On the other hand, husbands were more positive and less negative when discussing a marital problem and better social support givers when both partners had lower testosterone levels.
The Penn State team published their findings in a paper, "Gender Moderates the Relationship Between Testosterone and Marital Interaction", in the March issue of the Journal of Family Psychology. The authors are Cohan; Dr. Alan Booth, distinguished professor of sociology, human development, and demography; and Dr. Douglas A.
