introduction: since discovery of high frequency waves, their biological effects have been in great attention. increased male fertility problems proposed their possible relation to use of microwaves. testes are of very active body tissues, which can be affected by these waves. age of exposure may also be an important factor. methods: this study was carried out to evaluated testosterone level in ...

objectives: nowadays, a lot of attention has been paid to the therapeutic properties of herbs, including evaluation of the effects of these plants on fertility in laboratory animals. apium graveolens l. (celery) has been widely used in traditional medicine for treatment of various disorders including impotency. therefore, this study was designed to investigate the effects of aqueous extract of ...

the aim of the present study was stereological evaluation of testes of azoospermic animal model using busulfan in rat. three groups of male adult rats were used in this study. the first group was injected by single dose of busulfan (10 mg kg-1) and their testes were removed on day 35 post injection. the second group received double doses of busulfan with 21 days interval and their testes were r...

the aim of the present study was to evaluate the antioxidant effects of aqueous fruit extract of ziziphusjujuba on ethanol-induced oxidative stress and to examine its protective effects on sperm motility and plasma membrane integrity of male wistar rats. adult male rats (n = 28) were divided into four equal groups: the first group served as untreated controls, the second group of rats was given...

Oxidative stress has been identified as one of the factors that affects fertility status. Therefore, this study sought to investigate the inhibitory effect of aqueous extract of Moringa oleifera and Newbuoldia laevis leaves on FeSO4 and Sodium Nitroprusside (SNP) induced lipid peroxidation in rat testes in vitro. Incubation of the testes tissue homogenate in the presence of FeSO4 and SNP caused...

Direct cooling of the testis results in the depletion of most germ cells in vivo. Germ cell-depleted testes are now commonly used to investigate spermatogenic regeneration and can serve as recipients for germ cell transplantation. The present study explored the effects of cooling rat testes on the depletion of endogenous germ cells, spermatogenic regeneration, and Sertoli cell function. Adult r...

objective(s):the aim of this study was to evaluate the oxidative status and dna integrity in testes of wistar rat offspring exposed to omega-9 monounsaturated (mufa) at different times of late organogenesis. materials and methods:sixty female rats were divided into six groups of 10 animals. the first group served as control and received the drug vehicle, olive oil (1 ml/kg/day). the second, thi...

The expression of LDH-C (Lactate dehydrogenase C) gene is restricted in mature germ cells; however multiple splice variants of LDH-C expressed in human cancers and yak normal testes were reported recently. In order to know if there are any LDH-C splice variants in human normal testes, we set out to clone the putative variants in human and rat. Four splicing variants in human testes, 1 splicing ...

The present study was designed to evaluate the effect of ethanol on pituitary adenylate cyclase activating polypeptide (PACAP) and its typ I (PAC1) receptor expression in adult rat testes. Ethanol (3 g/kg i.p., 15% v/v in saline) was administrated to adult male rats for 10 days. Using northern blot analysis, the present study showed the reduction of PACAP mRNA levels in rat testes by ethanol ad...
