Caffeine affects women’s fertility. Is this true? Many studies found that consumption of even moderate coffee or other drinks containing caffeine can affect fertility in women, making it quite difficult possibility of getting pregnant. The truth is that nobody can argue with certainty that caffeinated drinks reduce your chances of conception.
In 1993 – has carried out a study comparing a group of women consuming coffee with another in which women did not drink coffee. Results showed that women who consumed less than the amount indicated as moderate (3 cups of coffee a day means moderately or 300 mg) reduced their chances of conceiving by up to 27%.
Even moderate consumption of caffeine has a negative effect on fertility. Therefore, women who consumed 1-2 cups of coffee daily reduced their chances of getting pregnant by up to 10%.
1998 – another study in which 430 couples were monitored for 3 years showed that the effects of caffeine are not that strong. Women who consumed 300 – 700 mg caffeine decreased by only 12% chances of getting pregnant. Subjects who exceeded 700 mg caffeine / day shows 37% less likely to conceive a child. Thus, experts have assumed that consumption below 300 mg of caffeine per day is almost harmless, since most studies have found significant changes in the level of caffeine.
Typically, these studies on lifestyle and fertility are often criticized for not taking into account all factors associated. Harvard University researchers say there is no conclusive proof that caffeinated beverages reduces the chances of conception. For example, another field research showed that caffeine does not affect fertility more than does tobacco (caffeine is metabolized faster by smokers).
Thus, what to believe? Perhaps it is best to rely on our own. If several months trying unsuccessfully to get pregnant and have already given up alcohol and tobacco, maybe it would be good to limit caffeine consumption (coffee, juices, chocolate) to less than 300 mg / day.
Caffeine affects male fertility?
Numerous studies have been conducted in the laboratory by mixing caffeine with sperm samples, but in real life effects of caffeine might be quite different and results will not be very accurate.
Scientific studies show that more than 2 cups of coffee a day appears to have adverse effects on fertility of women (he needs more time to get pregnant), but increases sperm motility and viability.
Approximately 75% of caffeine intake is taken by drinking coffee, tea 15% and 10% of juice and 2% chocolate.
