Delivery of Donor Sperm

Donor sperm is shipped to all destinations around the world. Shipments are either sent in a dry ice container or in a nitrogen tank. Donor sperm can also be collected in person from Cryos.

Dry Ice - CO2

The sperm straws are placed in an insulated dry ice container. Dry ice lasts for approx. 3 days before thawing, depending on the temperature of the surrounding environment. We therefore recommend only using dry ice shipments Monday to Wednesday to ensure that the shipment reaches its destination before the weekend.

Following delivery, it is important that the sperm straws are in constant contact with the dry ice until thawing/use and that both the inner box and the outer box are closed. Be advised that dry ice shipments cannot be shipped to New York State.

The dry ice container is non-returnable.

Nitrogen – LN2

Also called liquid nitrogen (-196°C). The sperm straws are placed in a jar in a nitrogen tank, which is placed inside a transport box. A nitrogen tank will keep sperm straws frozen for seven days. For an additional charge, you can order a large nitrogen tank that will keep sperm straws frozen for 12 days. When ordering, indicate in the text field if you want a large nitrogen tank. We cannot guarantee that a large nitrogen tank will be available on the day of shipment. Donor sperm should be stored in the nitrogen tank until use, or be moved to another nitrogen tank at a clinic.

Cryos has two sizes of liquid nitrogen dry shipper tanks (small and large). Small tanks will keep the straws frozen for up to 7 days.  Large tanks will keep the straws frozen for up to 12 days. Small and large liquid nitrogen dry shipper tanks are used for shipments within the United States. Internationally, Cryos only uses large liquid nitrogen dry shipper tanks.
