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
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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...
