Products already available include oviductal and uterine fluids coming from healthy animals with all the sanitary certificates and classified according to the phase of the estrous cycle when they were collected (Carrasco et al., 2008; Reproduction 136: 833-842).

The fluids have been processed in our laboratories under strict biosafety conditions and after purification and lyophilization, their biological activity has been assessed. The test used for biological activity is the Zona Pelucida digestion time (Coy et al., 2008 Proc Nat Acad Sci USA (PNAS) 105: 15809-15814).
