ABSTRACT
BACKGROUND:
Examining semen cryopreservation in Calomys laucha offers valuable insights for reproductive research and species conservation.OBJECTIVE:
To determine the most effective sugar for the cryopreservation of C. laucha semen. MATERIALS ANDMETHODS:
Using 36 epididymides from C. laucha, semen samples were diluted in a 3% skimmed milk medium supplemented with one of four sugars (glucose, fructose, lactose, or sucrose) at a concentration of 0.3 M. These mixtures underwent a conditioning phase at 37 degree C for 10 min, cooled to -80 degree C for another 10 min, and were subsequently stored in liquid nitrogen.RESULTS:
Upon thawing, samples treated with lactose and glucose solutions show superior sperm motility, achieving 8.2% and 10.0% respectively, in contrast to the fructose (2.0%) and sucrose (4.1%) mixtures. Furthermore, samples preserved in glucose registered the highest sperm penetration rates, reaching 44.9%.CONCLUSION:
Our findings suggest that a cryopreservation medium containing 0.3 M glucose can contribute to the safeguarding C. laucha rodent semen. https//doi.org/10.54680/fr24210110612.
