Comparisons of 22 trans men–22 cis female and 22 male controls are displayed at P_FWE < 0.15, and a minimal cluster size of k ≥ 100 voxels; comparisons between 22 cis male and 22 cis female controls are displayed at P_FWE < 0.05, cluster thresholded at t = 2.3, and a minimal cluster size of k ≥ 100 voxels.
