Background and Objective: It is conceivable that caffeine consumption would induce gonadal changes. The aim of this study is to assess the impact of embryonic caffeine exposure on rat testis and prostate. Materials and Methods: Female rats were divided into (n=7): A control, only received drinking water. B and C groups received caffeine low dose (26 mg/kg) and high dose (45 mg/kg) respectively...

Background: Acyclovir (9-(2-hydroxyethoxymethyl) guanine) (ACV) is an acyclic nucleoside analogue that has shown a potent antiviral activity, and it is known to inhibit the replication of herpesviruses including herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), varicella- zoster virus (VZV), and Epstein-Barr virus (EBV) in cell cultures and in animals. ACV is khown to be toxic to gonads,t...

After a single feeding or intravenous injection of 7,12-dimethylbenz[a]anthracene, the testis of rat was severely and selectively damaged, whereas the ovary of sisters was spared from injury. After many weeks, complete recovery of the testis ensued. The destructive effect of 7,12-DMBA on testis was not shared by other powerful carcinogenic hydrocarbons; 3-methylcholanthrene; benzo[a]pyrene; 2-a...

Objective: Age brings about changes to the oxidant and antioxidant balance of male testis that give rise loss fertility. The Ferula elaeochytris root extract (FE), contents anti-inflammatory component, have been used treat infertility by local people for centuries. main objectives this study were determine whether FE was effective on sperm quality, spermatogenesis, apoptosis oxidative stress in...

BACKGROUND Certain phthalates can impair Leydig cell distribution and steroidogenesis in the fetal rat in utero, but it is unknown whether similar effects might occur in the human. OBJECTIVES Our aim in this study was to investigate the effects of di(n-butyl) phthalate (DBP), or its metabolite monobutyl phthalate (MBP), on testosterone production and Leydig cell aggregation (LCA) in fetal tes...

Background: Busulfan is a chemotherapy drug that is widely used for cancer treatment. However, administration of busulfan to male patients with malignant diseases may cause temporary or permanent sterility. Therefore, research into drugs or Materials to reduce the side effects of busulfan on the male reproductive system is necessary. In the present study the protective effects of L-carnitine an...

Lysozyme-like proteins (LYZLs) belong to the class of c-type lysozymes and are not well characterized in many species including the rat. In this study, using in silico and molecular biology techniques, we report the identification, cloning and characterization of rat Lyzl4 gene and also determine the expression pattern of Lyzl1, Lyzl3 and Lyzl6. The rat Lyzl genes were found to be distributed o...

Chlorpyrifos (CPF) is a broad spectrum organophosphate pesticide used for agricultural health purposes. Its principal mechanism of toxicity is the inhibition of acetylcholinesterase. The purpose of present study was to investigate the effects of CPF on testicular tissue and sperm parameters in male rats. Thirty-two healthy male rats were divided into two groups: a CPF-exposed group and a contro...

The rat has been explored in detail for its in utero susceptibility to male reproductive tract malformation following phthalate exposure. Few other species have been studied in detail, and it is important for both mechanistic and risk assessment purposes to understand the species specificity of this response. We investigated the response of the fetal mouse testis to phthalate exposure and compa...
