American scientists have done research on bleeding, cramps and satisfaction of new users of a copper IUD. This showed that 6 months after placement women are more satisfied with their copper IUD.

77 women, who were given a copper IUD, were asked to keep track of the amount of blood loss and cramps. They were also asked about their satisfaction with their new method of contraception. This study showed that during 6 months the bleeding decreased by 23%, the cramps decreased and thus the satisfaction with their copper IUD increased.

This new study offers healthcare professionals the opportunity to give women objective information about what to expect during counselling on contraception methods. Women who make a conscious choice for contraception on the basis of reliable information tend to be more satisfied and less likely to stop using it early.
