Women who struggle to conceive appear to have an increased risk of stroke, heart attack and angina, according to two new studies published in the European Journal of Epidemiology and Fertility and Sterility. Researchers at the Norwegian Institute of Public Health studied women who had tried to get pregnant for at least a year before they succeeded. They found that the women who experienced reduced fertility had a 20 percent higher risk of stroke and heart attack over the next 14 years. Looking at another group of women with reduced fertility, they had a 14 percent higher risk of all cardiovascular disease. These studies do not reveal the cause for the increased risk. The researchers speculate that childlessness could be a marker for an increased risk of other health problems. It’s also possible that the stress of trying to get pregnant may affect the health of your heart.
