| Table 3. Effect of 20% PRGF on sperm parameters in thawed samples. Comparison of the samples with 20% PRGF 15, 30 and 45 minutes after thawing with a control aliquot without PRGF 45 minutes. Values are expressed as mean and standard deviation (SD). MD= Mean of the differences between pairs. | |||||||
