Combined and national experience of postmenstrual IUD insertions of Nova-T and Copper-T in a randomized study. 1979

T Luukkainen, and N C Nielsen, and K G Nygren, and T Pyörälä, and H Allonen

A randomized comparative study between Nova-T and Copper-T-200 was performed simultaneously in Denmark, Finland and Sweden. The results of 741 postmenstrual insertions with Nova-T and 780 with Copper-T are reported. The pregnancy rate of Nova-T was lower in every age and parity group. The pregnancy rate of Copper-T-200 varied in participating countries, whereas the pregnancy rate of Nova-T was equally low in every country. The termination rate because of expulsion with Nova-T was less affected by age and parity than that of Copper-T. Significant differences in the continuation rates with the same device were found between countries. Removals because of infection showed that women below 25 years of age had a high risk for infection regardless of parity.

D000292	Pelvic Inflammatory Disease	A spectrum of inflammation involving the female upper genital tract and the supporting tissues. It is usually caused by an ascending infection of organisms from the endocervix. Infection may be confined to the uterus (ENDOMETRITIS), the FALLOPIAN TUBES; (SALPINGITIS); the ovaries (OOPHORITIS), the supporting ligaments (PARAMETRITIS), or may involve several of the above uterine appendages. Such inflammation can lead to functional impairment and infertility.
