Objective   In diabetes mellitus, vitamin D 3  deficiency affects sex hormone levels and male fertility; however, the mechanism leading to the disorder is unclear. This research was designed to investigate the mechanism of vitamin D 3  deficiency and hypogonadism in diabetic rats. Our aim was to assess serum vitamin D 3  levels and the relationship among vitamin D 3 , insulin-like growth factor-1 (IGF-1), and testicular function.Materials and Methods   Rats with streptozotocin-induced diabetes were randomly divided into four groups and treated with different doses of vitamin D 3 : no vitamin D 3 , low (0.025  μ g/kg/day), high (0.1  μ g/kg/day), and high (0.1  μ g/kg/day) with JB-1 (the insulin-like growth factor-1 receptor inhibitor group, 100  μ g/kg/day). The groups were compared with wild-type rats, which function as the control group. Various parameters such as vitamin D 3  and IGF-1 were compared between the experimental and wild-type groups, and their correlations were determined.Results   Twelve weeks of vitamin D 3  supplementation improved the testosterone levels, as shown by the increase in the level of serum IGF-1 in diabetic rats. Phosphatidylinositol-3-kinase (PI3K)/protein kinase B (AKT), which was a downstream of the signaling pathway of IGF-1, was significantly increased after vitamin D 3  treatment.Conclusions   The study shows that vitamin D 3  may promote the expression of testosterone and improve testicular function in diabetic rats by activating PI3K/AKT via IGF-1.
