Abstract

Decrease of mean copper content was assessed for two commercial types of Multiload IUD with different copper loads. Mean daily loss of copper amounted to about 18 mcg and 30 mcg for MLCu250 and MLCu375 devices, respectively. On the basis of these estimates, we conclude that both these IUD models can be considered long-lasting interceptive agents.

Resumé

On a évalué, sur deux types de DIU Multiload disponibles sur le marché contenant des pourcentages différents de cuivre, la baisse de la teneur moyenne en cuivre. La perte journalière moyenne de Cu des modèles MLCu250 et MLCu375 s'élevait respectivement à environ 18 mcg et 30 mcg. Sur la base de ces estimations, nous avons conclu que ces deux modèles de DIU pouvaient être considérés comme des agents contraceptifs de longue durée.

Resumen

Se evaluó la disminución del contenido medio de cobre en dos tipos comerciales de DIU Multiload con cargas diferentes de cobre. La pérdida media de cobre fué de aproximadamente 18 mcg y de 30 mcg para los dispositivos MLCu 250 y MLCu 375 respectivemente. En base a estas estimaciones se concluyó que ambos modelos de DIU pueden ser considerados como agentes interceptores de larga duración.
