Ring, it is me – Mirena Ring.
Is it very literary to hear my name? Listening to those “stainless steel rings”, “T copper rings”, “V-rings” and “γ-rings”, does it make people feel afraid?
I am not only beautiful in name, but also incomparable with other traditional contraceptive rings. The price is not low (it needs more than 1300 yuan) – the “white rich beauty” of the standard contraceptive ring industry!
Who am I?
My full name is levonorgestrel-releasing intrauterine system (LNG-IUS).
I am from Bayer, Germany. My English name is Mirena, which was invented by a Finnish scientist Luukkainen.
My body is a plastic stent, 32mm long, there is a small tube on the longitudinal arm of the stent, which contains 52mg of levonorgestrel, which releases 20ug per day, Acting locally on the endometrium, it can be released continuously for 5 years (that is, the validity period is 5 years).
Levonorgestrel is a highly potent progestin. The sustained-release system releases levonorgestrel quantitatively every day, which continues to act on the endometrium, causing the endometrium to fail to proliferate and is no longer suitable for embryo growth.
How am I different from a traditional birth control ring?
It starts with pregnancy:<600"> span>The egg develops and matures in the ovary, and at the ovulation period (usually about 14 days before the next menstrual period), the egg is released and picked up by the fallopian tube into the fallopian tube cavity, where it meets and fertilizes with sperm to become a fertilized egg. At the same time, the endometrium thickens continuously under the action of estrogen and progesterone secreted by the ovaries, becoming soft and nutritious, waiting for the fertilized egg to implant. The fertilized egg reaches the uterine cavity about 1 week after fertilization, implants in the endometrium, and then takes root and sprouts.
Understanding this process, you will know to prevent pregnancy, that is, contraception, that is, 3 methods:
prevents follicle development and ovulation;
prevents sperm from meeting egg; p>
Prevent the implantation of a fertilized egg.
The traditional contraceptive ring is that after it occupies the uterine cavity, it produces some aseptic reactions, interferes with the implantation of fertilized eggs, contains The copper IUD also prevents the implantation of a fertilized egg and affects embryonic development through the biological activity of copper.
As for me, in addition to the role of the traditional IUD, I also release 20ug of levonorgestrel every day, which prevents the endometrium from proliferating, and the endometrium shrinks and thins , like a barren land, where fertilized eggs cannot be planted, and embryos cannot grow.
So, my contraceptive effect is better than the traditional IUD.
I also have another advantage, that is, my material is plastic, so after I put it on, I can do an MRI examination (the metal ring is not suitable for magnetic resonance imaging). resonance checked). My favorite is that it can also cure diseases! Now, more and more gynecologists use me to treat diseases, and even use me to treat diseases more than contraceptives!
I can cure diseases or it is because of the left Norgestrel, because levonorgestrel fights estrogen-induced endometrial hyperplasia, which causes endometrial atrophy and thinning.
Almost all are associated with estrogen stimulation I can treat all gynecological diseases.
Treatable gynecological diseases:
- < p>Anovulatory Abnormal Uterine Bleeding
Endometrial Hyperplasia
adenomyosis
endometriosis
uterine fibroids
menorrhagia
chronic pelvic pain
can significantly reduce menstrual flow, relieve dysmenorrhea, reduce Hysterectomy (before I did, many sick women needed to have their uterus removed). For anovulatory uterine abnormal bleeding and endometrial hyperplasia, it can prevent abnormal endometrial hyperplasia and canceration after being placed.
In addition, it can be used in menopausal hormone replacement therapy to replace oral progesterone to protect the endometrium.
Is the placement method the same as a traditional IUD?
The placement method is basically the same as other IUDs. Where the ring is placed in the uterine cavity
time of placement
Regular placement:Place within 7 days of menstruation, in order to prevent the lining of the uterus in time proliferation.
After miscarriage:Place immediately after surgery.
Postpartum:After 42 days postpartum, the uterus is ready for placement. Levonorgestrel is released in the uterine cavity, absorbs very little (only 0.2%) into the bloodstream, does not affect ovulation, and does not affect breastfeeding.
After diagnostic curettage, endometrial polypectomy: immediately after surgery place.
When treating adenomyosis, if the uterus is too large, more than 8 weeks of gestation, and the depth of the uterine cavity is greater than 9cm, drug treatment should be given first. Wait until the uterus shrinks before putting it back on. If the uterine fibroids are seriously deformed, they are not suitable for placement, and they are easy to ectopic or fall off after being placed.
There will be some side effects after putting it on, but don’t worry!
The most common side effect is irregular vaginal bleeding. Statistics show that in the first 3 months after placement, 2/3 of women will experience irregular bleeding, 11% of women will have oligomenorrhea, and 22% of women will have prolonged bleeding time; after 1 year of use Later, 57% of women will experience oligomenorrhea and 16% will experience amenorrhea.
What should I do? These side effects are caused by endometrial atrophy caused by levonorgestrel and have no effect on ovarian function. In other words, the ovaries will still work normally and secrete sex hormones normally, so it will not cause aging, and menstruation can return to normal after the ring is taken, and it will not affect fertility. So, there is no need to worry and no need for treatment. In addition to irregular bleeding, oligomenorrhea, and amenorrhea, some people also experience headache, abdominal pain, mood changes, edema, and acne, but the incidence is very low.
Finally, tell my female friends: I am not suitable for all women, Need to consult a doctor.
In the early stage after placement, most women will have irregular vaginal bleeding. Generally, after 1-2 years, most women will have very little menstrual flow. The pad is fine, some women will have amenorrhea, this does not affect health, do not take it out easily.
Place for 1 month, 3 months, 6 months, 12 months and review once, and then review once a year. Severe headache, jaundice, markedly increased blood pressure, or severe arterial thrombosis such as stroke or myocardial infarction should be removed promptly.
In addition, if you have any questions during use, you should consult your doctor for help.
