采用体外孵育技术，研究了不同类固醇类化合物对黄花鱼和花鱼卵母细胞生发泡破裂(GVBD)和排卵的影响。孕激素和11-脱氧皮质类固醇均可诱导河豚GVBD。孕激素和11-脱氧皮质类固醇也能诱导黄鱼卵母细胞发生GVBD；然而，在较高浓度下，无论有无生殖细胞成熟，它们都能诱导相当比例的排卵。在较低浓度下，只有20β-二氢孕酮继续诱导排卵，而只有11-脱氧皮质醇能非常有效地诱导GVBD。在黄花鱼和鲑鱼中，11-氧合皮质类固醇或雄激素在诱导GVBD或排卵方面都相对无效。
The effects of various steroids on germinal vesicle breakdown (GVBD) and ovulation were investigated in yellow perch (P. flavescens) and brook trout (S. fontinalis) oocytes using an in vitro incubation technique. Both progestogens and 11-deoxycorticosteroids induced GVBD in brook trout. Progestogens and 11-deoxycorticosteroids also induced GVBD in yellow perch oocytes; however, at higher concentrations they induced a significant percentage of ovulation with or without germinal maturation. At lower concentrations only 20.beta.-dihydroprogesterone continued to induce ovulation while only 11-deoxycortisol was very effective in inducing GVBD. In both yellow perch and brook trout, 11-oxygenated corticosteroids or androgens were relatively ineffective in inducing either GVBD or ovulation.
