How is frozen semen stored, and how long will it last in the tank?
Frozen semen is stored in a large liquid nitrogen holding tank at -196 degrees Celsius and is shipped in a liquid nitrogen shipping canister at -150 degrees Celsius. Many veterinarians have a liquid nitrogen holding tank at their clinic. At temperatures between -321 to -238 degrees Fahrenheit all biological processes are stopped until the semen is thawed and the sperm cells come “back to life”. Experts say that frozen semen will keep indefinitely if it is stored properly. If the frozen semen warms at all before it is thawed for insemination, it is ruined. Maintaining the proper temperature in the holding tank and the shipping canister is critical!
