Effect of adenosine injection for twelve weeks on testosterone concentration (ng/ml) of rabbit males (pre puberty). 

Effect of adenosine injection for twelve weeks on testosterone concentration (ng/ml) of rabbit males (post puberty) 

Cross section in the testis of male rabbit. 3A. (pre puberty) treated with of adenosine (low dose) revealing all stages of spermatogenesis. a) spermatogonia (SG) resting on basement membrane (BM), spermatocyte (SC), spermatids (sd) spermatozoa (SP), interstial space and Interstitial cells of leydig (IT) . (x 400). 3B. Cross section in the testis of rabbit male (Post-puberty) treated with adenosine (low dose) showing numerous seminiferous tubules with complete maturation and differentiation of spermatogenic cells from spermatogonia up to spermatozoa (sp). (x 100). 3C. High power view (x400) of the section in the testis of rabbit male (pre puberty) treated with adenosine (high dose) demonstrating all stages of spermatogenesis, seminiferous tubules with patent lumen (t) having aggregation of sperms (SP) were seen. 3D. High power view (x400) of the section in the testis of rabbit male (post-puberty) treated with of adenosine (high dose) showing normal testicular structure complete maturation and differentiation of spermatogenic cells, spermatogonia (SG) and spermatocyte (SC). 3E. Section in testis of pre puberty rabbit male (control group) showing somewhat normal structure of seminiferous tubules lined by stratified germinal epithelium (GE). In their lumen few aggregation of sperms (sp) and wide interstitial spaces are seen (Is) with few clusters of interstitial cells (IT). (x100). 3F. Section in testis of (post-puberty) rabbit male (control group) showing seminiferous tubules with maturation up to spermatids, with presence of few numbers of spermatozoa (SP) in their lumen and a wide interstitial spaces (IS).(x 100)
