The bone structural parameters (BV/TV, TbTh, TbN and TbSp) were evaluated using bone histomorphometry technique. In the first part of the study, there were no significant differences in the BV/TV, TbTh, TbN, and TbSp between the NC and EL group (Figures 5 , 6 , 7 , and 8 ). While for the second part of the study, orchidectomy has resulted in significantly lower BV/TV of the OrxC group compared to the Sham group. When the orchidectomised rats were given testosterone (Orx + T group), the BV/TV was restored equal to that of the Sham group. However, when the orchidectomised rats were supplemented with EL (Orx + EL), the BV/TV remained unchanged and was significantly lower than the Orx + T group (Figure 9 ).
