The effect of cortisol on the secretion of sex steroids from cultured ovarian follicles of rainbow trout
In a series of experiments, the effect of cortisol on the ability of rainbow trout ( Salmo gairdneri) ovarian follicles to secrete sex steroids in vitro was investigated. The basal rate of secretion of sex steroids (oestradiol and testosterone) was suppressed in a dose-dependent manner by the additi...
