Reason 1: The formula of cola is absolutely confidential.
Coke is a carbonated drink invented in the United States, and the formula of Coca-Cola Company is also a trade secret. Because it is confidential, people can't know what the ingredients of cola are, which also provides soil for rumors.
Reason 2: South American women used to like to clean their vaginas with cola to prevent pregnancy.
Contraceptive measures invented by South Americans in 1950s are said to kill hidden sperm by cleaning vagina with cola after sexual intercourse.
Based on the two reasons mentioned above, many people began to associate it, and finally it was derived as "drinking coke will kill sperm."
What is the truth?
First of all, we need to know what sperm is.
Sperm is a male germ cell. You should know that the environment in which sperm live is particularly sensitive to temperature. First of all, there must be an appropriate temperature. Male testicles are places where sperm are produced, and the temperature there is generally 1~2℃ lower than the body temperature, so the testicles are located outside the abdominal cavity of the human body, which is scientifically reasonable (in contrast, the ovaries that produce eggs in women are located in the abdominal cavity).
It is possible to wash vagina with cola to kill sperm. After all, cola contains a lot of sugar and other ingredients, which can really inactivate sperm. Some people abroad have also done research and found that putting sperm in cola does lead to a decrease in the number of sperm. However, after sexual intercourse, there are a lot of sperm in the vagina. Some sperm can enter a woman's uterus. If it is impossible to simply flush the vagina, they will still move forward and reach the fallopian tube, leading to pregnancy in women. Therefore, the effect of cola contraception is not good. Moreover, the sugar in cola will destroy the microbial environment in vagina and may cause vaginal inflammation.
So, since sperm needs a lower temperature, will iced coke drunk from the mouth kill sperm?
This involves the metabolism of cola in the human body.
Men don't put sperm in coke. Men only drink coke. After drinking cola, cola will be digested and absorbed by the digestive system of the human body. Coke itself can't directly contact sperm, only the metabolites of coke can contact sperm after entering the human body.
Danish doctor Zhan Sen investigated the sperm quality and coke intake of 2554 young men. It was found that drinking cola normally every day did not affect the quantity, vitality and morphology of sperm at all, unless it was a huge intake. So what is this "huge amount"? Experiments show that in order to reduce sperm motility or sperm number, normal men must drink at least two bottles of Coca-Cola every day and stick to it for a long time. This is almost impossible for normal people.
Therefore, whether in theory or in practice, the view that coke kills sperm is unscientific. In other words, if drinking coke can kill sperm, why do you need birth control pills?
Men, don't worry and drink coke boldly.
