A recent study from the NIH suggests that couples who have high cholesterol levels may not just be at higher risk for heart disease, they may also have a harder time getting pregnant. Couples (who were not yet considered infertile) in which both partners or even just the female partner had high cholesterol levels on average took a longer time to conceive. These findings are not so surprising since ovulation disorders such as polycystic ovarian syndrome (PCOS) are among the most common causes for infertility, and many of these patients have underlying metabolic problems that place them at risk for heart disease and diabetes. So what does this mean? It does not mean couples trying to get pregnant should rush out and go on statins to lower their cholesterol. Cholesterol is the chemical from which sex hormones such as estrogen and testosterone are made from, so these drugs could potentially be harmful to your fertility. However, healthy lifestyle changes such as moderate excercise and avoiding processed high carbohydrate foods may help both cholesterol and fertility.
