The Mirena Coil and The Copper Coil are two similar modes of preventing pregnancy, but they function in different ways. Here, we explain all.
“The Coil” is a very popular contraception choice across the world and within the realms of the coil there are two different types.
The Mirena Coil and The Copper Coil are two similar modes of preventing pregnancy, but they function in different ways.
When we talk about a coil, we are referring to an IUD which stands for Intrauterine Device. This represents the fact that the coil is a device that is placed and fitted within your uterus.
There are several reasons why women choose to opt for the coil as their chosen method of contraception. One of the greatest benefits of this method is the fact that it is so long-lasting. When it has been fitted it is usually effective for several years.
Once fitted, it is 99% effective in preventing pregnancy. It is important to remember that while it will prevent pregnancy it will not protect you from an STI. For this reason, a condom is recommended in addition to being on the coil.
There are two different types of coils. One is hormonal while the other is not.
The Mirena Coil is an example of a coil that is fuelled by hormones. It works via the hormone progestin to prevent a woman from becoming pregnant.
By constantly releasing small amounts of this hormone it does two things. It influences the cervix by encouraging the mucus within it to thicken in consistency. This thicker mucous traps sperm thus preventing it from reaching an egg that has been released from the ovaries.
It can also be responsible for stopping an egg from being released at all. Without an egg being released a pregnancy is not possible as sperm (should they enter) have nothing to fertilise.
The Copper Coil works differently, in the sense that it does not release any hormones. Instead it acts as a physical barrier as the T-shaped device is wrapped in copper which is a toxic substance for sperm.
This prevents the sperm from reaching an egg as they cannot travel past the copper coil and into the uterus via the cervix.
There are pros and cons to all contraception options and in the same way, the different styles of coil will appeal to different people for different reasons. Some women prefer to avoid the Mirena coil as they do not like to tamper with the hormones in their bodies.
Some women find that it can affect their emotional well-being. However, many women like the fact that this type of coil generally leads to them having no monthly period at all. They may experience a couple of months of irregular bleeding before this happens.
The Copper Coil has no hormonal side effects which means breast tenderness and headaches are not an issue. These things can happen with the hormonal coil.
