Rats in proestrus are more sensitive to colorectal distention compared with rats in metestrus/diestrus (n=12 per group). A: the threshold for eliciting a visceromotor response in proestrus rats is significantly lower than metestrus/diestrus rats. * Rank sum test p<0.05; B: The magnitude of the visceromotor response to graded intensities of distention was significantly greater at each distention pressure in rats in proestrus compared to rats in metestrus/diestrus. * Two way RM ANOVA p<0.05.
