Age-related changes in the concentration of cytosolic androgen receptors in the epididymis, vas deferens and seminal vesicle of maturing male mice
Age-related changes cytosolic androgen receptors epididymis
2009/2/23
In this study, changes in the number of androgen binding sites that occur in cytosols of epididymis, vas deferens and seminal vesicle of mice from 10 to 90 days of age are described. Specific satura...
Autoradiographic localization of tritium-labeled dihydrotestosterone in human vas deferens
Autoradiographic localization tritium-labeled dihydrotestosterone human
2009/2/23
The human vas deferens was examined autoradiographically for the presence and distribution of androgen receptors. Samples of vas deferens from the region proximal to the testis and the region at the...
A Case of Bilateral Absence of the Vas Deferens and the Body and Tail of the Epididymis in Association with Multiple Congenital Anomalies

A patient presenting with infertility was found to have bilateral agenesis of the vas deferens and body and tail of the epididymis in association with cleft mitral valve, epiphyseal dysplasia, polyd...
Cell- and region-specific localization of lysosomal and secretory proteins and endocytic receptors in epithelial cells of the cauda epididymidis and vas deferens of the adult rat
Cell- and region-specific localization secretory proteins endocytic receptors
2009/2/18
The epithelial cells lining the cauda epididymidis and vas deferens are active in endocytosis and have an abundance of lysosomes and a well-characterized secretory apparatus. However, little is kn...
Obstruction of the vas deferens alters protein secretion by the rat caput epididymidal epithelium in vivo
protein secretion rat caput epididymidal epithelium
2009/2/18
Obstruction of epididymal lumen fluid flow alters the intraluminal environment and potentially changes epididymal epithelial cell function when those functions are dependent on intraluminal regulato...

Principal cells vas deferens water transport steroid synthesis adult rat
2009/2/18
Principal cells show marked structural differences in the proximal, middle, and distal regions of the vas deferens, reflective of diverse functional activities. In the present study, we performed el...
Immunocytochemical localization of the Ya, Yb1, Yc, Yf, and Yo subunits of glutathione S-transferases in the cauda epididymidis and vas deferens of adult rats
Immunocytochemical localization Ya Yb1 Yc Yf glutathione S-transferases cauda epididymidis
2009/2/18
Glutathione S-transferases (GSTs) are dimeric proteins grouped into five classes based on the degree of amino acid homology of their subunits. They are involved in cellular detoxification through ...
Morphometric and immunocytochemical study of the fetal, infant, and adult human vas deferens
Epithelium testicular developmental phases
2009/2/17
The human vas deferens (VD) is often considered simply as a conduit to transfer mature sperm from the epididymis to the ejaculatory duct. The cells that make up the epithelium of the VD, however, ex...
Sperm autoantigens recognized by autoantibodies in developing rats following prepubertal obstruction of the vas deferens
Spermatozoa autoantigens development puberty
2009/2/16
Sperm protein autoantigens recognized by serum antisperm autoantibodies during development following vas deferens obstruction were studied using western blot analysis. At age 10 days, rats in an obs...
Temporal appearance of antisperm antibodies during sexual maturation of rats after obstruction of the vas deferens
Autoantibodies spermatozoa vas deferens sparmatic
