Note in both sexes modest co-localization of CB+ neurons with ERβ and AR as well as the lack of associations of these cells with ERα. Data were expressed as mean ± standard deviation (SD). As CB+ neurons almost never co-express ERα, only the counts concerning relationships of CB+ neurons with ERβ or AR were statistically evaluated by the two-tailed t test (* p ≤ 0.05, ** p ≤ 0.01 and *** p ≤ 0.001)
