Receptivity of female rats has been investigated under chronic experimental conditions. A receptivity index has been worked out for quantitative evaluation. It proved suitable for disclosing stimulatory (2.5 mg noretynodrel, oestradiol propionate) as well as inhibitory (etynodiol diacetate) effects. 2.5 mg noretynodrel has a biphasic effect; causing an inhibition and later an increase in receptivity. Receptivity of untreated female rats is low and can be increased by various steroids; the best treatment was 50 micrograms oestradiol monopropionate administered twice weekly, but this resulted in an inverse mating reaction, with frequent copulations in every phase of the cycle. In untreated females the number of copulations varied widely. Previous deliveries did not influence receptivity and frigidity was also observed.
在慢性实验条件下对雌性大鼠的接受性进行了研究。已制定出一个接受性指数用于定量评估。事实证明，该指数适用于揭示刺激作用（2.5毫克炔诺孕酮、丙酸雌二醇）以及抑制作用（双醋炔诺醇）。2.5毫克炔诺孕酮具有双相作用；先是引起抑制，随后接受性增加。未接受处理的雌性大鼠接受性较低，各种类固醇可提高其接受性；最佳处理方法是每周两次给予50微克单丙酸雌二醇，但这会导致交配反应相反，在周期的每个阶段都会频繁交配。在未接受处理的雌性大鼠中，交配次数差异很大。先前的分娩并未影响接受性，且还观察到了性冷淡。
