Fertility after a hormonal IUD
Using a hormonal coil has no effect on subsequent fertility. That is the case regardless of how long a Mirena® is used for. The likelihood of becoming pregnant is exactly the same after removal as if the hormonal coil had not been used. So women who had been using Mirena® got pregnant just as often and just as quickly as women who had been using a copper coil, for example.
However, it should also be taken into account that fertility declines as you get older. So for example, a woman won’t get pregnant as quickly at thirty-five as she would have done at twenty. That’s why it can sometimes take longer for a woman to get pregnant after she stops using an effective method of contraception. It is also important to bear in mind that about 10 per cent of all couples are infertile, regardless of any method of contraceptive they may have been using before.
