Obesity is also the disaster of sperm killing. Is it scientific to kill sperm with coke

Coke is a very popular drink in summer. The success of the two Coke companies also shows the popularity of Coke. However, in recent years, some male friends are disappointed with Coke, because there is now a saying that Coke kills sperm. Is there any scientific basis for this statement? Does Coke really kill sperm? What is the real killer?

Rumor: Drinking coke reduces sperm and fertility.

Truth 1: From 2001 to 2006, Danish doctor Jensen investigated the sperm quality and caffeine intake of 2554 young men. The results showed that drinking coffee (the total amount of caffeine is below 800mg) and drinking coke (two bottles of 500ml per day) did not affect the number, vitality and morphology of sperm. Do you really drink at least two bottles of coke and at least seven cups of coffee every day? Otherwise, there is no need to worry about the rumors about whether coffee and coke kill sperm.

For very few (3%) young people who drink a lot of coke and caffeine, sperm quality has indeed declined. Dr. Johnson believes that they not only drink Coke, but also have unhealthy eating habits. In other words, drinking a lot of coke is only one aspect of bad eating habits. Therefore, there is no evidence that drinking a lot of coke will reduce sperm quality. It should be noted that although the total sperm count of these people who drink a lot of coke has dropped by 30%, it is still within the range of normal sperm count given by the World Health Organization.

Truth 2: In 1985, Shareea, an obstetrician and gynecologist at Harvard Medical School, USA. Umpierre) doctor and colleagues mixed sperm and coke in vitro to detect the number of living sperm, and reached the conclusion that coke has a certain spermicidal effect. In 987, Hong Chuanyue and others from Taipei Rongmin General Hospital checked the existence of coke and whether sperm has transmembrane transfer activity, and reached the conclusion that coke does not affect sperm activity.

The two studies with completely opposite conclusions won the 2008 Funny Nobel Prize in Chemistry. Regardless of the results of this in vitro laboratory study, it is not scientific to use cola to wash vagina to achieve contraceptive purposes. Because before washing, sperm with a quantity of about 100000 may reach the uterus. Coke's sugar content is easy to cause genital bacterial infection

Moreover, even if Coke does not kill sperm, it will cause other health problems.

The carbon dioxide in cola will stimulate the secretion of gastric juice. Too much acid in the stomach is easy to feel abdominal distension, reduce appetite and reduce daily diet intake. Inadequate intake of nutrients in diet will affect normal growth and development, learning effect, sports performance, work performance and health.
