All coils are not the same
Hormonal coils and copper coils look very similar, but they work in very different ways:
|The Mirena® hormonal coil||Copper coils|
|How do they work?||The hormone levonorgestrel is released directly into the womb; cervical mucus becomes thicker; womb lining becomes thinner; mobility and viability of sperm is impaired.||Copper ions impair mobility of sperm|
|How safe are they?||For every 1000 women using it for a year, two will become pregnant.||For every 1000 women using it for a year, 6-8 women will become pregnant.|
|How tolerable are they?||Periods become lighter and less painful; may be some spotting at first; protection from infection.||Longer and heavier periods; no protection from infections|
|How much do they cost?||Depending on the coverage by the health insurance.
– The Mirena costs around € 150 plus the doctors fee for the placement;
– Cost-savings on feminine hygiene products
|Depending on the coverage by the health insurance.
– The IUD costs €10-20 plus the doctors fee for the placement

|How long do they last?||5 years||5 years|
