Basal body temperature, vaginal hormonocytology, and plasma progesterone concentrations were studied serially in consecutive menstrual cycles of 8 normal subjects and of 10 patients with a history of recurrent early abortions. The menstrual patterns and characteristics of basal body temperature of the patients did not differ significantly from those of control subjects. The mean plasma progesterone concentrations at the midluteal phase of the study cycles of three patients were below those of the lower limit of the control group (4 ng/ml). The results of this study support the conviction that an inadequate luteal phase is more likely to occur in women with a history of recurrent early abortions.
对8名正常受试者和10名有反复早期流产史的患者的连续月经周期进行了基础体温、阴道激素细胞学和血浆孕酮浓度的系列研究。患者的月经模式和基础体温特征与对照组无显著差异。三名患者研究周期黄体中期的平均血浆孕酮浓度低于对照组下限（4 ng/ml）。本研究结果支持这样一种观点，即有反复早期流产史的女性更有可能出现黄体期不足。
