Fifty heifers were twice injected with I.C.I. 80, 996 and inseminated 72 h and 96 h after the second administration. Twenty eight of them (56%) became pregnant. Changes in plasma oestradiol-17 beta, progesterone and LH concentrations around the oestrus following the second injection were similar to those occurring in spontaneous oestrus. The pattern of testosterone secretion resembled that of oestradiol;-17 beta. The highest testosterone concentration (135 +/- 24 pg/ml) was measured on the third day after treatment with I.C.I. 80, 996.
五十头小母牛被两次注射ICI 80996，并在第二次给药后72小时和96小时进行授精。其中二十八头（56%）怀孕。第二次注射后发情期前后血浆雌二醇-17β、孕酮和促黄体生成素浓度的变化与自然发情时相似。睾酮分泌模式与雌二醇-17β相似。在用ICI 80996治疗后的第三天测得最高睾酮浓度（135±24皮克/毫升）。
