In this study the correlation between seminal plasma protein profile and the sperm motility and sperm viability in rabbits submitted to treatment with an expression vector containing EPO gene and with human recombinant EPO was evaluated. In rabbits submitted to treatment with EPO expression vector, two protein bands were associated to sperm motility - 48kDa associated to low motility (P<0.05) and 18kDa to high motility (P<0.05) - and this protein band was also associated to high sperm viability (P<0.05). In rabbits submitted to treatment with human recombinant EPO, a protein factor, 63kDa, was associated to high sperm motility (P<0.05) while two protein factors, 26 and 40kDa, were associated to high sperm viability (P<0.05). These results suggest that gene doping leads to changes in rabbit seminal plasma protein, altering sperm motility and sperm viability.
