Abstract

Early chorionic activity was assessed in the premenstrual days by means of serum HCG beta-fraction. As control, a group of women with no contraceptive use was studied; early chorionic activity was detected in 31.8% of the cycles. In the group bearing an inert IUD the incidence was 20%, which did not differ from the control; while in the medicated IUD groups (Cu-IUD and LNG-IUD) the incidences were 4.8% and nil, respectively. Both medicated IUD groups showed a significant difference when compared with the control, as well as the inert IUD groups. The meaning of these findings, pointing out differences in the main mechanism of action between inert and medicated IUDs, is discussed.

摘要

在月经前期通过血清人绒毛膜促性腺激素β亚基评估早期绒毛膜活性。作为对照，研究了一组未使用避孕措施的女性；在31.8%的月经周期中检测到早期绒毛膜活性。在使用惰性宫内节育器的组中，发生率为20%，与对照组无差异；而在含药宫内节育器组（铜宫内节育器和左炔诺孕酮宫内节育器）中，发生率分别为4.8%和零。与对照组以及惰性宫内节育器组相比，两个含药宫内节育器组均显示出显著差异。讨论了这些发现的意义，指出了惰性和含药宫内节育器主要作用机制的差异。
