The amount of semen ejaculated by normal men during sexual intercourse or masturbation is 3-5 ml. Semen is gray-white, slightly alkaline, and has a special fishy odor. This odor is mainly the odor of prostate fluid. Among them, seminal fluid accounts for more than 95%, and sperm accounts for less than 1%. Each cubic centimeter of testicular tissue can produce 2 million sperm per day.

Each male testicle can produce tens to hundreds of millions of sperm every day. Even if these sperm are not excreted from the body, they will age, die, and eventually be digested by enzymes.

The seminal fluid is composed of secretions from the supporting cells of the seminiferous tubules, epididymis, prostate, seminal vesicles, bulbourethral glands and paraurethral glands. The secretions of the seminal vesicles and prostate account for approximately 65% ​​and 30% of the total volume respectively. Seminal fluid mainly provides a matrix for transporting and nourishing sperm, and stimulates sperm motility.

Semen is composed of sperm and seminal plasma. We further analyze that the main component of seminal plasma is water, accounting for more than 90%. Other components include fat, protein particles, pigment particles, phospholipid bodies, amines (bile-containing alkali, spermine, spermine), free amino acids (the content varies greatly, the total amount of amino acids in normal people is 1.25 g/100m1 within 4-6 hours after semen ejaculation), inorganic salts (calcium 25 mg/dl, magnesium 14 mg/ dl, potassium 89mg/dl, zinc 14mg/dl), enzymes (mainly acid phosphatase, lactate dehydrogenase, hyaluronidase), sugars (mainly fructose 224mg/100ml). These components are similar to those of plasma, but their sources, forms and functions are different.

Judging from the ingredients introduced above, semen has basically the same composition as plasma. Then, let’s compare food and semen. A bowl of milk (250 ml) contains 8 grams of protein, 10 grams of fat, and 13 grams of sugar. Gram, a bowl of soy milk (250 ml) contains 11 grams of protein, 5 grams of fat, and 29 grams of sugar. Compared with nourishing the human body, milk and soy milk are much more valuable than semen. In terms of function, semen is not a nutrient, but a need for reproduction.

Due to the lack of sexual knowledge education for a long time, some fallacies have been widely circulated among the people, such as: "One drop of semen, ten drops of blood, loss of semen, great damage to vitality", believing that sperm is the essence of a man, so that some people Believe falsehoods as truth. In fact, semen is neither a supplement containing high nutrients nor a panacea for treating tuberculosis in women. Generally speaking, eating semen has no impact on the body, but the psychological impact cannot be ignored.
