TYB (test yolk buffer) Refrigeration Medium TYB  is ideal for short term sperm storage to preserve sperm for up to 3 to 4 days. With an easy one step process of simply thawing the media and adding media int a 1:1 ratio with the sperm sample, it is quicker and easier than sperm cryopreservation. Refrigeration Medium TYB  contains yolk buffer as the protecting agent, and the glycerol-free formulation avoids the potentially damaging effects from penetrating cryoprotectants. This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.

Sperm should be washed prior to use.

• Contains
– egg yolk

The reusable ice pack needs to be frozen, and we suggest that sperm be refrigerated for about 30 minutes, prior to shipping.  The insulated box is to keep the sperm cold 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.

We only ship TYB Monday thru Thursday to insure the TYB does not get warm.

TYB should be shipped with 1 day shipping to maintain viability. If customer opts for a longer shipping method, we will not guarantee viability and will be held harmless of product outcome.
Next day shipping will be required at checkout or we may cancel the order at our discretion.
