Behavioral assessment of anxiety in rats with endometriosis and sham controls. A, There was no difference in locomotor activity for the rats with endometriosis or sham controls in the open field test. B, Rats belonging to the endo-enrichment group (EE) spent significantly more time in the center of the arena compared to the endo-no enrichment (NE) group suggesting decreased anxiety. C, In the zero maze, rats belonging to the endo-EE group had decreased locomotor activity compared to the sham and the endo-NE groups. D, Despite the difference in locomotor activity, there was no difference between groups in the percentage of time spent in the open arms of the zero maze. In this and subsequent graphs, bars represent average ± standard error of the mean (SEM). * P < .05.
