Spiral with hormones
Contraceptive coils are differentiated between copper coils and hormone coils, which achieve their contraceptive effect in different ways. Hormone coils contain the hormone levonorgestrel. This has different effects on the body.
First of all, similar to the minipill, the cervical mucus becomes firmer and more impermeable to sperm so that they cannot reach the uterus. The hormone also reduces the formation of new lining of the uterus. In the female cycle, part of the lining of the uterus is rebuilt every month and expelled again during menstruation.
The hormone spiral thus ensures poorer implantation of the egg and weaker, often less painful menstrual bleeding. Levonorgestrel also reduces the mobility of the fallopian tubes so that the egg cells can be transported more difficultly. However, ovulation is not prevented by the hormone coil, so that women continue to have a regular cycle, although this can be significantly reduced.
Some women stop bleeding under the IUS. Depending on the manufacturer, the IUS can be worn for three to five years before they need to be changed. The Pearl Index, i.e. the probability of unwanted pregnancies, is slightly better with the IUS than with the copper IUD.
Does the spiral influence the period?
The coil, unlike the pill, does not prevent ovulation.However, the hormone coil can restrict the build-up of the endometrium to such an extent that women have significantly weakened or missing periods. The copper spiral often increases menstrual bleeding. This difference should be considered when choosing the IUS, as women with menstrual pain and heavy bleeding are more likely to benefit from the IUS. In the case of very irregular bleeding, the gynaecologist should be contacted, as this may also indicate that the IUD is in the wrong position.
Spiral and tampon – is that possible?
The spiral lies in the uterus and only the return threads reach a short distance into the vagina. Tampons on the other hand are inside the vagina and therefore outside the uterus. The use of tampons is therefore possible without problems. In the week after inserting the coil, however, tampons should still be avoided, as the cervix is still irritated and tampons can lead to an increased risk of infection. Both with and without the IUD, you should always ensure that the tampons are changed regularly after a few hours in order to prevent infections.
