Vitamin D supplementation and serum AMH
At baseline, all included men were vitamin D insufficient with a mean serum 25OHD of 35 nmol/L. On day 1, the mean serum 25OHD had increased to 45 nmol/L despite no treatment received. After 150 days of intervention, men randomized to vitamin D and calcium had a significant average 93% increase in serum 25OHD from mean 46 nmol/L to 89 nmol/L, while men randomized to placebo had a non-significant average 13% increase in serum 25OHD from mean 45 nmol/L to 51 nmol/L. On day 1, the vitamin D and the placebo group had an average serum AMH of 40 pmol/L and there were no significant associations between serum 25OHD and serum AMH (Fig. The association between vitamin D and serum AMH at day 1 and after 150 days of supplementation with vitamin D + calcium.
