Higher cholesterol levels may prevent or delay pregnancy, according to a new study led by the National Institute of Child Health and Human Development.
Researchers observed 501 couples enrolled in the Longitudinal Investigation of Fertility and the Environment (LIFE) study.
Couples with higher total cholesterol levels showed lower pregnancy rates or took longer to become pregnant, compared with those who had lower levels.
This research suggests that healthful lifestyles may affect conception.
