| Table 1. Semen analysis results comparing samples collected after abstinence periods of 4 hours and 2-7 days. Liquefaction time, semen volume, and motility parameters were analyzed using a paired Student’s t-test, with results expressed as mean ± standard deviation (95% confidence interval). Sperm concentration, total sperm count, normal sperm morphology, and round cell concentration were assessed using the Wilcoxon signed-ranks test and are presented as medians with interquartile ranges (IQR: first quartile [Q1] to third quartile [Q3]). | |||
