To those looking to conceive, one American study believes you should probably lay off the soft drink. Save that for your insane pregnant cravings.
If you or someone you know is trying to get up the duff, then backing away from the soft drinks may increase your chances of conception, according to recent research findings.
Researchers at Boston University School of Public Health have identified links between lowered fertility and the consumption of sugar-sweetened drinks. This American study, published in Epidemiology, found that among couples trying to conceive, those who consumed one or more sugar-sweetened drinks per day (by either partner) decreased their likelihood of successful conception by an average of 20 percent.
The study involved 3,828 women in the USA and Canada and 1,045 of their male partners, all of whom were aged between 21 and 45 years of age. An extensive questionnaire into their medical history, diet and other lifestyle factors was undertaken, with follow-up surveys every two months for up to 12 months, or until they became pregnant.
After taking into account other elements affecting fertility, such as smoking, diet, caffeine and alcohol consumption, and obesity, the researchers found that both female and male intake of sugar-sweetened beverages was associated with reduced fecundability (i.e., the average monthly probability of conception).
The findings suggest that consumption of one soft drink per day can reduce fecundability by 33 percent in males, and by 25 percent in females. What’s more, energy drinks were found to be linked to even higher decreases in fecundability, although these findings were based on a small sample size, so may require more indepth investigation to be conclusive.
Interestingly, there was no definitive link found between fertility and the consumption of fruit juices or diet sodas.
