有3.5%的不孕症患者由于黄体期功能不全,发生黄体期短,在黄体期时血清中孕酮水平低以及子宫内膜生长延迟等现象。但是在正常子宫内膜及生长延迟的内膜之间孕酮的值常有交错重叠现象。也有研究提示尽管血清中孕酮水平正常,可仍有子宫内膜不完全成熟。由于对黄体功能不全患者子宫内膜孕酮受体的研究较少,本文着重探讨正常子宫内膜及子宫内膜延迟分泌或分泌不全的孕酮受体水平与血清中孕酮水平的关系。 36例因不孕而求诊者被纳入本研究,检查项目包括基础体温,在月经的晚滤泡期、黄体中期及晚期分别采血测孕酮及雌二醇。在预期的月经前2～4天嘱患者复诊并在此时取子宫内膜活检。从子宫 3.5% of infertility patients due to luteal phase dysfunction, the occurrence of short luteal phase in the luteal phase serum progesterone levels are low and the endometrial growth retardation and so on. But in the normal endometrium and growth retardation, the value of progesterone often staggered overlap phenomenon. Research has also suggested that despite the normal serum progesterone levels, there may still be incomplete endometrial maturation. Due to the lack of research on progesterone receptors in endometrium of patients with corpus luteum insufficiency, this article focuses on the relationship between the level of progesterone in serum and the level of progesterone receptor in normal endometrium and endometrium. Thirty-six cases of infertility who were admitted to our study were enrolled in this study. The test items included basal body temperature, menstrual late follicular phase, mid-late luteal phase, and late menstrual blood respectively for progesterone and estradiol. In the expected 2 to 4 days before menstruation Zhu Huanzhe referral and take endometrial biopsy at this time. From the womb
