However, one factor that hinders the ability to monitor this species in the wild is the difficulty to measure relevant physiological parameters which quantify the survival status in conservation research. In this study, we employed a non-invasive sampling method and immunochemical assays to determine if measurement of fecal steroid hormones is a viable option in monitoring the sex ratios and stress levels of a giant panda population. The results indicate that 1) the yearly concentration of fecal testosterone is a possible biomarker for distinguishing gender, and 2) invasive methods of artificial insemination and semen collection as well as
