Distribution of vitamin D between groups having “normal” and “altered sperm parameter/s.” (A) Box plot of median 25 and 75th percentiles showed dissimilar distribution of vitamin D between normal and altered sperm parameters. (B) Comparison of Vitamin D among fertile and infertile groups having “normal” and “altered sperm parameter/s.” Normal sperm parameters = total sperm count > 39 milion sperm per ejaculate, motility > 40%, and normal morphology ≥ 4%. Aitered sperm parameter = total sperm count < 39 million sperm per ejaculate, motility < 40% and normal morphology < 4% (at least one parameter is altered).
