Background: The objective of this study was to investigate the effect of high and moderate summer ambient temperatures on testicular structures and endocrine profile of developing ram lambs. Materials and Methods: Twenty fall-born ramlambswere randomly divided into two groups: animalswere kept outdoor (n=10) under ambient temperature (31-50°C) or maintained indoor (26-32°C) from May to October ...

The rodent testis is well established as a site of immune privilege where both innate and acquired immune responses are suppressed. Immune cells and responses within human or non-human primate testes, by contrast, are poorly characterised. This study used multi-colour flow cytometry to characterise the leukocytes in testicular cells isolated from 12 young adult pigtail macaques (Macaca nemestri...

herein we report a case of primary leiomyosarcoma of testis, which was believed to originate from normal testicular structures.  it contained smooth muscle cells, blood vessels and contractile cells of the seminiferous tubules.  no evidence of tumor spread was found. treatment consisted of orchiectomy with high ligation of the spermatic cord.  the patient received no adjuvant therapy and there ...

The epididymis of the lizard Eutropis carinata can be divided into four regions viz., an initial segment (extra testicular) Efferent ductules (Eds) and three regions, anterior region, a broad middle, narrow posterior, comparable to caput, corpus, cauda epididymidis mammals. region is closely associated with whitish testicular), (Eds). epididymal wall consists epithelial layer lining lumen resti...

Background: The complications of diabetes are the major problems that occur in diabetic patients. It has been reported that, insulin insufficiency and the impairment of regulatory action of this hormone on Leydig and Sertoli cells have an important role in testicular alterations. Testicular disorders and change in normal spermatogenesis is one of the consequences of diabetes. This study was des...

Background: Proliferation of spermatogonial stem cells (SSCs) can be a treatment for infertile men. Here, we design an efficient method based on culturing in the presence of Sertoli cells to improve the expression level of some specific spermatogonia stem cell genes during two weeks post culture. Materials and Methods: Cells were derived from neonatal (2-6 days old) mice testes and were cultur...

Fructolysis is stimulated 3to 5-fold in bovine epididymal spermatozoa when the latter are preincubated with caffeine, theophylline, cyclic adenosine 3’, 5’-monophosphate (CAMP), and N6, 02’-dibutyryl adenosine 3’,5’-monophosphate’((Bt)2CAMP). No increase in fructolysis is observed if phosphodiesterase inhibitors or cyclic nucleotides are added to freshly washed cells or to preincubated cells ju...
