Table 1 Comparison of sociodemographic characteristics and semen parameters of candidate sperm donors before and after the COVID-19 pandemic Age and abstinence time were presented as mean (SD) for the results. Semen parameters were presented as median (IQR) for the results. Differences between age and abstinence time were compared using Student’s t-test. Differences between semen parameters were compared using Mann-Whitney U test. SD standard deviation, IQR interquartile range
