Moderate Iodine Deficiency May Reduce Fertility
Previous research has indicated that mild-to-moderate iodine deficiency is becoming more common among women of childbearing age.
In a new study, women with moderate-to-severe iodine deficiency were 46% less likely to become pregnant during each menstrual cycle compared to women who had sufficient iodine concentrations. The study published in Human Reproduction was the first to look at the connection between mild-to-moderate iodine deficiency and fertility.
Iodine is an essential nutrient that regulates metabolism, bone growth, and brain development in children. Iodine deficiency is becoming more common due to the preference for sea salt or kosher salt instead of iodized table salt, and is more common among vegetarians and vegans.
The researchers suggested that public health officials in countries where iodine deficiency is common should consider programs to increase iodine intake in women of child bearing age.
