Background: Testosterone plays a crucial role in regulating sexual behavior among non‐human primates, working primarily by increasing copulatory behavior and sexual motivation. In this study, we analyzed fecal testosterone levels in five adult male Tibetan macaques (Macaca thibetana) living freely in the Huangshan National Reserve in Anhui Province. The aim was to investigate the relationships between fecal testosterone levels and sexually motivated behaviors. Methods: We collected a total of 426 fecal samples and observed approximately 453 h of focal sampling behavioral data. Sexually motivated behaviors were categorized as sexual chase, grimace, and sexual‐inspection. Results: The results showed a positive correlation between sexually motivated behaviors and copulatory behavior. Furthermore, all the three sexually motivated behaviors, including sexual chase, grimace, and sexual‐inspection, were positively correlated with fecal testosterone levels. Conclusion: Our results demonstrated positive correlations between sexually motivated behaviors and fecal testosterone in free‐ranging Tibetan macaques. [ABSTRACT FROM AUTHOR]
