本实验使用家兔诱导排卵动物模型,分别观察了消旋18-甲基炔诺酮和左旋18-甲基炔诺酮对于用铜盐、由PMSG和HCG以及由LH-RH诱导的家兔排卵的影响。实验共分三大组:一组于实验第1-3天皮下注射雌二醇(100μg/天/只),第四天经耳縁静脉注射1％醋酸铜(0.4cc/kg)。24小时后处死并检查排卵点。二组于实验第1-2天皮下注射雌二醇,第4天皮下注射一次LH-RH In this experiment, rabbit ovulation induction animal models were used to observe the effects of racemic 18-norgestrel and levonorgestrel on ovulation induced by copper salts, PMSG and HCG, and by LH-RH Impact. The experiment was divided into three groups: one group received subcutaneous injection of estradiol (100μg / day / day) on the first 1-3 days of the experiment, and 1% copper acetate (0.4cc / kg) on ​​the fourth day via the ear. After 24 hours, sacrifice and check for ovulation. The two groups were injected with estradiol subcutaneously on the first 1-2 days of the experiment and LH-RH subcutaneously on the fourth day
