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.
