comparative morphological study of the accessory sex glands of immature and mature local breed donkey (Equus asinus)

Abstract

Eight samples of accessory sex glands of donkey were used to compare between the immature and mature donkey. The morphological parameters were involved position, relation, shape, length, width, and weight of each gland. The results of in immature and mature donkey the ampulla of ductus deferens were spindle shape strcture of ends part of ductus deferens, located dorsaly to the urinary bladder and opened into ejaculatory duct, in immature measured 1.85±0.04cm, 3.81±0.18mm and 0.96±0.02g and in mature measured 7.57±0.01cm,5.67±0.21mm, and 6.87±0.02g in lenghth, width and weight respectively. Vesicular gland of immature donkey was small size located laterally to the ejaculatory duct and cranillay to the prostate gland, while in mature was larger elongated gland extended more laterlly to the body of urinary bladder, in immature measured 2.13±0.03cm, 3.96±0.08mm, 1.28±0.08g and in mature donkey measured 7.97±0.09 cm, 5.76±0.30 mm, 7.53±0.10g in length, width and weight respectively. Prostate of immature was dark brown in color, small bilobed gland, located caudally to the vesicular gland and laterally to the pelvic urthera, while in mature donkey was very dark brown, and large bilobed gland, it was measured 1.76±0.19cm, 3.51±0.20mm, 3.17±0.10g and in mature measured 2.90±0.01cm, 7.88±0.26mm and 6.40±0.20g in length, width and weight respectively.
