Abstract
Twenty adult common quail male obtained from Soq-Al-Shiyookh local
market .They were kept under light and feeding conditions adopted by it. The
anatomical study was appeared that the reproductive system in common quail consist
of paired testes ,efferent ducts, epididymis, vasdeference and recetaculum .The testes
are lying within the abdominal cavity and are joined to the dorsal body wall by short
connective tissue . They are paired oval-shaped structure .The average of the left
testicular size is ( 2 ± 0.04 cm3) and the average of the right testicular size is (1.85 ±
0.01 cm3).The average of the left testicular weight is (1.9 ± 0.01 gm. ) and the average
of the right testicular weight is (1.7 ± 0.01 gm.). The testes of quail are long axis is
oblique and directed dorso caudally .The epididymis is relatively large and is firmly
attached to the dorso lateral surface of the testes. The histological study was showed
that the spermatogonia are identified adjacent to the basement membrane of the
seminiferous tubules either singly or in cluster but they do not form a complete basal
layer. The primary spermatocyte are the largest cells of the spermotogenic population
. Their nuclei are notable for both their size and appearance ,being big and vesicular is
due to the presence of condensed chromatin. The secondary spermatocyte enter the
second meiotic division ,the subsequent cells formed from this division are
spermatids. Spermatocytogenesis ends when spermatids appears .The spermatids
undergo a complex process of differentiation leading to the transformation of these
spermatids into sperm . Based on changes in the acrosomes and nuclei during the
development of spermatid will give rise mature spermatozoa
