| Table 2. Effect of 20% PRGF on sperm parameters in fresh samples. Comparison of the samples 15, 30 and 45 minutes after PRGF administration with an aliquot immediately before PRGF administration and with another without PRGF 45 minutes later. Values are expressed as mean and standard deviation (SD). MD= Mean of the differences between pairs. | ||||||||
