<div>Data from 583 Nelore bulls, aging from two and three years old, raised under pasture condition, were used to study andrologic traits (physical aspects: motility and vigor; and morphologic: major and total defects of the semen) and testicular measurements (scrotal circumference - SC and testicular volume - TVOL) to establish a profile of andrologic classification for fertility (BSE). The animals were divided in two groups: young bulls (N = 345), with ages from 18 to 30 months (2 years old), and adult (N = 238), with ages from 31 to 42 months (3 years old). Differences were observed (p < 0.05) for body weight, SC, physical and morphologic characteristics of the semen and TVOL in the two year olds with BSE above and below 60 poin...
