Intrauterine hormonal system

Intrauterine hormonal system

Modern medicine can not only cure different diseases, it can also do other useful things. For example, intrauterine hormonal system (or IUS) can prevent a woman from getting pregnant.

It’s a very small device, its form resembles a letter “T”. It’s made of a very soft plastic material. A doctor puts this device into a woman’s uterus, but she won’t feel the presents of IUS. The effect lasts for several years – from three to five. One of the biggest brands which is preferred by most women is Mirena.

How the system works?

As it was mentioned, the system is T-shaped and it is made of a very soft plastic. It’s 100% comfortable, women don’t feel this system. It is very similar to another intrauterine hormonal system – IUD. The difference between these two systems is that IUS contains hormone progestogen, while a IUD device contains nonhormonal substance, called copper.

So how is it possible, that such a small device can prevent a woman from becoming pregnant? The system releases progestogen which prevents disables sperm from migrating into woman’s cervix. Because of this particular feature of the hormone, the system gives a 99% guarantee that a woman won’t get pregnant.

In some cases, the progestogen hormone effects the egg – it is not released each month, as usual. This means that a woman does not ovulate each month. But such cases are rare and usually it only affects the sperm by thickening the cervical mucus. In this case the sperm can’t reach the egg in order to fertilize it.

It’s important that the system is inserted correctly by a qualified doctor since only in this case there is 1% chance of a pregnancy. It’s also advised to use only reliable brands, such as Mirena. In the catalog of Mirena products on women can find options that would fit their lifestyle.

Mirena cost is acceptable, so anyone can buy it. There you can also find out how long does Mirena last. Most of the systems last maximum of five years, guaranteed full three years. Mirena reviews show that the system is effective and protects women from unplanned pregnancies.

What women should know about IUS – interesting facts

Some women are still debating on whether they should or should not use such a system to prevent unplanned pregnancy. Most still use traditional contraceptive methods. But IUS is one of the best ways, if not the only, to prevent a woman from getting pregnant during such a long period.

Oral contraceptives are unreliable because if you forget to drink a pill or use it with other specific medicine, the effect can be weakened which might result in pregnancy. Condoms also have disadvantages since people may be allergic to the material which is used to produce condoms. And as in the case of oral contraceptives, people should never forget to use them.

At the same time, it is still advised to use condoms even if you have an implanted IUS or IUD device. The system will protect you from unwanted pregnancy, but not from STDs and other similar diseases.

Let’s check out some facts which could help you understand more about how this system works:

  • Only a doctor should implant it. If it’s implanted improperly, it won’t guarantee the 99% effectiveness.
  • Only a doctor or a nurse can take it out, so it is advised to visit a doctor when the system is almost expired. Be careful, it’s possible to get pregnant immediately after the system is taken.
  • It helps women with painful periods. It stops them or lightens the painful effects.
  • It’s comfortable. The moment a doctor places it, you just forget about it.
  • But it may affect woman’s mood, or cause some minor skin problems – because of the hormone.
  • It is advised to implant the system in the middle of period. In this case, when a woman is experiencing period, doctor can be sure that she is not pregnant. But it’s not a rule, and you can implant it whenever you prefer, as long as you are not pregnant.
  • This system is not protecting women from sexually transmitted infections. It’s always a good idea to use condoms, even if you use a system, or if you prefer oral contraceptives.
  • The procedure can be a bit painful for women, but doctors can use painkillers in order to reduce those effects.

It is also recommended to use condoms a while after the system was inserted. Only if IUS was placed during first seven days of your cycle, the woman immediately gains protection. But if it is placed in any other time, it is advised to use condoms during seven days after the system was implanted.
