Drinking cola will not directly cause infertility and drinking cola will not appear to be spermicidal. Coke contains a lot of sugar, and drinking it for a long time is not really good for the body. Too much sugar intake may lead to obesity and even cause diabetes, and it may also affect oral hygiene. However, cola does not directly kill male sperm, and certainly not female eggs, so it will not directly lead to infertility. However, long-term cola drinking can lead to obesity and diabetes, which may affect fertility due to physical conditions, but proper cola drinking will not have a direct effect on male testicular function. The general food and medications do not have much of a killing effect on male sperm, and it is the immune preparations or anti-tumor chemotherapy drugs that may have a serious impact on the sperm production function of the testicles.
