Leydig cell and extracellular matrix effects on Sertoli cell function：biochemical and morphologic studies
Leydig cell extracellular matrix Sertoli cell function
2009/2/23
The reciprocal influence between Leydig and Sertoli cells prepared from pig testis were studied by coculture of both types of cells in either plastic dishes or dishes coated with basement membrane...
Steroid metabolism and morphologic features of the human testis
Steroid metabolism morphologic features human testis
2009/2/23
Serum FSH, LH, and testosterone were studied in 114 infertile men with poor sperm production. Testicular biopsies were taken and classified morphologically. In 90 specimens, the pattern of convers...
Morphologic changes induced by short-term ischemia in the rat testis are not affected by treatment with superoxide dismutase and catalase
short-term ischemia rat testis superoxide dismutase and catalase
2009/2/23
Short-term testicular ischemia was induced unilaterally by ligating the testicular artery for 60 or 100 minutes in adult rats. After 7 days, the rats were fixed by vascular perfusion. The effect of ...
Morphologic and endocrine changes in the reproductive organs in rats implanted with gossypol acetate pellet in the testis
Morphologic and endocrine changes reproductive organs rats implanted gossypol acetate pellet
2009/2/23
Gossypol acetate pellets in concentrations ranging from 0.5, 1.0, 5.0, 10.0, to 20.0 mg were implanted in the testis of rats for a period up to 7 weeks. The implant was made in one testis only. In...
In vitro differentiation of rat seminiferous tubular segments from defined stages of the epithelial cycle morphologic and immunolocalization analysis
rat seminiferous tubular segments defined stages epithelial cycle morphologic immunolocalization analysis
2009/2/23
Rat seminiferous tubule segments have been cultured in chemically defined medium (F12/DMEM 1:1) without added hormones or growth factors. The segments (1-2 mm) were isolated from defined stages of t...
Animal model of isolated gonadotropin deficiency. II. Morphologic responses to LHRH immunoneutralization
hypogonadotropic-hypogonadism LHRH dog immunohypophysectomy testis prostate excurrent
2009/2/19
Morphologic changes in the male reproductive system of mongrel dogs immunized against LHRH were quantitated using linear measurements and morphometric techniques at the light-microscopic level. Two ...
Morphologic changes in efferent ductules and epididymis in estrogen receptor-alpha knockout mice
Morphologic changes efferent ductules epididymis estrogen receptor-alpha
2008/12/25
Estrogen has been shown to have an important role in fluid reabsorption in efferent ductules of the testis. Our previous study of the estrogen receptor-alpha knockout mouse (ERKO) showed that the ...
