目的:探讨月经周期血清孕酮水平变化与妊娠的关系。方法:从月经第3天开始,用尿促性腺激素(HCG)并开始采血至排卵日为止,测定不孕症患者血清中孕酮水平,排卵后14d查血HCG,根据血HCG结果分为妊娠组与非妊娠组。结果:妊娠组早卵泡期(月经第3、5天)孕酮明显低于非妊娠组(P<0.05),而卵泡成熟期及黄体期比较差异无统计学意义(P>0.05)。结论:早卵泡期孕酮水平与妊娠率有密切关系。
Objective: To investigate the relationship between serum progesterone level and pregnancy during the menstrual cycle. Methods: From the third day of menstruation, serum progesterone level was measured with urine gonadotropin (HCG) and blood sampling until the day of ovulation. Serum HCG levels were determined 14 days after ovulation, and were divided into pregnancy Group and non-pregnancy group. Results: The progesterone in the early stage of pregnancy (3rd and 5th day of menstruation) was significantly lower than that of the non-pregnant group (P <0.05). There was no significant difference in the mature stage and the luteal phase among the pregnant women (P> 0.05). Conclusion: Progesterone level in early follicular phase is closely related to pregnancy rate.
