OBJECTIVE The aim of this study was to investigate the possible effects of electromagnetic radiation from conventional cellular phone use on the oxidant and antioxidant status in rat blood and testicular tissue and determine the possible protective role of vitamins C and E in preventing the detrimental effects of electromagnetic radiation on the testes. MATERIALS AND METHODS The treatment gro...

As in many mammalian and avian species, testicular androgens or their metabolites activate courtship and copulatory behaviors in adult male zebra finches. However, studies of sexual differentiation of these behaviors and related anatomical structures provide conflicting results. For example, posthatching estradiol can both masculinize courtship and the neural structures involved in song in fema...

objective(s) galectin-3 (gal-3) is a member of the b-galactoside-binding lectins which is expressed in a variety of tissues and plays a role in diverse biological events, such as embryogenesis, adhesion, cellular proliferation, and apoptosis. in this study, the presence and distribution of galectin-3 (gal-3) in the mouse testicular tissue was investigated. materials and methods eight adult nmri...

To verified the target genes of miR-34c, bioinformatics software was used to predict the targets of miR-34c. Three possible target genes of miR-34c related to spermatogenesis and male reproductive development: zinc finger protein 148 (ZNF148), kruppel-like factor 4 (KLF4), and platelet-derived growth factor receptor alpha (PDGFRA) were predicted. Then, the expression of miR-34c and its target g...

BACKGROUND Diabetes mellitus has a variety of structural and functional effects on the male reproductive system. Diabetes results in reduced sperm parameters and libido. The present study aims to investigate the effects of royal jelly (RJ) on reproductive parameters of testosterone and malondialdehyde (MDA) production in diabetic rats. MATERIALS AND METHODS This experimental study was conduct...

Previously, we demonstrated the ability of the normal mammary microenvironment (niche) to direct non-mammary cells including testicular and embryonic stem cells (ESCs) to adopt a mammary epithelial cell (MEC) fate. These studies relied upon the interaction of transplanted normal MECs with non-mammary cells within the mammary fat-pads of recipient mice that had their endogenous epithelium remove...

BACKGROUND Testicular adrenal rest tumors are a benign condition characterized by the presence of remnants of adrenal tissue within the testes that can lead to infertility. Testicular microlithiasis are calculus deposits within the seminiferous tubules. Both are described in congenital adrenal hyperplasia. OBJECTIVES Describe the frequency of testicular adrenal rest tumors and testicular micr...

We have made ten attempts to cultivate vaccine virus in tissue extracts prepared according to the method described by Eagles and Kordi (4). Renal, testicular, and chick embryo extracts were employed with a dermal strain of vaccine virus and with the Levaditi strain of neuro-vaccine virus. In no instance were we able to show that the virus multiplied in the extract media. Both of these strains o...

In this investigation, diabetes was induced in adult male Sprague-Dawley rats by single intraperitoneal injection of streptozotocin (STZ) at 45 mg kg-1 of body weight. A group comprised of 8 diabetic rats was treated with metformin at 100 mg kg-1 of body weight for reducing the elevated blood glucose level. The results revealed that, in the untreated diabetic rats, the body and testicular weigh...

Abstract Objective: Previous studies have indicated the hyperglycemia-induce cell death in various tissues such as brain, kidneys, liver and especially in the testis. Recent studies have reported that diabetes can trigger male infertility. In this study we report the histological analysis of the testis tissue after diabetes type 1 induction in wistar rats. Materials and Methods: At various ti...
