Maturational changes in motility, acrosomal proteolytic activity, and penetrability of the inner perivitelline layer of fowl sperm, during their passage through the male genital tract
چکیده انگلیسی
The objective was to examine, in vitro, the motility, acrosomal proteolytic activity (APA), and penetrating ability of fowl sperm recovered from the testis and epididymis, as well as the proximal, middle, and distal vas deferens, to assess the potential fertilizing ability of sperm as a function of maturation. A motile sperm separation technique was used to estimate sperm motility with Accudenz, a gelatin slide technique was used to measure the diameter of the halo around the acrosome of individual sperm as an indication of APA, and a sperm-inner perivitelline layer (IPL) interaction assay was done to estimate the number of hole formations as an indication of sperm penetration into the IPL. Sperm in the testis exhibited the least motility, produced the smallest halos, and created the least number of holes per 0.25 mm2. Motility, diameter of the halo, and number of holes increased gradually (P < 0.05) from the epididymis to the distal vas deferens and were markedly different (P < 0.05) between testicular and deferent duct sperm. Based on these in vitro experimental findings, we inferred that fowl sperm undergo a gradual process of maturational changes in motility, APA, and penetrability as a means of acquiring potential fertility during their passage throughout the male genital tract.
