Effect of immobilization stress on testosterone and inhibin in male rats
immobilization stress testosterone inhibin male rats
2009/2/23
Adult male Wistar rats were subjected to acute and chronic immobilization stress. Changes in plasma levels of LH, FSH and testosterone and in the content of testicular inhibin and testosterone wer...
Inhibin production by Sertoli cells during testicular regression in the golden hamster
Inhibin production Sertoli cells testicular regression golden hamster
2009/2/23
The objective of this study was to determine if testicular regression in the hamster results in changes in Sertoli cell function that reflect altered pituitary function. Inhibin-like activity was me...
Effect of cryptorchidism and orchidopexy on inhibin secretion by rat Sertoli cells
cryptorchidism orchidopexy inhibin secretion rat Sertoli cells
2009/2/19
The present study explored the effects of experimental bilateral cryptorchidism (of 21-, 28-, and 35-days duration) and orchidopexy (14 and 42 days) in the adult rat on the secretion of inhibin by c...
Effect of cryptorchidism and orchidopexy on inhibin secretion by rat Sertoli cells
cryptorchidism orchidopexy inhibin secretion rat Sertoli cells
2009/2/19
The present study explored the effects of experimental bilateral cryptorchidism (of 21-, 28-, and 35-days duration) and orchidopexy (14 and 42 days) in the adult rat on the secretion of inhibin by c...
Low-molecular-weight Inhibin from Sheep, Human, Rat, and Chicken Testes
inhibin testes avian mammalian
2009/2/19
Low-molecular-weight peptides with inhibin activity have been isolated from sheep, human, rat, and chicken testes by simple gel filtration. These peptides, isolated from avian and mammalian specie...
In Vitro Effect of Inhibin on Cyclic AMP-Phosphodiesterase Activity in Rat Testes
inhibin cyclic AMP-phosphodiesterase
2009/2/19
We have previously reported that incubation of testicular slices with inhibin in the presence of 6 x 10-8 M oFSH resulted in a dose-related reduction in accumulation of cyclic AMP due to a decreas...
Disappearance of Inhibin-like Activity in Bull Seminal Plasma Following Castration
inhibin seminal plasma castration
2009/2/19
Ejaculates from normal and castrated bulls were evaluated for the presence of inhibin-like activity. Inhibin activity found in the seminal plasma of normal bulls became undetectable after castrati...
Concentrations of Immunoreactive Inhibin in Seminal Plasma and Serum from Normospermic, Oligospermic, Vasectomized, Klinefelter's Syndrome, and Sertoli-cell—only Syndrome Subjects
inhibin radioimmunoassay seminal plasma serum
2009/2/18
Semen samples and blood were collected from 57 men: 23 normospermic, 20 oligospermic, 10 vasectomized, two with Klinefelter's syndrome, and two with Sertoli-cell—only syndrome. Inhibin was measure...
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...
Follicle-stimulating hormone and testosterone stimulation of immature and mature Sertoli cells in vitro：inhibin and N-cadherin levels and round spermatid binding
Follicle-stimulating hormone testosterone stimulation immature mature Sertoli cells
2009/2/18
The in vitro response of Sertoli cells isolated from adult rat testes to testosterone (T) and follicle-stimulating hormone (FSH) treatment was investigated. Sertoli cells from >70-day-old Sprague-...
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...
Hormonal regulation of inhibin B secretion by immature rat sertoli cells in vitro：possible use as a bioassay for estrogen detection
Male reproduction estrogens
2009/2/18
The influences of follicle-stimulating hormone (FSH), gonadal steroids, and culture time were studied in relation to inhibin B production by Sertoli cells of immature rats cultured in vitro. Serto...
