Abstract:
The deposits on the surface of stainless steel IUDs may appear after IUD placed in the uterine cavity for a period of time and Calcium is the most important one among the elements of deposits.This paper illustrates the confi dence level from mathematical models which shows the relations among the three groups (pregnancy (P),bleeding (H) and control (C)) and the time of duration of IUD in situ.Their confidence levels all reach to 90%.It verifies the relation between the amount of Calcium and P,H,C,Curves.In addi- tion,the suitable amount of Calcium may be increase the contraceptive effect that is turned out by the mathematical proof.It is valuable for the improvement of IUDs with theoretical and pracrical signficances.
