Epidemiological studies suggest a relationship between vitamin D deficiency and erectile dysfunction (ED) but its causal relationship and the mechanism involved are unclear. Here we demonstrate that isolated corpora cavernosa (CC) from human donors with low vitamin D levels show reduced NO-dependent erectile function. This ED is also reproduced in vitamin D deficient rats and vitamin D receptor knockout mice in vivo and ex vivo and is associated with penile fibrosis. Vitamin D deficiency also blunts the response of CC to the phosphodiesterase 5 inhibitor sildenafil. CC from deficient rats show increased superoxide and their impaired erectile function is restored by superoxide scavengers. These results suggest that vitamin D deficiency induces ED via increased superoxide production.
