Evidence that in a physiological setting Sertoli cell number is the major determinant of circulating concentrations of inhibin B in the adult male rhesus monkey（Macaca mulatta）
Sertoli cell number circulating concentrations inhibin B adult male rhesus monkey
2009/2/18
The relationship between changes in Sertoli cell number and function and changes in circulating inhibin B concentrations was investigated following unilateral orchidectomy (UO) in the adult rhesus...
Evidence for catecholaminergic, neuronlike cells in the adult human testis：changes associated with testicular pathologies
catecholaminergic neuronlike cells adult human testis
2009/2/18
Neuronlike, catecholaminergic cells expressing tyrosine-hydroxylase (TH) have recently been found in the testis of a nonhuman primate species, the rhesus monkey. We examined whether neuronlike cel...
Principal cells of the vas deferens are involved in water transport and steroid synthesis in the adult rat
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 ...
Testosterone-dependent restoration of spermatogenesis in adult rats is impaired by a 5alpha-reductase inhibitor
Testosterone-dependent restoration spermatogenesis adult rats 5alpha-reductase inhibitor
2009/2/18
Germ cell development (spermiogenesis in particular) in the adult rat is known to be testosterone dependent. Recently we proposed a role for the 5alpha reduction of testosterone to dihydrotestostero...
Follicle-stimulating hormone is required for the initial phase of spermatogenic restoration in adult rats following gonadotropin suppression
Testosterone germ cell spermatogonia stereology
2009/2/18
The role of follicle-stimulating hormone (FSH) in adult rat spermatogenesis is unclear. Although exogenous testosterone (T) restores spermatogenesis following gonadotropin-releasing hormone (GnRH)...
Androgen binding protein secretion and endocytosis by principal cells in the adult rat epididymis and during postnatal development
Androgen binding protein secretion endocytosis principal cells adult rat epididymis
2009/2/18
Androgen binding protein (ABP) has been shown to be secreted by Sertoli cells and to be actively taken up by the efferent ducts and proximal caput epididymidis and, yet, to be present at high concen...
Apoptosis pattern elicited by several apoptogenic agents on the seminiferous epithelium of the adult rat testis
Apoptosis pattern apoptogenic agents seminiferous epithelium adult rat testis
2009/2/17
Spontaneous germ cell death during spermatogenesis is an important event, and the usefulness of the seminiferous epithelium as an in vivo model to study apoptosis has been evidenced. Nevertheless, the...
Quantitative（stereological）study of the normal spermatogenesis in the adult monkey（Macaca fascicularis）
normal spermatogenesis adult monkey
2009/2/17
Germ cell and Sertoli cell numbers were estimated in six normal adult monkeys (Macaca fascicularis) using a contemporary unbiased and efficient stereological method--the optical disector. The da...
Effect of chorionic gonadotropin and flutamide on Leydig cell and macrophage populations in the testosterone-estradiol-implanted adult rat
chorionic gonadotropin Leydig cell macrophage populations testosterone-estradiol-implanted adult rat
2009/2/17
The objective of this study was to investigate the role of androgens and nonandrogenic Leydig cell products in maintaining Leydig cell and macrophage numbers in the testis of the adult rat. Adult ...
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...
Estrogen receptor（alpha and beta）expression in the excurrent ducts of the adult male rat reproductive tract
Efferent ductules immunohistochemistry
2009/2/17
The understanding of estrogen's function in the male reproductive tract is limited, and estrogen receptor (ER) localization in the reproductive tract of the adult male rat has not been described. ...
The effects of gonadotropin-releasing hormone immunization and recombinant follicle-stimulating hormone on the Leydig cell and macrophage populations of the adult rat testis
Stereology morphometry optical disector leucocytes
2009/2/17
The objective of this study was to investigate the role of the gonadotropins and, in particular follicle-stimulating hormone (FSH) in maintaining the Leydig cell and macrophage populations of the adul...
Differential methylation in steroid 5 alpha-reductase isozyme genes in epididymis, testis, and liver of the adult rat
