The reference values for seminal parameters were based on the WHO laboratory manual for the examination and processing of human semen [7]. ‡: Unpaired t-test results; *: statistically significant (P-value < 0.05). Bolded values indicate statistical significance. The control group initially consisted of 75 samples, but one sample was excluded prior to the remaining experiments.
