The combination of acidic substances, additives, preservatives and caffeine in carbonated drinks will reduce sexual ability, limit sperm motility and affect male fertility to some extent.
According to a recent article published by the American Overseas Chinese News, experts from Harvard Medical School conducted experiments on killing sperm with three different formulas of cola drinks on the market, and reached the conclusion that drinking cola drinks by newly married men will directly kill sperm, thus affecting men's reproductive ability. If the injured sperm is combined with the egg, it may lead to fetal malformation or congenital deficiency.
Extended data:
Don't give these drinks to men who are pregnant after spermicide.
The health of sperm is very important for pregnant men, but some drinks on the market will have a great impact on the body, which will easily lead to the weakening of sperm vitality and the increase of oxidative stress. This phenomenon will seriously affect the survival of sperm, especially for men.
1, beer
Wine has always been regarded as a friend of men, but it is also the most harmful to men. Not only beer, but also drinks containing alcohol (ethanol) have spermicidal effect.
Alcohol contained in alcohol will lead to the increase of catecholamine in blood. The physiological function of catecholamine is to contract blood vessels. Excessive concentration of catecholamine will affect the blood circulation of testis, cause premature shedding of immature sperm, which is not conducive to sperm maturation in epididymis, and also lead to atrophy of spermatogenic epithelial cells.
If the alcohol concentration in the body is greater than 80 mg/L, the damage to sperm will be obvious. Even if you drink low-alcohol wine, there will be hidden dangers if you drink too much.
After the hops in beer are fermented, it will produce an estrogen-like effect, which will inhibit the mobility of sperm and lead to the low fertility level of men. Beer also contains a lot of purine, which, with the cooperation of alcohol, leads to the increase of serum uric acid. Drinking a lot of beer for a long time will cause uric acid deposition, leading to renal tubular obstruction and renal failure.
2. Milk tea
Bubble tea contains a lot of trans fatty acids, which will reduce the secretion of androgen (testosterone), have a negative impact on sperm activity and interrupt the reaction process of sperm in the body. Therefore, it is recommended to drink less. If you really like to drink milk tea, you can make milk tea with milk, condensed milk and black tea.
3. Coffee
Caffeine in coffee can excite the sympathetic nerve of human body, making human body in a state of accelerated breathing, increased blood flow and vasoconstriction, so it will feel refreshed. Neurovascular reflexes such as gland secretion and erection are dominated by parasympathetic nerves. When sympathetic nerve is excited, parasympathetic nerve is in a state of relative inhibition, and sexual desire will decrease.
4. Whole milk
A study shows that adult men eat full-fat dairy products every day, such as cheese or milk, and the number of viable sperm decreases. Scientists say that adolescent men should drink whole milk, but adult men may have sperm problems when they eat whole milk. Just switch to low-fat milk.
In addition, male friends should also pay special attention to the way of drinking tea. If they drink inferior tea, it will not be conducive to cardiovascular health, and it is often easy to induce some mental diseases, and it will also lead to abnormal sperm, so we must pay attention to it as soon as possible.
