To perform biometric analysis of Egyptian indigenous donkeys´ reproductive organs using
ultrasound and correlate the findings with serum hormonal levels, 25 apparent healthy jacks aged between 2-12
years were used. The ultrasonographic measurements of internal (bulbourethral, prostate, vesicular glands,
colliculus seminalis and pelvic urethra) as well as external (testes, epididymis and scrotum) organs were
measured over three-weeks period for each animal and for each structure. The scrotal length, width and
thickness were measured with a caliper (mm). An impact of testicular size in normal donkeys was noticed on the
measures (length and width) of the prostate gland, vesicular gland, ampulla ductus deference and colliculus
seminalis. Testes measures were highly (p 100 mm3. Moreover, there was a close positive association between
testicular volume and scrotal thickness (r=0.939, p |
