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...

Background: Opium, as the most widely known opioid in the world, has significant effects on reproductive organs, which can affect fertility and influence the next generation. This study was performed to investigate the effects of opium administration on histological changes and spermatogenesis indexes in the testis of adult male rats. Methods:A total of 50 adu...

Introduction: Cyclophosphamide (CP) is used for the treatment of various cancers. In spite of its therapeutic importance, a wide range of adverse effects such as reproductive toxicity has been observed following the administration of this drug in human and experimental animals. In the current study, we have investigated the adverse effects of CP on morphology and histology of testis rats. M...

Background: The aim of this study was to investigate the short term protective effect of oxytocin on testicular ischemia reperfusion injury immediately after detorsion in a rat model. Materials and Methods: Twenty adult rats were randomly divided into four groups: Control, Ischemia- Reperfusion (IR), Oxytocin and IR+ Oxytocin. Testicular ischemia was achieved by torsion of the left testis 720° ...

AIM To evaluate the protective/ameliorative effects of vitamin E (vit E) on ethane dimethane sulfonate (EDS)-induced testicular toxicity in rats. METHODS The rats were assigned to eight groups, seven rats in each, and were injected intraperitoneally with vehicle, a single dose of ethane dimethane sulfonate (EDS) (75 mg/kg bodyweight), vit E (100 mg/kg bodyweight) or EDS + vit E for 3? days. T...

BACKGROUND Severe spermatogenic compromise may be the result of a Y-chromosomal deletion of the AZFc region. Prior studies are limited to relatively small numbers of AZFc-deleted men. In this study, we have fully characterized 42 infertile men with a Y chromosome microdeletion strictly confined to the AZFc region, and we report on 18 children conceived through the use of ICSI. METHODS A total...

Background: There is a rapidly growing trend in the consumption of herbal remedies in the developing countries. The Phoenix dactylifera date palm pollen (DPP) is used in the traditional medicine for male infertility. The aim of this study was to determine the effects of orally administered DPP on the reproductive system of adult male rats. Methods: Fifty Sprague-Dawley rats were maintained acco...

A 72-year-old Caucasian male who presented with haematuria in July of 2000 was found to have a large left-sided bladder tumour. He underwent a transurethral resection of the tumour and surveillance program. In October 2008 he underwent a transurethral resection of the prostate (TURP). Histology of the prostatic chippings showed poorly differentiated TCC with prostatic invasion. A CT of his ches...
