A study reveals that high cortisol levels in the third trimester of pregnancy may lower IQ scores in 7-year-old boys but improve scores in girls when higher urine cortisone levels are present. This research underscores the different impacts of prenatal cortisol and cortisone exposure on male and female fetal development.
Surprisingly, cortisol levels in the blood are not associated with IQ scores in girls, but higher urine cortisone levels improved their scores. The findings highlight the important role cortisol plays in fetal development in boys and girls independently. Now, in this study, the researchers analyzed data on the cortisol and cortisone levels of 943 pregnant women during the third trimester and on the IQ tests of their 943 children aged 7 years old, from the Odense Child Cohort. They found that pregnant women carrying a boy had lower cortisol levels circulating in their blood than those women carrying a girl. In addition, boys exposed to higher cortisol levels in the womb scored lower on IQ tests at age 7.
