Structural Modification of the Black Bengal Buck (Capra hircus) Acrosome During Post-testicular Maturation of Spermatozoa Modificación Estructural del Acrosoma de la Cabra Black Bengal (Capra hircus) Durante la Maduración de los Espermatozoides

The present study was conducted to measure various biometric parameters of intact/normal acrosomes (AC) collected respectively from caput, corpus and cauda epididymis and vas deferens of Black Bengal buck. Giemsa stained acrosomes were measured after camera lucida drawings. Observations revealed dimensional characters of the acrosomal cap diminished gradually and significantly (p<0.01, p<0.05) during spermatozoa maturation phases in the different regions of the excurrent duct. Shape and size of the AC were also found to be influenced significantly (p<0.01, p<0.05) by the age and body weight of the animals. The structural modification along with decrease in the morphology of the AC reflected one of the maturational indexes of the male gametes in Black Bengal buck.
