HIPPEX CRYO is a new liquid medium to freeze stallion sperm cells. The liquid medium has several unique characteristics.

• The first unique feature is that no egg yolk is used as a cryoprotectant.
• The second unique feature is the possibility to sell the product HIPPEX CRYO as a powder.
• A third unique feature is that HIPPEX CRYO has an equal or better performance than a standard egg yolk freezing medium. 

It is expected that the fertility after freezing/thawing with HIPPEX CRYO is higher than with the use of an egg yolk containing medium because there is a strong correlation between progressive motility and pregnancy rate. This was also found earlier for HIPPEX, which is used as a medium to keep semen chilled. 

The product is delivered with 2 bottles - one containing the HIPPEX CRYO in a powder format (to dilute) and one containing the glycerol (2,4%)
