Role of seminal plasma in damage to turkey spermatozoa during in vitro storage

These results show that seminal plasma is deleterious to storage of turkey spermatozoa at 4 °C and is involved in phospholipid metabolism of spermatozoa. Lipid peroxidation could be responsible for the acceleration of the degradation of sperm phospholipids during storage at 20 °C. However, lipid peroxidation seems not to be active at 4 °C. In this case, we suggest that phospholipase activation may contribute to sperm degradation, especially in the presence of seminal plasma.
