Abstract:
【Objective】 To explore the correlation between serum vitamin D level and male semen parameters and serum sex hormones. 【Methods】 A total of 56 men who received assisted reproductive treatment in our hospital during Oct.2020 and Oct.2021 were included in the infertility group, and 56 male patients with previous reproductive histories who were treated due to other diseases during the same period were enrolled as the control group. The sperm motility and concentration were assessed using a computer assisted semen analysis system (CASA). The normal sperm morphology rate was evaluated with sperm morphological staining. Sperm DNA fragmentation index (DFI) was detected with chromatin diffusion method to evaluate sperm chromatin integrity. Serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone (T) and 25-hydroxyvitamin D [25(OH)D] were detected with ELISA. The correlation between serum 25(OH)D level and semen parameters and sex hormones was analyzed. 【Results】 Serum 25(OH)D level was significantly higher in the control group than in the infertile group (P=0.002). It was positively correlated with semen parameters, including sperm motility (r=0.483, P<0.001), sperm count (r=0.216, P=0.019), and testosterone level (r=0.210, P=0.025). There was no significant correlation between serum 25(OH)D concentration and sperm morphology, LH and FSH levels. 【Conclusion】 Serum 25(OH)D is significantly correlated with and affects total sperm count, sperm motilityand serum testosterone, thus playing a role in male reproduction. The specific mechanism needs further study.
