These methods include intrauterine system (IUS / hormonal coil), contraceptive injections, and implant. LARC methods are more than 99% effective to prevent pregnancy. This means only 1 woman out of 100 using this method will get pregnant. These methods are very cost effective considering the duration for which they offer protection.
This article contains details about all four long-acting contraception methods (LARC) and how to avoid pregnancy effectively using these methods.
Intrauterine devices or simply an IUD is a small piece of flexible plastic and copper wrapped around it and looks like a letter T with two threads at one end. IUD is also known as an intrauterine contraceptive device (IUCD or ICD), contraceptive coil, or copper T. There are different types of IUD (copper T) mainly categorized based on the amount of copper and surface area exposed. IUD is the most used contraception methods for family planning. This long-acting and reversible contraception (LARC) method is popular due to its effectiveness to avoid pregnancy, the peace of mind and privacy it offers. The major advantage is that you do not need any on-going effort or attention to avoid pregnancy. That's the reason, sometimes it is also referred as "fit and forget" contraception method. Once removed, even after long-term use, fertility returns to normal condition rapidly.
Copper T is inserted into the uterus or womb with the two threads hanging through the cervix into the top of the vagina. It releases copper ions and changes the fluid inside the womb and fallopian tubes to make it hard for sperms to survive there. Although IUD decreases the absolute number of sperm cells that reach the egg, in some cases few sperms may reach the egg and fertilization may happen. To avoid pregnancy in such cases, IUD stops the egg from attaching to the wall of the uterus and prevent pregnancy.
Copper T is one of the most effective contraception methods with more than 99% effectiveness. It means only 1 out of 100 women using IUD has a chance of getting pregnant. They are so effective because you need not take any efforts to remember to use it and practice to use it correctly. One limitation of Copper T is that it does not offer protection against sexually transmitted diseases. You need to use condoms to prevent STDs. You also need to consult the doctor to insert the IUD.
IUD / Copper T is perfectly safe for most of the women but there are some conditions that may cause side effects or complications. Using IUD might not be safe if you have certain STDs, cervical or uterus cancer which is not treated if you have a pelvic infection or you are allergic to copper. Consult the doctor to find out if IUD is safe for you. It is very rare to get pregnant while using IUD, but if you get pregnant, make sure to get copper T removed as soon as you find out about your pregnancy. If you get pregnant with IUD in place, there is an increased risk of ectopic pregnancy and other serious health problems. That's the reason why you need to consult the doctor in case if you get pregnant while using IUD.
