Sperm smells tasteless, which generally means that the ejaculated semen is odorless, which is an abnormality. Semen belongs to a kind of organic mixture, and its main components contain fructose, protein, prostaglandins and some enzymes and so on. Under normal circumstances, every 1ml of semen will contain 20 million to 100 million sperms, of which protein and fructose are the nutrients of sperms, but also the main components of the odor. The aromatic smell of semen in the clinic is the result of the oxidation of a chemical called arginine in semen, not the smell of sperm. Sperm is a haploid germ cell and an important component of semen, which normally does not have an odor. When the semen smells abnormal, it suggests that there may be urethritis or prostatitis, and you need to go to a regular hospital in time.
