What is Mirena Intrauterine Device?

The vertical bar of the device contains a capsule with 38 mg of the levonorgestrel hormone with barium chloride sprayed in silicone that actually works to prevent pregnancy.

To perform its function, Mirena IUD is placed inside the uterus, where it can stay up to 6 years. Mirena insertion can be performed only by a professional OB-GYN doctor in premenopausal female patients who do not have any contraindications to use hormonal IUD. Also, after the insertion, the woman should undergo a medical examination with the gynecologist at least 1 time in a year to make sure the device did not move from its place, there are no infections and other medical conditions.

One more benefit of using Mirena intrauterine contraception is that it can be removed at any time per the patient’s request. We stress once more that only a professional doctor can remove and insert the IUD. No way to do it yourself at home. It can be dangerous to your health.

Mirena Removal and Insertion

If there are no reasons to cancel the procedure, the doctor can start inserting Mirena. The technique of hormonal IUD insertion differs from that with the introduction of conventional IUDs due to the large diameter of the device due to the presence of a reservoir with a hormonal drug. Therefore, cervical dilatation and local anesthesia are sometimes required. The LNG-IUD can be inserted at any time during the menstrual cycle, after an induced abortion in the first trimester (immediately after surgery), or 6 weeks after childbirth. The first control examination is carried out after 1 month, then – after 3 months, and then – once a year.

The process of the insertion or removal should not cause excessive pain, severe cramps, excessive bleeding, although it may feel painful and uncomfortable.

When the procedure is done, the patient can go home immediately as there is no reason for hospitalization.

Is Mirena Safe for Health?

We have already discussed the contraindications that do not allow insert Mirena. Otherwise, it may lead to problems with health and possible side effects that may accompany this birth control method. If the doctor is a real professional, you will be able to avoid many complications like pelvic inflammatory disease, infections, genital lesions, etc. But as long as this IUD contains hormones, the question of the safety of using Mirena is still open. Especially many women are interested in whether it will not affect ovulation and the woman’s ability to get pregnant.

The answer is that it indeed has an impact on menstruation cycles, and in the first few months, the patient may experience heavier bleeding or no periods at all. It is individual. But when this period passes, everything comes to the norm., and the bleeding starts to occur much rarer. In women with normal menstrual function, the number of days of bleeding decreases, and after 1 year, it can be 1 day. With menorrhagia, after 3 months, the volume of blood loss decreases by 86%, after 1 year – by 97%. By the way, using Mirena is approved to treat heavy menstrual bleeding.

So, does your amenorrhea renews when you remove Mirena, and how fast? Of course. It may take up to 12 months for your organism to renew its function of menstruation and ovulation, and after that, you will have chances for normal pregnancy.
