Implanon in its essence is a single rod, which is non-biodegradable. Its length is about 40 mm and its diameter is about 2 mm. The Implanon insertion is quite a simple procedure. It is done by medical professionals with the help of a device specially intended for this procedure -- the applicator. Once placed under upper arm skin the implanon starts releasing the etonogestel, which is the special progestogenic hormone. Its chemical composition is close to that of oral contraceptive medications.
Both birth control devices contain desogestrel metabolite. To give you a notion of the Implanon itself it is sufficient to say that it is a flexible single sub-dermal implanted device. Among its major components are etonorgestrel and synthetic progestaen. The device is intended for insertion under local anesthesia. For insertion the upper part of the least used arm is selected.
Speaking about Implanon functions mention must be made of the following: the daily released amount of about 40 micrograms of hormone etonorgestrel prevents the ovulation, increases the mucus viscosity thus preventing the sperm from reaching the egg. Once the Implanon is removed the etonorgestrel level comes back to normal very quickly. The odds are that a woman will ovulate in the course of the first month after the implanon removal.
There is no denying the fact that Implanon is highly effective and convenient in comparison with other birth control methods. However, the essential conditions of Implanon effectiveness is the fact that it is inserted in the right time and in the right manner.
