Few Forms of Long-Term Contraception

There are few forms of long-term contraception that can prevent women, which already gave birth, from another unexpected pregnancy. As we all know there are various types of contraception, which are suitable for different periods of our lives. For example young women and girls that are sexually active, short-term forms of contraception that usually don’t affect the reproductive system like condoms or birth control pills. Unlike them, older women who have decided to take a break between each delivery or maybe they have decided that they don’t want children any more can use forms of long-term contraception.


This is a radical form of long-term (definite) contraception and every woman that considers this option should understand that there is no turning back after the procedure is done. Sterilization is good because it doesn’t affect the sexual life at all and there is no need for other contraceptive measures. Women should remember that attempt to reverse this process by trying to re-establish the patency of fallopian tubes is very risky and complicated surgical procedure that is not always successful. That’s why doctors suggest that women who want to take this procedure should be well informed about other long-term methods of contraception, that can be also very effective but unlike sterilization they are not permanent.

Hormonal intrauterine systems

These systems contain a reservoir with progestogen hormone, which releases a small dosage of the hormone in the womb every day. With the help of this hormone, the mucus in the cervix is thickened so the passage of sperm into the uterus is blocked. Even if some of the sperm has managed to get inside the uterus the normal movement will be difficult. Due to its local affect on the uterus it also reduces the overgrowth of the lining of the uterus. Furthermore this makes the menstruation milder, shorter and even less painful and in some cases women using this type of contraception don’t have menstruation at all. Besides that this systems can prevent infections in the pelvic area and occurrence of endometrial cancer. Because it acts locally the hormonal balance in the body is preserved and there are no side effects. These hormonal systems can be implanted six weeks after birth and mothers who are breast feeding their babies should not be worried because these hormones don’t affect the milk. Hormonal intrauterine systems are almost 100% effective, they last for five years and they can be easily removed if needed.

Copper-based intrauterine devices

These devices are similar to the hormonal systems in their appearance and they are a well known and recognized method of long-term contraception. They are made of copper and plastics and what makes them different from the previously mentioned devices is that they do not contain hormones. They work in a simple way by disabling sperm on their way to the fallopian tubes and make the connection between sperm and eggs impossible. They can last from three to ten years, depending on the type of the device. These devices are more than 99% effective. They are not recommended for women that have not yet given birth or anemic women because sometimes they cause longer and more intensive menstruations.
