Dietetic habits revealed significant effect on seminal plasma vitamin B12 levels. The mean values for seminal plasma vitamin B12 activity in lactovegetarians from normozoospermic, oligozoospermic and azoospermic groups are significantly lower than the corresponding mean values observed in the nonvegetarian subjects. The mean vitamin B12 content of seminal plasma in azoospermic group was distinctly lower than the mean values in normozoospermic and oligozoospermic groups. However, seminal plasma vitamin B12 values showed no correlation with the sperm content of the corresponding semen in both normozoospermic and oligozoospermic subjects. Studies on sperm morphology and on biochemical parameters revealed no significant effect of the type of diet on sperm count, sperm motility, percentage abnormal sperms, seminal plasma total proteins, albumin, fructose, citric acid, acid and alkaline phosphatase activity in normozoospermic group.
饮食习惯对精液中维生素B12水平有显著影响。来自正常精子症、少精子症和无精子症组的乳素食者精液中维生素B12活性的平均值显著低于非素食者的相应平均值。无精子症组精液中维生素B12的平均含量明显低于正常精子症和少精子症组的平均值。然而，在正常精子症和少精子症受试者中，精液中维生素B12值与相应精液中的精子含量均无相关性。对精子形态和生化参数的研究表明，在正常精子症组中，饮食类型对精子数量、精子活力、异常精子百分比、精液总蛋白、白蛋白、果糖、柠檬酸、酸性和碱性磷酸酶活性均无显著影响。
