Histological findings and seasonal distribution of different germ cells in the testicles of freshwater needle fish, Xenentodon cancila (Hamilton)Author(s):
P. Chakrabarti, A. S. BanerjeeAbstract:
The cytomorphological changes occurred in the testicles of Xenentodon cancila (Hamilton) were elaborated during different reproductive phases. The testicular lobules were synchronously arranged with various stages of germ cells such as spermatogonia, primary and secondary spermatocytes, spermatids and spermatozoa. The seminiferous tubules were made up of spermatogenic cells located within cysts during growth phase. However, the seminiferous tubules were dominated by cysts of spermatocytes, spermatids and spermatozoa during maturation phase. Pubertal seminiferous tubules were packed with spermatids and spermatozoa. In the post spawning phase the tubules contained remnants of spermatozoa and spermatogonial cysts. The Leydig cells were close to the blood vessels in the interstitium. The sequential proliferative pattern of various germ cells in the tubular spaces was correlated withrngonadosomatic index during different reproductive phases.Pages: 74-80 | 808 Views 7 DownloadsDownload Full Article:
