摘要：

The association between time to conceive reported by 2817 fertile women who had recently had a liveborn child and consumption of coffee, tea, and "cola" drinks has been investigated. No evidence for an adverse effect of caffeine was found. For levels of consumption ranging from less than one cup of coffee per week (501 mg caffeine per month) to more than two cups of coffee per day (7000 mg per month), the average time to conceive was similar. The fecundability ratio adjusted for known risk factors for time to conceive was 1·03 (95% confidence interval 0·92-1·16) between those who consumed more than 7000 mg caffeine per month and those who consumed 500 mg or less per month. Furthermore caffeine consumption was not associated with infertility in 1818 infertile women and their primiparous controls. © 1990.
