متن کاملAntioxidant intake is associated with semen quality in healthy men.
BACKGROUND We seek to determine whether dietary and supplement intake of specific micronutrients (zinc and folate) and antioxidants (vitamins C, E and beta-carotene) is associated with semen quality. METHODS Ninety-seven healthy, non-smoking men provided semen and were interviewed. Average daily nutrient intake from food and supplements was derived from a self-administered food frequency ques...
متن کاملSerum lipid profiles are associated with semen quality
We aimed to explore the associations between different lipid profiles and semen quality in a large-scale general male population. Sperm concentration, total sperm motility, progressive motility, and normal sperm morphology of total 7601 participants were recorded. The association of these semen parameters with the triglyceride, total cholesterol, high-density lipoprotein, low-density lipoprotei...
متن کاملTobacco smoking is associated with decreased semen quality
BACKGROUND Tobacco smoking is a public health issue and has been implicated in adverse reproductive outcomes including semen quality. Available data however provides conflicting findings. The objective of this study was to evaluate the effect of tobacco smoking on semen quality among men in Ghana. METHODS In this study, a total of 140 subjects were recruited, comprising 95 smokers and 45 non-...
