HCG treatment increases intratesticular pressure in the abdominal testis of unilaterally cryptorchid rats
testis cryptorchidism hCG vascular permeability
2009/2/23
Adult, unilaterally cryptorchid rats were given a single subcutaneous injection of hCG. HCG treatment of 100 I.U. (but not 10 I.U.) resulted in a marked increase in intratesticular pressure (approxi...

/3-endorphin Leydig cells immunohistochemistry
2009/2/23
The immunohistochemical localization of beta-endorphin in the normal testis (two patients) and in the pathologic testis (two cases of Sertoli Cell Only Syndrome, two cases of Klinefelter Syndrome,...
Diverticula of human seminiferous tubules in the normal and pathologic testis
human seminiferous tubules pathologic testis
2009/2/23
The occurrence of diverticula in human seminiferous tubules was investigated in the adult human testis in normal as well as physiologic (aging) and pathologic (germ cell depletion, obstruction of ma...
The selective removal of pachytene spermatocytes using methoxy acetic acid as an approach to the study in vivo of paracrine interactions in the testis
selective removal pachytene spermatocytes methoxy acetic acid paracrine interactions
2009/2/23
Testicular weight and morphology, serum gonadotropins, intratesticular levels of testosterone and ABP levels in testicular interstitial fluid were studied in adult rats at intervals of 1 to 70 days ...
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 ...
The effects of unilateral, experimental varicocele are not mediated through the ipsilateral testis
varicocele rat testis
2009/2/23
Unilateral varicocele has been associated with diminished male fertility in humans and with bilateral physiologic and histologic changes in the testis of humans and laboratory animals. In particul...
Pituitary-testicular function of prostatic cancer patients during treatment with a gonadotropin-releasing hormone agonist analog. II. Endocrinology and histology of the testis
Pituitary-testicular function prostatic cancer patients gonadotropin-releasing hormone
2009/2/23
Endogenous testosterone (T), LH and FSH receptors, and in vitro production of cyclic adenosine-3':5'-monophosphate (cAMP), T and some of its steroid precursors were measured in testicular tissue obt...
Variation in the effect of a nongonadotropic Leydig cell stimulating factor in testicular interstitial fluid after exposure of the testis to a single episode of heat treatment
Variation nongonadotropic Leydig cell testicular interstitial fluid testis
2009/2/23
The activity of a nongonadotropic factor present in rat testicular interstitial fluid and capable of stimulating Leydig cell testosterone production was measured at intervals for 8 weeks after exp...
The incidence of spermatic granulomas and their relation to testis weight after vasectomy and vasovasostomy in Lewis rats
spermatic granulomas testis weight vasectomy vasovasostomy Lewis rats
2009/2/23
The occurrence of spermatic granulomas of the vas deferens was studied in Lewis rats at intervals up to 7 months after vasectomy or vasectomy followed 3 months later by vasovasostomy. The incidence ...
Effects of diazacholesterol dihydrochloride（SC-12937）, an avian antifertility agent, on rat testis
testis germ cell Sertoli cell antifertility agent SC-12937 rat
2009/2/23
The present study was undertaken to evaluate the effectiveness of an avian chemosterilant, 20, 25-diazacholesterol dihydrochloride (SC-12937), on the rat testis. Adult male rats were injected intrap...
