Abstract

Objective: The relationship between fertilization rates and 1,25-dihydroxyvitamin D (1,25(OH) 2 D 3 ), 25-hydroxyvitamin D2 (25(OH)D 2 ), 25-hydroxyvitamin D3 (25(OH)D 3 ), 24,25-dihydroxyvitamin D (24,25(OH) 2 D 3 ), and 25-hydroxy-3epi-Vitamin D3 (3epi25(OH)D 3 ) concentrations in age and weight matched women with and without PCOS was studied. Methods: Fifty nine non-obese women, 29 with PCOS, and 30 non-PCOS undergoing IVF, matched for age and weight were included. Serum vitamin D metabolites were taken the menstrual cycle prior to commencing controlled ovarian hyperstimulation. Results: Vitamin D metabolites did not differ between PCOS and controls; however, 25(OH)D 3 correlated with embryo fertilization rates in PCOS patients alone (p = 0.03). For all subjects, 3epi25(OH)D 3 correlated with fertilization rate (p < 0.04) and negatively with HOMA-IR (p < 0.02); 25(OH)D 2 correlated with cleavage rate, G3D3 and blastocyst (p < 0.05; p < 0.009; p < 0.002, respectively). 24,25(OH) 2 D 3 correlated with AMH, antral follicle count, eggs retrieved and top quality embryos (G3D3) (p < 0.03; p < 0.003; p < 0.009; p < 0.002, respectively), and negatively with HOMA-IR (p < 0.01). 1,25(OH) 2 D 3 did not correlate with any of the metabolic or embryo parameters. In slim PCOS, 25(OH)D 3 correlated with increased fertilization rates in PCOS, but other vitamin D parameters did not differ to matched controls. Conclusion: 3epi25(OH)D 3 , 25(OH)D 2 , and 24,25(OH) 2 D 3 , but not 1,25(OH) 2 D 3 , were associated with embryo parameters suggesting that vitamin D metabolites other than 1,25(OH) 2 D 3 are important in fertility.
