  • Descrição: Environmental temperatures may influence the temperature inside commercial transport boxes during semen shipment and thereby storage conditions of diluted dog semen. To evaluate the temperature changes inside boxes and their influence on sperm quality, split semen samples (n=8) were placed in Neopor boxes® exposed for 48h to room temperature (RT) (Box 1), 40°C for 6h and then kept at RT (Box 2) or 40°C (Box 3). A fourth subsample was kept at 4–5°C in a refrigerator (control). Inside Box 1 temperature initially decreased to <3°C before it stabilized at 7–8°C, while in Box 2 no decrease occurred and temperature was at 7–8°C for 48h. Temperature inside Box 3 was at 14–15°C for 24h and, thereafter, increased to 36.1°C. Analysis of sperm motility (CASA) and viability (PI and FITC-PNA) after 24 and 48h revealed marked sensitivity of dog spermatozoa to temperature fluctuations (Box 1). A constant storage temperature of 7–8°C (Box 2) provided the most desirable semen quality in terms of motility, viability, as well as osmotic resistance when samples were stored for 48h. Furthermore, results indicate that during 24h preservation a storage temperature of 14–16°C may provide optimum conditions for maintenance of sperm viability and function. An increase of the inside temperature to >30°C (Box 3) resulted in an almost complete loss in sperm integrity. In conclusion, results suggest a revision of current recommendations for storage temperature of diluted dog semen. Boxes for semen transport should be prepared depending on the expected environmental temperatures.
