Impactul acţiunii antioxidanţilor steroizi asupra stării morfo-funcţionale a spermatozoizilor de cocoş la crioconservare

Abstract

Steroidal glycosides possess antioxidative endogenous properties on the peroxidation processes in biological products. Therefore, steroidal glycosides could represent one of the solutions for maintaining of morphological and physiological functions of spermatozoa. The researches aimed to study the influence of the steroidal glycosides as antioxidants, on cock sperm sanogenity in the cryoconservation process. The following physiological and morfological indices of sperm were assessed: the mobility, the pathological forms and acrosome integrity of spermatozoa. The obtained results established the optimal concentration of the -Lilia-Hand Treozida Lilia in the composition of synthetic media used for cock sperm cryoconservation. The antioxidative effect of the researched steroidal glycosides was confirmed by maintaining the morphological-functional status of the spermatozoa and diminution of the gamete pathology.
