The sun is shining on me, I'm dying of heat! How come there are fewer cola juns sweeping through the scorching heat in summer! When you're sweating all over, a glass of ice cola that's completely cool should not be too refreshing!
Where does the saying that Coke kills sperm come from?
There is no answer to this question.
Well, actually, there are two explanations circulating among almighty netizens.
This statement originated in the United States in the 1960s, when the people of the United States engaged in sexual liberation, and car shocks were prevalent among men and women. After that, women would insert bottled cola into their vagina to rinse semen to achieve contraception. Later, it was somehow passed on to drinking cola to kill sperm.
Some people say that this rumor was spread by people from Harvard University 30 years ago. It is said that a Harvard scientist conducted a great experiment at that time. He placed sperm in alcohol, coffee, cola, and milk, respectively, to observe the vitality of sperm, and then came to the conclusion that alcohol kills sperm, coffee kills sperm, and cola kills sperm, but cola kills sperm is the most widespread and influential.

Can Coke Really Kill Sperm?
After the sperm has been ejaculated, let alone put it in cola coffee. Even if it's put in the air, it won't last for half an hour!
Today, looking at the experiment and its conclusions from a scientific perspective is indeed riddled with flaws. Coke is used for drinking and must first enter the digestive system, having nothing to do with the reproductive system. "Any beverage first reaches the stomach for digestion and absorption, and then the blood transfers the nutrients to various parts of the body. Coke spermicidal effects do not occur in the human body.".
In addition, the practice of using cola to rinse the vagina after the event to achieve contraceptive purposes is also very unscientific. "Before washing, sperm with a number of around 100000 may have reached the uterus, and the sugar in cola can also easily cause bacterial infections of the genitals.". In today's advanced contraceptive methods, safer and more effective methods should be chosen.
What? Do you still believe it?
Between 2001 and 2006, Danish doctor Tina Kold Jensen investigated the sperm quality and caffeine intake of 2554 young men. The results showed that daily consumption of coffee (with a total caffeine content of less than 800 mg) and cola (in two bottles of 500 ml per day) did not affect the number, vitality, and morphology of sperm at all. Do you really drink at least two bottles of cola and at least seven cups of coffee every day? If not, there is no need to worry too much about rumors about whether coffee and cola are spermicidal.
For a very small number (3%) of young people who consume "significant amounts" of cola or caffeine, some of them do have a problem with decreased sperm quality. Dr. Johnson believes that these people not only drink more cola, but also have other unhealthy eating habits.
In other words, drinking "huge amounts" of cola is just one aspect of bad eating habits. Therefore, there is no evidence that drinking large amounts of cola causes a decrease in sperm quality. It should be noted that although the total sperm count of those who consume large amounts of cola has decreased by 30%, they are still within the normal sperm count range given by the World Health Organization.
