Obese Couples Struggle More with Infertility
According to a team of researchers from the National Institutes of Health (NIH), couples in which both partners are obese have more difficulty conceiving a child than couples who are within a normal weight range or couples in which just one partner is overweight. Previous studies have shown that women who are under- or overweight experience higher rates of infertility, but this new research suggests the effects of weight on a couple’s ability to conceive is greater when both partners are overweight.
The study showed that obese couples are about 50 percent less likely to conceive in each cycle than average-weight couples. Couples in which both partners had a BMI—body mass index—of 35 or higher (BMI over 30 is considered obese) were 60 percent less likely to conceive.
Researchers did not determine a cause/effect relationship between obesity and infertility. Obesity increases inflammation and may affect hormones in the body that play a role in conception.
