Ovaries from 10- to 18-day-old chick embryos hypophysectomized by partial decapitation were cultured in vitro and their estradiol secretion was compared to that of ovaries from control embryos. The production of estradiol was not less in the decapitated than in the control embryos at 15-18 days, neither per ovary nor on the basis of ovarian weight. However, the difference was significant at 10-11 days. These results suggest that the hypophysis controls estradiol secretion by the chick embryo ovary in the early stages, but not in the later ones.
通过部分断头法切除垂体的10至18日龄鸡胚的卵巢进行体外培养，并将其雌二醇分泌与对照胚胎卵巢的雌二醇分泌进行比较。在15至18日龄时，断头胚胎卵巢的雌二醇产量无论是按每个卵巢还是按卵巢重量计算，均不低于对照胚胎。然而，在10至11日龄时差异显著。这些结果表明，垂体在早期控制鸡胚卵巢的雌二醇分泌，但在后期则不然。
