Copper IUDs, a type of non-hormonal contraceptive. To understand how it works we will need a simple introduction to how menstruation works.


Every month, there’s the discharge of the ovum from the ovaries of women in their reproductive age. The ovum migrates to the uterus under the influence of various hormones. If the ovum doesn’t get fertilized by sperms or the male counterpart, there occurs a discharge of the ovum along with the lining of the uterus. Such condition occurs every month, known as periods or menstruation.

On contrary, if the ovum gets fertilized by the sperm, there occurs the formation of the zygote, the cell that’s gonna subsequently develop into a child.

Now, how do copper IUDs fit here? Copper IUDs, after getting placed on the uterus engage the immune or protective mechanism in your body. It basically kills off the sperm before it gets a chance to fertilize the ovum, preventing pregnancy.

As such, there’s no hormonal factor working in this case. So is Copper IUD late period, just a myth?
