Does milk tea kill sperm? It depends

Milk tea is an essential drink in life and a favorite of many people. Studies have found that drinking milk tea in moderation has no effect on the body, but long-term excessive consumption can kill sperm and even cause infertility.

1. Long-term drinking of milk tea affects sperm quality

Most bubble milk teas on the market contain neither "milk" nor "tea". It is an open secret in the milk tea industry to use creamer instead of fresh milk to make milk tea. Most milk tea is made of creamer, tea powder and other substitutes such as flavors and pigments. Creamer is not milk or cow's milk product, and the tea alkaloids and tea polyphenols content of tea powder are very low. The brewed drink cannot be called "tea" at all.

It is worth noting that the main ingredient of creamer is hydrogenated vegetable oil, which contains trans fatty acids.

Experts say that trans fatty acids in food enter the human body and participate in the metabolism of fatty acids in the human body. Long-term and excessive intake of trans fatty acids will not only increase the incidence of cardiovascular diseases and tumors, but also have a greater impact on reproductive health. On the one hand, it affects the quality of sperm and egg cells, increasing the risk of infertility and fetal malformations; on the other hand, trans fatty acids affect hormone synthesis, and disorders in the synthesis of sex hormones can lead to irregular menstruation, sexual dysfunction, and increase the chance of infertility.

2. Drinking milk tea occasionally will not induce infertility

Of course, we cannot go too far. Trans fatty acids are just unhealthy food ingredients, not toxic substances. There is a safe limit for their intake. The harm of trans fatty acids to the human body is caused by long-term chronic effects and will not be seen immediately. Foods containing hydrogenated vegetable oils may contain trans fatty acids, such as biscuits, bread, French fries, fried chicken nuggets, etc. Milk tea is just one of them.

There are currently no clinical cases showing that simply consuming a certain food ingredient can cause male infertility. There are many factors that affect male infertility, such as endocrine factors, congenital factors and exogenous factors. Experts believe that drinking milk tea occasionally will not cause male infertility. But it is worth noting that long-term drinking of milk tea is ultimately harmful to health. It is understood that in addition to milk tea, foods with high trans fatty acid content include instant oatmeal, cream cakes, bread (especially those with high butter and shortening content), crispy biscuits, potato chips, etc. Couples of childbearing age should eat less of these foods.
