Table 1. Effect of PRGF on sperm parameters. Comparison of fresh and thawed samples 30 minutes after PRGF administration (t=30’) with an aliquot immediately before PRGF administration (t0). PRGF was added at different concentrations in dilutions of 0.5:10, 1:10, 2:10 and 4:10. Values are expressed as mean and standard deviation (SD).
