Ten healthy male (boar) of large white pigs aged between 6.0 and 18.0 months, were used for this study. Spermiogram and morphological characteristics were studied in testes and in the different parts of the epididymis of the boar. The objective was to study the changes that occur in testes and epididymis during epididymal transit. Progressive motile spermatozoa were first observed in the testes (6-10%) in the caput (20-30%), corpus (40-50%) and highest at the caudal epididymis (85%). Cytoplasmic droplets were lost as the spermatozoa moved up the epididymis. The caput epididymis had a value of 20.05% of abnormal sperm cell, which is different significantly (p%26lt;0.5) from 15 - 80 % of the caudal epididymis. The total abnormal sperm cells in corpus are also higher than in the caudal epididymis Percentage motility was 0.6 ㊣ 2.0 % in the testis, which was lower (P%26lt; 0.5) than in caput with 23.0 ㊣ 5.0%. This motility increases from caput to caudal epididymis. The caput epididymis also had 0.20% of spermatozoa with small head, which differed significantly (p%26lt;0.05) from corpus (0.05%) and the caudal (0.00%). The testicular and epididymal parameters were positively correlated (weight of testis and epididymis; weight of testis, scrotal circumference, testicular circumference, weight of epididymis and weight of testis (p%26lt;0.05), except the correlation values between testes and epididymis circumference (TEC) and other parameters (p%26lt;0.01) Para la investigaci車n se utilizaron 10 verracos de cerdos blancos de gran tama o, con edades entre 6 y 18 meses. Se realiz車 el espermiograma y se observaron las caracter赤sticas morfol車gicas, en los test赤culos y en las diferentes partes del epid赤dimo. El objetivo fue estudiar los cambios que ocurren en los espermatozoides a nivel de los test赤culos y del epid赤dimo durante el tr芍nsito epididimal. Los espermatozoides m車tiles progresivos se observaron primero en test赤culos (6-10%), en la cabeza (20-30%), cuerpo (40-50%) y en la cola de epid赤dimo (85%). Pierden gotas citopl芍smicas, en la medida en que los espermatozoides se trasladan ascendiendo hasta el epid赤dimo. La cabeza del epid赤dimo presenta un valor de 20,05% de c谷lulas anormales de espermatozoides, lo que es significativamente muy diferente (p%26lt;0.5) de 15-80% en la cola del epid赤dimo. El total de espermatozoides anormales en el cuerpo del epid赤dimo, es tambi谷n m芍s alto que en la cola del epid赤dimo. El porcentaje de motilidad fue de 0,6 ㊣ 2,0% en el test赤culo, el cual era m芍s bajo (p%26lt; 0.5) que en la cabeza del epid赤dimo, con 23.0 5 0%. Esta motilidad aumenta desde la cabeza a la cola d
