Luteinizing hormone secretion by male rat pituitary cells perifused in vitro：effect of experimental left varicocele and orchiectomy
Luteinizing hormone secretion male rat pituitary cells
2009/2/23
It has been shown previously that experimental left varicocele in the rat, results in a bilateral decrease in intratesticular testosterone. In the present work, pituitary responsiveness to GnRH as a...
Cyclophosphamide in the male rat：new pattern of anomalies in the third generation
Cyclophosphamide male rat anomalies third generation
2009/2/23
Several abnormalities, such as postnatal deaths and behavioral impairments, have been previously reported in the progeny of male rats exposed to the cytostatic drug cyclophosphamide 60 days prior to...
Pituitary response to LHRH during chronic renal insufficiency in the male rat
Pituitary LHRH chronic renal insufficiency male rat
2009/2/23
Chronic renal insufficiency was induced in young adult male rats by a 2-step 5/6 nephrectomy. Four weeks after surgery the rats were anesthetized with ketamine and injected with saline or 1, 5, 10...
Testosterone dose-dependency of sexual and nonsexual behaviors in the gonadotropin-releasing hormone antagonist-treated male rat
Testosterone dose-dependency sexual nonsexual behaviors gonadotropin-releasing hormone male rat
2009/2/23
The testosterone dose-dependency of several mating and nonmating behaviors was examined in the male rat, chemically castrated with a GnRH antagonist analog. Graded doses of testosterone enanthate ...

Antimitotic drugs male rat Behavioral abnormalities second generation
2009/2/23
The second generation descended from rats treated either with cyclophosphamide alone or with both cyclophosphamide and vinblastine were investigated. As in the first generation, the offspring were...

cyclophosphamide vinblastine male rat spermatogonia mutation offspring
2009/2/23
The spermatogenesis and the offspring of male rats treated either with cyclophosphamide alone, or with both cyclophosphamide and vinblastine were investigated. The offspring were evaluated for the...
Recovery of gonadal functions in the adult male rat following cessation of five-month daily treatment with an LHRH agonist
LHRH agonist testicular steroidogenesis ventral prostate seminal vesicles spermatogenesis

This study describes the recovery of various parameters of the pituitary-gonadal axis following five months of daily treatment of adult male rats with a potent LHRH (luteinizing hormone-releasing ...
Influence of estradiol on accessory reproductive organs in the castrated male rat. Effects of bromocriptine and flutamide
estradiol accessory reproductive organs castrated male rat
2009/2/19
Estradiol partially maintained the weights of the dorsolateral prostate and seminal vesicles in castrated adult male rats. One group of animals received subcutaneous injections of estradiol (0.01 ...
Prolactin Stimulation of Testicular Steroid Biosynthesis in the Male Rat
prolactin LHRH 17-hydroxylase desensitization steroidogenesis LH receptor prolactin receptor
2009/2/19
The effect of prolactin on testicular steroidogenesis was studied in intact adult male rats and in animals treated for 12 days with the LHRH-agonist [D-Ala6, des-Gly-NH210]LHRH ethylamide (LHRH-agon...
Temporal relation between leptin and various indices of sexual maturation in the male rat
Puberty adipose tissue testosterone gonadotropins
2009/2/18
Recent studies in humans and rhesus monkeys have suggested the possibility that the adipose tissue hormone leptin has a stimulatory and/or permissive effect on the onset of puberty in the male. We...
Inhibin B levels in plasma of the male rat from birth to adulthood：effect of experimental manipulation of Sertoli cell number
Inhibin B levels male rat experimental manipulation Sertoli cell number
2009/2/18
Sertoli cells undergo important changes in their number and function at different ages in the rat and may be the primary source of circulating inhibin B. The aims of this study were 1) to establis...
Estrogen receptor（alpha and beta）expression in the excurrent ducts of the adult male rat reproductive tract
Efferent ductules immunohistochemistry
