Effects of sweetened beverage consumption on semen quality and sex hormone levels in young men Studies have confirmed the effects of caffeinated beverage consumption on semen quality. There are few reports on the effects of sweetened beverage consumption on the reproductive function of young men. A study of 189 healthy men aged 18-22 years was conducted at the University of Rochester in the United States between 2009 and 2010. The results found that the consumption of sweetened beverages was detrimental to sperm motility. Men who consumed more than 1.3 servings/day of sweetened beverages had a 9.8 percentage point decrease in sperm motility compared to men who consumed no more than 0.2 servings/day of sweetened beverages. This phenomenon was more pronounced in people with lean body mass. Therefore, it was concluded that consumption of sweetened beverages has a deleterious effect on sperm motility in young men. Dietary structure characteristics and weak spermatozoa Medical researchers conducted a face-to-face individual questionnaire survey in Tehran, Iran, between January 2011 and December 2011 among 72 patients with weak spermatozoa and 169 men (aged 20-40 years) with normal semen examination. High intake of meat and sweets was found to be a risk factor for idiopathic weak spermatozoa; high intake of fruits, vegetables (especially green vegetables), poultry, skim milk powder and seafood was found to be beneficial in reducing low sperm motility. Suggestions: consume more fruits, green vegetables, poultry, skim milk powder and seafood and limit the intake of meat and sweet products in patients with weak spermatozoa.
