TYB (test yolk buffer) Refrigeration Medium TYB with Gentamicin is ideal for short term sperm storage to preserve sperm for up to 4 days. With an easy one-step process of simply thawing the media and adding media at a 1:1 ratio with the sperm sample, it is quicker and easier than sperm cryopreservation. Refrigeration Medium TYB with Gentamicin contains TEST-yolk buffer as the protecting agent, and the glycerol-free formulation avoids the potentially damaging effects from penetrating cryoprotectants.  This product has been CE marked and FDA-cleared for short term sperm storage.

• Contains
– 20% egg yolk – from USDA certified Specific Pathogen Free (Virus Free) laying flocks, heat inactivated at 56° C for 30 minutes
– 10µg/mL Gentamicin Sulfate

The reusable ice packs need to be frozen, and we suggest that donor sperm be refrigerated for about 30 minutes, prior to shipping.  The insulated box is to minimize the chance of sperm thawing and to keep them viable for insemination.  To maximize these chances, we HIGHLY recommend overnight shipping or fastest courier service to insemination location for immediate processing. FedEx offers same day delivery in most locations.
