Brief summary

To investigate whether vaginal dinoprostone administered before the levonorgestrel-releasing intrauterine system(IUs) insertion reduces failed insertions, insertion-related complications, and pain in Women With no Previous Vaginal Delivery.

Detailed description

Long-acting reversible contraception methods are highly effective methods for reduction of the unplanned pregnancy rate worldwide. The intrauterine device is a single procedure that provides reliable, effective and long term contraception for many women. However, the insertion procedure can be associated with a troublesome degree of pain that prevent some women from choosing its use. Different interventions have been described to decrease pain perception during intrauterine device insertion with no agreement on an effective one.
