Inorganic elements, vitamin B-12 and folate may play an important role in the visual development of amblyopic children. Conclusion: Amblyopic children are significantly deficient in some inorganic elements. All of these minerals, except phosphorus, were also significantly lower in those with severe amblyopia compared to those with milder amblyopia and controls (p<0.05). The levels of phosphorus (p=0.012), selenium (p=0.002), molybdenum (p<0.001), iodine (p=0.002), chromium (p=0.022), boron (p<0.001), and beryllium (p=0.005) were all significantly lower in the amblyopia group compared to the control group. Children with severe amblyopia had lower vitamin B-12 and folate and higher body mass index. RESULTS: Linear mixed models and cubic spline curves showed positive dose-response relationships between urinary Zn and sperm concentration and total count and between urinary Mo and total sperm count [all False Discovery Rate (FDR) adjusted p-value for trend 0.05).

Multiple informant models were used to identify potential critical windows of susceptibility. Linear mixed models and cubic spline curves were used to evaluate associations between urinary essential elements and semen quality. METHODS: 1428 healthy men provided 3766 urine and 6527 semen samples, which were measured for urinary essential element concentrations and sperm quality parameters, respectively. OBJECTIVES: To investigate the associations of urinary Fe, Co, Cu, Zn, Se, Rb, Sr, and Mo concentrations with semen quality in healthy men screened as potential sperm donors and identify critical windows of susceptibility. However, their associations with human semen quality remain inconclusive. Identifying windows of susceptibility to essential elements for semen quality among 1428 healthy men screened as potential sperm donorsīACKGROUND: Essential elements such as iron (Fe), cobalt (Co), copper (Cu), zinc (Zn), selenium (Se), rubidium (Rb), strontium (Sr), and molybdenum ( Mo) are necessary for reproductive health.
