Strictly speaking, men drinking cola has no direct effect on sperm quality, but drinking large amounts of cola for a long time may lead to obesity and endocrine disorders, which in turn may have an indirect effect on sperm quality to a certain extent. Coke is a carbonated beverage, which contains high levels of sugar. Drinking large amounts of Coke over a long period of time can lead to obesity in the organism. When men are obese, body temperature tends to rise, especially the testicles are the organs that secrete sperm, which are in the groin position, more likely to be damp and hot, and high temperature is a key factor affecting sperm quality, in order to improve sperm quality, weight should be controlled within the standard range, so men need to avoid drinking carbonated drinks such as Coke for a long time. In addition to the increase in body temperature caused by obesity, it also tends to cause endocrine disorders, such as androgen secretion disorder, abnormal testosterone secretion and abnormal pituitary hormone secretion, which can interfere with the formation and maturation of sperm, thus leading to a decrease in sperm quality or a decrease in sperm quantity. In summary, in order to improve the quality of male sperm, you should avoid drinking large amounts of cola for a long time, usually you can participate in more physical exercise, avoid sedentary and stay up late for a long time, and prevent obesity. Also, eat more green vegetables, have a balanced diet, and quit smoking and drinking. In addition, patients should relax, have regular medical checkups, and visit less hot places such as saunas and steam rooms.
