This study aimed to evaluate the effect of Mauritia flexuosa oil on the structural integrity of spermcryopreserved goats. four clinically healthy goats were used. thirty-two samples were taken, with dilution inTris-egg yolk-glycerol and diluent containing vegetable oil (Mauritia flexuoxa). After cryopreservation, thesamples were thawed and evaluated for sperm plasma membrane integrity parameters of acrosome andmitochondrial activity. The percentage of cells with mitochondrial activity and acrosome integrity were higher inthe control group (P <0.05). There was no difference in the percentage of cells with membrane integrity betweenthe groups (P > 0.05). The addition of the seminal Mauritia flexuoxa thinner not kept mitochondrial activityparameters and plasma membrane integrity of sperm at levels similar to conventional thinner, but was able tomaintain the integrity of the sperm plasma membrane.(AU)
