Figure 2.

Delay time in hours to peak excretion in urinary and fecal samples of C57BL/6J mice. Peak excretion times are depicted separately for the morning (n = 16) and evening (n = 16) injection group. Mice from the morning group received the ³H-testosterone one hour after the onset of the light phase, whereas mice from the evening group received the ³H-testosterone one hour after the onset of the dark phase. Dots are outliers with values between 1.5‒3.0× interquartile range.
