This article states that chewing gum was used, but does not indicate what was in the chewing gum, whether or not the two groups received the same chewing gum, or if chewing gum in general has any impact on saliva hormone test results.
Would the author(s) please provide more detail regarding the methodology of this research?
Thank you,
Dr. Julien Arbor

1) We used sugar-free Trident original chewing gum.
2) All participants received the same gum.
3) Past studies have shown that sugar-free gum does not have an impact on testosterone levels measured in saliva (Dabbs, 1991). For a detailed description of the methodology used in the assessment of hormones in saliva see Schultheiss and Stanton (2009).
