Identification of a potential FSH modulatory protein in human testis and seminal plasma
potential FSH modulatory protein human testis seminal plasma
2009/2/23
A variety of factors capable of inhibiting the in vitro binding of FSH to its receptor have been identified in gonadal tissues from males and females. Interest in these factors has been stimulated b...
Mast cells in the testis, epididymis and accessory glands of the rat：effects of neonatal steroid treatment
Mast cells rat neonatal steroid treatment
2009/2/23
Mast cells in the testis of control adult rats were found almost exclusively around subcapsular blood vessels. Discrete mast cells were distributed throughout the stroma of the epididymis and sex ...
Transplantation of newborn rat testis under the kidney capsule of adult host as a model to study the structure and function of Leydig cells
newborn rat testis kidney capsule adult host Leydig cells
2009/2/23
Newborn rat testis was transplanted under the kidney capsule of adult castrated and uncastrated male rats to develop and characterize a model system for studies on Leydig cell development. Two weeks...
Identification of androgen binding-protein（ABP）from testis and epididymis of the seasonal rodent, Octodon degus（Molina, 1872）
androgen binding-protein (ABP) testis seasonal rodent Octodon degus (Molina, 1872)
2009/2/23
ABP, a Sertoli cell secretory product, was identified in the seasonal rodent Octodon degus (Molina, 1872). It was shown to be present in cytosols from the testis and epididymis. It migrated with a...

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...
Effects of prolactin on luteinizing hormone-stimulated testosterone secretion in isolated perfused rat testis
prolactin testes luteinizing hormone testosterone secretion
2009/2/23
The direct peripheral effect of prolactin on LH-stimulated testosterone secretion was re-evaluated using the intact, isolated, perfused rat testis. In paired experiments, one testis was infused wi...
The correlation between the gossypol contents in blood plasma, rete testis fluid, and cauda epididymal fluid following chronic treatment with gossypol in rats

2009/2/23
Concentrations of gossypol in blood plasma, rete testis fluid, and fluid from the caudia epididymidis were measured simultaneously by high performance liquid chromatography in rats treated with goss...
Radioautographic localization of atrial natriuretic factor receptors in the rat testis
Radioautographic localization atrial natriuretic factor receptors rat testis
2009/2/23
Recent data have suggested that atrial natriuretic factors (ANFs) can modulate Leydig cell functions. An in vitro radioautographic procedure on slide-mounted frozen testicular sections was used to l...
