Ogawa observed damage to blood capillaries in the testes, leading to testicular hemorrhage, loss of continuity of germinal epithelium and interstitial fibrosis in mice with a high dose of cadmium chloride (10 mg/kg).
In the present study a significant increase in the thickness of the germinal epithelium was observed that likely cause of persistent follicles and subsequent ovulation and ovarian volume is another reason is the increase in size of the ovary and Sekoulareh and creates congestion and cortical vasculature [28].
Six-too-old animals showed initial development of germinal epithelium, whereas at 12 mo of age (SL, 30.

Neither the germinal epithelium nor sex-cord stromal elements (Sertoli and Leydig cells) of normal testicular tissues (chicken) revealed any immunoreactivity to any of the markers used to evaluate the mynah tissue.
In seminiferous duct the germinal epithelium has less density and in some pipes the spermatogenesis cells series are completely condensed, their number is decreased and the most remaining cells are spermatogony cells.
Three stages were present: (1) Regression, the germinal epithelium was reduced to 1-3 cell layers in thickness and consists of spermatogonia and Sertoli cells; (2) Recrudescence, a proliferation of germ cells for the next period of sperm formation was underway.
Three stages were present: (1) Regression: germinal epithelium of the seminiferous tubules is 1-2 layers thick and is composed mainly of spermatogonia with occasional Sertoli cells; (2) Recrudescence: there is an increase of cellularity in the seminiferous tubules due to a proliferation of germ cells; primary spermatocytes predominate.
In the late vitellogenic oocyte, exogenous substances, namely, glycogen particles and lipid granular substances appeared in the germinal epithelium passed into the ooplasm through the microvilli of the vitelline envelope.
