Can regular consumption of strong tea and drinks affect male reproduction?

Many people in the time of medical care, doctors often say: “drink more plain water, less strong tea, drinks”, but many people have not been able to understand, in the end for what. Tea polyphenols in tea has an antioxidant effect, good for cardiovascular health, but also good for the health of reproductive cells, appropriate drinking tea, should be a good thing. However, there must be higher requirements for the hygiene of tea, because the concentration of toxic heavy metal ions such as lead, cadmium and mercury in poor quality tea is high, too much intake is not good for sperm production, reduced vitality, and can even lead to sperm deformities. There are many kinds of beverages on the market, and young people prefer alcoholic beverages and flavored beverages. The ethanol contained in alcoholic beverages can lead to an increase in catecholamines in the blood. The physiological effect of catecholamines is to cause vasoconstriction. Excessive concentrations of catecholamines can affect the blood flow in the testes, causing premature shedding of immature sperm, which is not conducive to the maturation of sperm in the epididymis and can lead to atrophy of spermatogenic epithelial cells. If the concentration of alcohol in the body is greater than 80mg/L, there is a certain effect on sperm. Even if the alcohol content in the beverage is not high, drinking too much of the total amount will also have hidden dangers when it accumulates in the body. The fermentation of alcohol produces an estrogen-like effect, which inhibits sperm motility and leads to low fertility levels in men. Alcoholic beverages also contain a lot of purine substances, which, in concert with alcohol, can lead to an increase in blood uric acid. Long-term consumption of large amounts of alcoholic beverages can lead to uric acid deposition, resulting in kidney tubular blockage and kidney failure. At the same time, alcoholic beverages can also excite the sympathetic nerves of the human body, making the body in a state of increased respiration, increased blood flow and vasoconstriction, so it will feel invigorated. The neurovascular reflexes such as glandular secretion and erection are innervated by the parasympathetic nerve. When the sympathetic nerve excitement, the parasympathetic nerve is in a state of relative inhibition, there will be hypersexuality. So, when men drink a few more cups of brewing romance at the same time, “sex” will actually be greatly reduced. Flavored drinks, pearl milk tea and carbonated drinks are the most prevalent. The pearl milk tea contains a large amount of trans fatty acids, which will reduce the secretion of androgens and have a negative impact on sperm production. Long-term consumption of sugary beverages can lead to reduced sperm motility. Interestingly, this association is more pronounced in lean men. Sugary beverages increase the risk of insulin resistance, which can harm spermatogenesis. Carbonated beverages, most of which have carbonic, citric and lactic acid content, tend to interfere with male semen properties and affect sperm survival. The combined effect of acids, additives, preservatives and caffeine in carbonated beverages can reduce sperm vitality to some extent, leading to an impact on male fertility. Therefore, beverages are not consumed in excess to be more healthy.
