Introduction: Women have high anxiety and depression incidence compared to men. In the present study, gender-related differences in correlations among BMI, salivary testosterone and cortisol and depression and alexithymia scores in university students.

Methods: A total of 88 Nigerian university students were involved in the study. Participants were 20 men and 68 women who were 17-25 years of age. Salivary assay of cortisol and testosterone were done using Enzyme-linked Immunosorbent Assay Kits. The Self-Reporting Questionnaire (SRQ) 20 adapted from WHO was used to screen for depression. Toronto Alexithymia Scale was used to assess the points associated with alexithymia.

Results: In the present study, there was a significant negative correlation between testosterone and depression in only men, but not in the total sample and women. There were significant positive correlations between depression and alexithymia scores in the total sample and women, but not in men.

Discussion: The gender difference in the relation of salivary testosterone with depression showed again that gender is a very important factor in behavioral studies including depression. It can be stated that testosterone can be an important hormonal factor to prevent or decrease depression or depressive thoughts in men but not in women. The positive correlations between depression and alexithymia scores suggest that high depression in female university students is related to social and environmental factors, but not low testosterone.

Conclusion: These results suggest that high depression in female healthy university students is may be due to social, cultural, and ecological factors, but not hormonal (cortisol and testosterone) factors.
