Developmental Changes of Bull (Bos taurus) Genitalia as Evaluated by Caliper and Ultrasonography

Abstract: The objective of the present study is to follow the growth of the testes and the pelvic genitalia in cattle bulls, using ultrasonographic examination and measurements of external genitalia by caliper. Six Friesian bulls were examined periodically from 3 to 24 months of age with 3-month interval. Scrotum circumference (SC) and length were measured by tape. Testicular length, width and depth were measured by caliper. Scrotal contents including testes and epididymis, and the pelvic genitalia including bulbourethr… Show more

“…In addition, the difference between MTW and MTD indicating a normal testicular function showed the testes not to be spheroid either morphometrically or functionally. Moreover, a recent study showed that the testicular width of bulls as measured using a caliper correlates with that by US, and the width by both methods reflects developmental changes 24 . These studies show that the testicular length, width, and depth obtained using calipers could be as useful for estimating testicular function as the three ultrasonographic dimensions.…”

“…1988; Chandolia et al. 1997; Abdel‐Razek and Ali 2005; Gnemmi and Lefebvre 2009, 2010). According to those reports, vesicular glands, ampulla, body of the prostate, bulbourethral glands and the disseminate portion of the prostate (within the pelvic urethra) were readily detected.…”

“…From the morphometrical aspect, Abdel-Razek and Ali 18 were measured the length of the 2 years old bull's bulbourethral glands and they found 1.2-2.1 cm long, however we found 3.1 cm long on the 2.5-3 years old bulls bulbourethral glands.…”
