Uterine perforation and use of the Multiload IUD.

The English language literature on IUDs was reviewed to evaluate the uterine perforation rate associated with use of the Multiload. No reports of cervical perforation were found, and the uterine perforation rate was 0.12/1000 insertions compared to a rate of 0.68/1000 insertions for other copper-bearing IUDs. This lower rate may reflect an under-reporting of uterine perforations in the medical literature, or may represent a truly lower perforation rate due to factors related to the Multiload design and/or its insertion technique.
