The very structure of Norplant is relatively complex -- it includes six flexible implants that are plastic and very thin. The size of each of the implants is similar to that of cardboard matchstick. The essence of Norplant insertion implies that the constituent elements of the birth control device are placed under upper arm skin. Each component of Norplant has in its chemical structure a certain amount of progestin levonorgestrel. The very activity of Norplant lies in the fact that the hormone is constantly released into the blood. To give you an idea of how progestin works, it is sufficient to say that it is a hormone similar to progesterone. Only the former is synthetic and the latter is naturally produced by he lady's ovaries.
The activity of progestin in the woman's body is two-fold. Firstly is influences the consistence of the mucus in such a way that it becomes harder and therefore impenetrable for the sperm, which prevents the latter from reaching the egg and joining with it. Another way in which progestin could influence the natural processes in the female body is stopping the ovaries from ovulation. When it comes to the efficiency of this birth control method, mention must be made of the fact that it is second only to continuous abstinence. The statistics speak volumes about the absolute efficacy of this birth control method.
Out of 10 000 ladies who have resorted to Norplant usage only five have become pregnant. In these cases the pregnancy occurred during the first year. It is curious to note that Norplant has a potential of eliminating the risk of pregnancy for about seven years. What has to be borne in mind by overweight ladies is that the Norplant efficiency diminishes for them after about five years. It is advisable that upon expiry of this time period they consult their doctors to discover if they can continue the usage of the Norplant. He may suggest another option, taking into the consideration the possible Norplant side effects.
The very process of Norplant insertion is far from being complicated. After the thorough physical exam you are administered a pain killer in order to make the small arm area numb. Then a small cut is made. Six capsules are put under the arm skin. In this case the least used arm is selected. The whole procedure takes up to ten minutes. Within about 24 hours the protective function of progestin is released. Besides the medical history, you have to inform the doctor of any chance of pregnancy at the time of Norplant insertion. Normally a follow-up visit is recommended within three months after the insertion.
The best rate of follow-up visits is on a yearly basis. Should you address some other doctor for some health issues, it is crucial that you tell him about the Norplant usage. After a period of about seven years Norplant has to be removed, as it loses its efficiency and may lead to menstrual irregularities. It is also possible to remove it before the above-mentioned term expires.
The Norplant removal procedure is to a great extent similar to the insertion procedure. Through a small cut in the numb area the six capsules are removed. The whole procedure takes up to half an hour.
