Rumors: Drinking cola to reduce sperm and reduce human fertility.
The truth 1: From 2001 to 2006, Danish doctors investigated the sperm quality and caffeine intake of 2,554 young men.It was found that drinking coffee (total caffeine is less than 800mg), and drink cola (two bottles of 500ml per day) at all.
For very few (3%) young people who drink cola or caffeine, some of them do have the problem of decline in sperm quality.Doctors believe 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 to prove that a large amount of cola has caused sperm quality to decline.It should be specifically explained that although the total number of sperm sperm has decreased by 30%of these huge amounts of cola, it is still within the total number of normal sperm given by the World Health Organization.
Truth 2: In 1985, experts mixed sperm and cola in vitro to detect the number of sperm sperm, and concluded that Coke had a certain effect of killing sperm; in 1987, experts tested whether the sperm still had cross -membrane migration under the existence of cola.Activation is concluded that Coke does not affect sperm activity.
Carbon dioxide in Coca -Cola can stimulate the secretion of gastric juice, too much gastric acid can easily feel abdominal distension, reduce appetite, and reduce daily diet.Insufficient nutrient intake in diet will affect normal growth and development, learning effects, exercise performance, work performance and physical health.
A can 355ml of cola, which contains about 35 grams of sugar, is equivalent to 140 calories, which is equivalent to the calories of half a bowl of rice.However, only the calories are equal, but the nutrients are different. Because sugar contains only heat, other nutrients are not at all.It is easy to develop sweet and bad eating habits, and only like to drink sweet water without drinking boiled water. In addition, sugar also has a bad effect on the health of the teeth.
The killer who really kills essence
1. Smoking and drinking
Studies have found that men with more than 31 smokers or more than 10 years of age have a significant decrease in sperm number and sperm vitality, and deformity sperm has doubled.Alcohol is a kind of gonadotoxin. If you drink too much drink, you can poison the adenia. Men are manifested as testicular damage, testicular atrophy, weakening reproductive function, blood testosterone levels in bloodWeaken, can induce ED and not ejaculate.
2. Human body obesity
In recent years, the incidence of obesity has risen year by year and has become a social problem that affects people's physical and mental health.The obese people did not have obvious conscious symptoms in the early days, but there were many hidden dangers, especially male obesity, which would affect the development of reproductive systems such as testicles and penis.Its pathogenesis is that adipose tissue has the characteristics of transformingrogestyls into estrogen, reduces male androgen in men, increases estrogen relatively, hinders sperm production and affects sperm quality.Obese can also induce hypertension and diabetes, which can cause physical dysfunction.
3. Environmental pollution
In our environment, air, water, and soil contain many chemicals that affect human reproduction, such as harmful metals such as lead, mercury, cadmium, pesticide pesticides, and some drugs taken by people.Possession of sperm.Experts point out that men's sperm reduction is mainly caused by environmental factors caused by chemicals, and these chemical substances can cause degeneration and atrophy of male reproductive systems, abnormal mating behaviors and the role of hormone receptors that affect the human body, which will affect the hormone receptor of the human body, which will affect the hormone receptor of the human body, which will affect the human body, which will affect the human body, which will affect the human body, which will affect the human body, which will affect the human body, which will affect the human body, which will affect the human body, which will affect the human body, which will affect the human body, which will affect the human body, which will affect the human body, which will affect the human body.The development of the embryonic reproductive system causes the feminine of the next generation of male embryo, the testicular becomes smaller, and the sperm decreases.
4. flood
In recent years, sexually transmitted diseases have been spread, and the flood of drugs has helped the spread of sexually transmitted diseases.This is a major harm of biological factors to human reproduction.Most sexually transmitted diseases will not only cause inflammation, damage, and change structure of reproductive systems. Many diseases can also directly affect the formation of reproductive cells, induce genetic mutations, sperm malformations or immune response, produce anti -sperm antibodies, and kill sperm cause infertility.
5. Nuclear heat radiation
Nuclear radiation is more destructive for testicles.Because testicles are one of the most sensitive organs in nuclear radiation in human organs.Low doses can also reduce sperm quality, and even cause temporary spermless.Some experts estimate that the radiation dose of 200 & mdash; 300 Lunqin can cause dysfunction.X -rays can cause sperm malformations, decreased quality, small dose X -ray irradiation can destroy the genetic genes of sperm cells, or cause sperm head abnormalities, causing fetal malformations, abortion, premature birth or mental retardation; heat radiation is also important to cause sperm quality.reason.Experts believe that if the temperature of the testis is more than 45 ° C, it can hinder sperm production and sperm activity in two hours.Sauna baths, bathing with overheated water, high temperature operations, wearing tight pants, etc., can damage the ability of testicular to make sperm and sperm activity.
6. Electromagnetic effects
In today's society, people's living standards have improved, and the use of various electrical appliances, such as computers, color TVs, air -conditioning machines, refrigerators, electric blankets, mobile phones, laser photos, dense radio launch devices, etc.Frequent electromagnetic waves.Although there is no trace, it quietly affects the human body's birth cells, kills the sperm relentlessly, and makes people prevent it.
Reminder: The problem of cola killing, male friends do n’t have to worry, but the diseases such as Hypertension caused by cola will still indirectly affect the fertility function, so do n’t drink more cola.
