The clinical performance of the Multiload IUD. II. The influence of age

Abstract

Six thousand four hundred and sixty-two Multiload IUDs were inserted (3606 MLCu375 and 2856 MLCu250). In this study, we determined the acceptance and safety of Multiload IUD use in different age groups. Results were analyzed according to the usual life table method. The pregnancy rate was higher with the users of MLCu250 than with the MLCu375 in a clear relation to age group. Expulsion and bleeding and/or pain rates were higher with younger women in both IUD types.

Dimensions of the endometrial cavity and intrauterine device expulsion or removal for displacement: a nested case–control study

“…The volume of menstrual flow (less than normal or normal), dysmenorrhoea (no or yes), uterine position (anteverted, midposition, or retroverted), and parity (1 or ≥2), which were possible risk factors according to the literature, [8][9][10][11][12][13] were considered as potential confounding factors. In the first multivariate analysis, the above covariates were adjusted to estimate the adjusted odds ratio (aOR).…”

“…9 Young maternal age, heavy menstruation, dysmenorrhoea, uterine position, and the service provider's experience with regard to insertion were reported to be associated with expulsion or removal for displacement. [10][11][12][13][14][15] One hypothesis for IUD expulsion or displacement is dimensional incompatibility between the uterine cavity and the IUD. Castro found that the expulsion rate within 1 and 2 years of MLCu375 was more than four times higher for women with an endometrial cavity length of ≥45 mm, compared with those with a cavity length of <45 mm (P < 0.01) 16 ; however, two prospective studies failed to find any association between endometrial cavity length and the expulsion rate of IUDs.…”
