Implanon - Sub-dermal Contraceptive

Among lots of available methods of contraception today, there is one that is a great example of a science progress. A 12-years research and tests resulted into an introduction of a new method in 1998. That was the launch of Implanon, a sub-dermal contraceptive implant.

This 4cm x 2mm contraceptive device contains 68mg of a synthetic progestagen, etonorgestrel. The hormone is slowly released into the blood pleasure in the amount of 40 micrograms daily. The mechanism of action is that similar to the oral contraceptives based on hormones. Etonorgestrel inhibits ovulation and increases the thickness of the cervix, preventing the sperm from penetration into the womb.

The procedure of implantation is quite easy and is made under the local anaesthetic directly under the skin of the inner aspect of the upper arm (non-dominant, as a rule). The procedure should be performed by the professional who attended special training. So that should be discussed with the doctor beforehand. The sign of a successful insertion is the palpability of the rod. Implanon is the most effective if inserted on the 1-5 day of the menstrual cycle.

Three years is the time you don’t have to worry about other contraception options – this is the time Implanon keeps preventing ovulation. If the weight index of a woman exceeds 35 kg/m2 the time of removal will be earlier, because the effectiveness of the implant may decrease.

This method of contraception should be especially favored by those women, who have contradiction to oestrogen, since Implanon, unlike most of the birth-control pills, contains synthetic progestagen only. Also, it is just was created for you if you are the person who keeps forgetting to do the daily routine (not only to water your flowers, but also to take your pill). Having the thingy that will work for you is a convenient contraception method.

Since Implanon doesn’t contain oestrogen, the menstrual cycle may be erratic, though the number of days of bleeding decreases. Among other side effects you may notice fluid retention, breast tenderness, some weight gain, mood change, headache, acne (although sometimes pre-existing acne is treated with Implanon), hair loss or growth, ovarian cyst and some more individual symptoms which should be the reason to talk to your doctor.

At the site of implant some bruising or irritation may occur, which naturally comes off in a couple days. It is recommended to see your doctor to check the blood pressure in a couple weeks after Implanon insertion.

Women with diabetes, breast cancer and history of severe liver disease should chose for themselves other methods of contraception, since Implanon is not recommended for individuals with those conditions.

Removal of the rod can be performed at any stage. Local anaesthetic and a tiny cut in the skin make up the procedure. In a couple weeks women restore their fertility.

After the three years of being your protective friend, Implanon easily gives you the way to get a chance of pregnancy. (If you decide you are done with progressive contraception and want to become a happy mom.)
