Study Results from University of Teramo in the Area of Veterinary Science Reported (Reviving Vacuum-dried Encapsulated Ram Spermatozoa Via Icsi After 2 Years of Storage).

A study conducted at the University of Teramo in Italy has explored the use of freeze-drying techniques to preserve mammalian spermatozoa without the need for liquid nitrogen. While previous research has focused on laboratory mice, this study aimed to gather information on large animals that could also benefit from this storage method. The researchers found that vacuum-drying encapsulation (VDE) resulted in better structural stability, lipid composition, and DNA integrity in ram spermatozoa compared to canonical lyophilization (FD). The study highlights the importance of considering dehydration-related changes in sperm polyunsaturated fatty acids and DNA alterations in large mammals, as they play a crucial role in embryonic development.
