Coke does not cause infertility in the human body. Coke has a high caloric value, and a bottle of about 600 ml of Coke has a caloric value of about 300 kcal, which is equivalent to a bowl and a half of rice and a tablespoon of oil that is usually eaten. Excessive intake of cola can lead to an increase in body fat content, energy overload and central obesity. Central obesity is mainly manifested as an increase in visceral fat. Drinking too much cola will lead to more fat accumulation in the viscera, and fat accumulation will bring about a medical phenomenon called insulin resistance, and women are likely to develop polycystic ovary syndrome. Polycystic ovary syndrome can lead to impaired follicle maturation, reduced ovulation, or even non-ovulation in women, affecting fertility. It is important to reduce the intake of carbonated beverages in life, especially for those who are preparing for pregnancy, and to control the total calories, low salt, low fat and light diet. In addition to diet, it is important to increase exercise appropriately during pregnancy preparation, combining aerobic and anaerobic exercise, one hour after meals and greater than 30 minutes per exercise.
