Background: Lead (Pb) is one of the most important environmental pollutants that affect the male reproductive system. The aim of this study was to investigate the protective effect of green tea extract on lead-induced oxidative stress, apoptosis and morphometric changes in male mouse epididymis. Materials and Methods: Forty adult male mice were randomly divided into four groups (n= 10), as foll...

background: sulphites are widely used as a preservative and antioxidant additives in the food and pharmaceutical industries. many types of biological and toxicological effects of sulphites in multiple organs of mammals have been shown in previous studies. objective: the aim of this study was to investigate the effects of sodium metabisulfite (smb) on testicular function and morphometric values ...

in the present study, the fertilizing potential of semen recovered from slaughtered bulls epididymis was evaluated after cryopreservation, by conventional techniques and flow cytometry methods. the cauda epididymal was dissected and sperm were recovered and evaluated for volume, sperm concentration, and membrane and acrosome integrity using a flow cytometer. sperm fertility potential was tested...

The biotin-avidin immunoperoxidase staining method and antisera against highly purified porcine relaxin were utilized to localize relaxin in the male genital tract. Formalin-fixed tissue specimens from the prostate gland, the testis, epididymis, vas deferens and the seminal vesicle were studied. Specific relaxin immunoactivity was seen in the glandular epithelium of the prostate and also in the...

The normal male external genitalia include the testicles with the epididymis attached posteriorly and the vas deferens arising from this. This case describes an anatomical variation of this normal anatomy not previously reported in the literature. A 17-year-old boy presented with symptoms of intermittent testicular torsion and underwent scrotal exploration. On the left side there was a bell-cla...

The proteins of epididymal tissues and fluids recovered from five regions of the human epididymis were separated by polyacrylamide gel electrophoresis under denaturing conditions. Among the 60 peptides identified, eight appeared to be expressed solely in the epididymal duct when compared to serum and testis proteins. Three of these (92, 47 and 24 Kd) showed a degree of regional specificity in f...

The epididymis exhibits region-specific as well as cell-specific patterns of gene expression within the epithelium. The spatial and temporal patterns of gene expression originate during development and are critical to the formation and maintenance of a fully functional epididymis. Despite the number of mechanisms reported to contribute to the regulation of eukaryotic gene expression, little is ...

this study was carried out to investigate the histological and anatomical description of the male genital tract in iranian native white roosters (iwr). the seminiferous tubules had a dense and compact organization. an average of 12 layers of cells was seen in the seminiferous tubules epithelium. the spermatogonal cell layer showed some variation between different birds in 1-3 layers; however, t...

We have investigated the toxic effects of trichloroethylene (TCE) on the epididymis and epididymal sperm in mice. Mice were exposed to TCE (1000 ppm) by inhalation for 6 h/day for 5 days/week for 1 to 4 weeks. Segments of the epididymis (caput, corpus and cauda) were examined by light and electron microscopy. At the light microscopic level, degeneration and sloughing of epithelial cells were ev...

Jeong Kyun Yeo From the Department of Urology, College of Medicine, Inje University, Pusan, Korea We report a rare case of a metastatic tumor of the tunica vaginalis and epididymis with hydrocele from occult gastric cancer. A 72-year-old patient showed a painless scrotal swelling. Scrotal ultrasound showed a right hydrocele and a follow-up hydrocelectomy showed a mass on the epididymis. The ope...
