Does the Bank Ship Donor Specimens in Liquid Nitrogen Dry Shippers?

The best way to ship sperm is in liquid nitrogen vapor tank that is generally called a “dry shipper.” Dry ice is an option but it is not the preferred method because it does not completely arrest cell metabolism and will reduce the life expectancy of frozen sperm.

Sperm will stay viable in a nitrogen tank for at least seven days, even longer if the tank is fully charged.  Most experts discourage using shipping tanks for storage and recommend transfer to a monitored liquid nitrogen storage tank designed for storage.
