The SBS CryoSystem consists of a range of freezing extenderswhich are paired with complementary freezing protocols. The SBS CryoSystem allows the clinician to identify the best freezing extender for each individual stallion.

Spectrum extenders are used to freeze stallion semen at SBS labs worldwide. Horse breeders have trusted in the expertise of SBS for decades and veterinarians recognize and appreciate SBS labs as a source of high-quality frozen semen.

Spectrum extenders feature various cryoprotectants and specific egg yolk or milk content that combine to protect sperm cells from damage caused by freezing, and protect the fertilizing ability of the semen after thawing.
