Abstract
The effect that lactation might have on intrauterine device (IUD) performance was investigated by using data from a series of multicenter clinical trials. Life-table methods were applied to compare breastfeeding and non-breastfeeding women with respect to IUD expulsion, accidental pregnancy, IUD removal for various reasons, and overall continuation of IUD use. Results indicate that breastfeeding does not increase the risk of expulsion or other events, whether the device is inserted immediately (within ten minutes) or more than 42 days after delivery.
