Intrauterine contraception in nulligravid vs parous women.
The performance of MLCu-250 IUDs inserted in 525 nulligravid women was studied for four years and is compared to the results obtained in the same period from 2770 parous women using TCu-200, 7Cu-200 and Nova-T IUDs. In every case the choice of the particular IUD model took into account hysterometry and diameter of the inner cervical orifice in order to aim at the highest theoretical efficacy. The MLCu-250 in nulligravid women produced failure and expulsion rates below those of the other models in parous users; no difference was observed in the case of removal because of bleeding or pain. Finally, there was no case of subsequent infertility or pelvic inflammatory disease (PID) recorded among nulliparae. These results suggest that an adequate choice of the IUD model for nulliparous women with low risk of PID gives as reliable results as in multiparous women.
