Effects of a levonorgestrel intrauterine system versus a copper intrauterine device on menstrual changes and uterine artery Doppler.

What Was Tested

The paper reports a study of Copper (Supplement), published as a randomized controlled trial.

To compare the effects of a levonorgestrel-releasing intrauterine system (LNG-IUS) and a copper intrauterine device (Cu-IUD) on menstrual changes and uterine artery Doppler indices.

Who Took Part

According to the abstract, 306 women were involved.

PubMed indexes the participants as young adults and adults, women only.

A randomized clinical trial was conducted at Menoufia University Hospital, Egypt, between December 2016 and August 2017. 306 multiparous women desiring intrauterine contraception were randomly assigned to LNG-IUS (n=152) or Cu-IUD (n=154).

How the Study Was Run

In design terms this was a randomized study.

Because people in this Copper (Supplement) study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Uterine artery pulsatility index (PI) and resistant index (RI) were measured before use, and 3 and 6 months after insertion, and associations with abnormal bleeding were evaluated.

What Was Measured

Topics PubMed links to this paper include Contraceptive Agents, Female, Egypt, Intrauterine Devices, Copper, Intrauterine Devices, Medicated, Levonorgestrel, Menorrhagia and Ultrasonography, Doppler.

The authors tagged it with the keywords Levonorgestrel-releasing intrauterine system and Long-acting reversible contraception.

What This Means in Plain Language

The paper is a randomized study of Copper (Supplement) in 306 women.

With several hundred people or more, it is a fairly large study for this kind of research.
