Can stress affect a woman’s ability to become pregnant? A new study says it may.
Over four years, 401 women who were stopping contraception and trying to have a baby underwent saliva testing for two stress-related substances: the enzyme alpha-amylase, and the hormone cortisol. The women provided a saliva sample upon enrollment in the study, and then another at their first observed menstrual period, so that comparisons between the women could be made from the same starting point.
