Long-term release of copper from two Multiload IUD models: MLCu250 and MLCu375

  • Published:
Advances in Contraception

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.
