Is semen the same as snot?

Semen consists of sperm and seminal plasma, and the so-called seminal plasma refers to a mixture of various gonadal secretions. Although the number of sperm is large, its volume is less than 0. L% semen, the rest is seminal plasma. 30% of seminal plasma comes from prostate, and the proteolytic enzyme and fibrin hydrolase contained in it are helpful to the liquefaction of semen and sperm passing through cervical mucus plug and zona pellucida of eggs, which is beneficial to pregnancy; Zinc ion is an indispensable substance to maintain sperm activity. 60% of seminal plasma comes from seminal vesicle, and its secretion is alkaline mucus, which contains more fructose and can provide energy for sperm activity. Coagulase participates in the coagulation of semen before liquefaction. 5% ~ 10% of seminal plasma comes from epididymis, ampulla of vas deferens, urethral bulbar gland and paraurethral gland.

Snuff obviously does not have these substances.
