Boston University researchers surveyed nearly 4,000 women and more than 1,000 of their male partners, looking at everyone’s medical history, lifestyle factors and diet. The data revealed that drinking soda was linked to a reduction in the average monthly probability of conception for both men and women.
Women who drank at least one soda per day demonstrated a 25 percent lower monthly probability of conception, while men who drank at least one soda per day had a 33 percent lower probability of successfully conceiving with their partner.
Drinking soda is also tied to early menstruation and poor semen quality — although few studies have investigated the direct effects that soda may have on fertility.
The authors explain that given the amount of sugary drinks consumed across the U.S., their findings may have important implications for public health.
“We found positive associations,” says lead study author Elizabeth Hatch, who is a professor of epidemiology, “between intake of sugar-sweetened beverages and lower fertility, which were consistent after controlling for many other factors, including obesity, caffeine intake, alcohol, smoking, and overall diet quality.”
