine with the egg, the woman can be impregnated. It should be noted that when semen is not fully liquefied, the number and vigor of sperm that can successfully enter the fallopian tube decreases, which will affect the combination of sperm and egg, resulting in a lower chance of conception. When patients have incomplete liquefaction of semen, they should be treated as early as possible under the guidance of professional physicians to avoid delaying the condition and leading to adverse consequences.
