Our aim was to explore the existence of a possible relationship of sperm motility with serum 25‐hydroxyvitamin D3 (25‐OH VD) levels and with ischaemia‐modified albumin (IMA) levels in infertile Turkish men. A total of 30 men with nonobstructive azoospermia (no spermatozoa in ejaculate), 30 men with oligospermia (total progressive motile sperm count (TPMSC) <15 × 106/ml) and 33 fertile men with normospermia (with at least one child, as the control group) were enrolled in the study. The mean 25‐OH VD levels for groups 1, 2 and 3 were 9.31 ± 6.46, 19.71 ± 12.80 and 30.52 ± 12.49 respectively (p <.05). There was a statistically significant difference in serum IMA levels among the groups (479.32 ± 307.56 vs. 296.37 ± 127.27 vs. 150.04 ± 81.05, respectively; p <.05). A positive correlation between serum 25‐OH VD levels and TPMSC, and a negative correlation between TPMSC and serum IMA levels were determined. Infertile men had lower serum 25‐OH VD and higher IMA levels than fertile men, with a positive correlation between serum 25‐OH VD levels and TPMSC, and a negative correlation between TPMSC and serum IMA levels. Vitamin D supplementation may increase the sperm motility. [ABSTRACT FROM AUTHOR]
