IUD vs. Mirena

Difference Between IUD and Mirena

To ensure the necessary family planning, many couples have used a variety of different types of contraceptives to prevent fertilization of the egg by the sperm during sex. IUDs are one of the more favored methods of birth control that are used by many women today. Compared to other methods of birth control, IUDs are able to prevent 99% of pregnancies for longer periods. In many cases, women who use IUDs are protected from 1 to 10 years.

The IUD is made of a soft plastic that is inserted into the uterus to prevent sperm from reaching the egg, as the IUD blocks the uterus. It also prevents the egg to attach itself to the wall of the uterus in case fertilization that normally occurs during sex. In some cases, the IUD also contains a fine lining of copper wrap over plastic, making it much sturdier. With due care in its insertion, an IUD can prevent pregnancy for up to ten years. In fact, the IUD works as good as if a woman had a ligation operation, except that in the case of IUD, the woman can still get pregnant by simply removing the IUD device and no surgery is required to insert the IUD.

The Mirena contraceptive system is very similar to the IUD, which consists of a device that is inserted into the uterus to prevent fertilization of the egg, as well as the planting of the fertilized egg in the uterine wall if fertilization occurs. One important difference between conventional IUDs and Mirena contraceptive system is that the Mirena also releases small doses of a synthetic form of progesterone called levonorgestrel, directly into the uterus. This hormone increases the effectiveness of the Mirena contraceptive because it causes a disruption in the menstrual cycle of women, by preventing ovulation from occurring.

Another important difference between the Mirena contraceptive system and conventional IUD devices used is their life. While most IUD devices can last up to ten years, the Mirena contraceptive system lasts for only half that time. It is mainly due to the fact that hormones released into the uterus reduces and needs to be replenished by inserting a new Mirena contraceptive device. Becoming pregnant after the use of the Mirena system can also be more difficult than using conventional IUD devices, because the reproductive system of women will need some time for it to return to its normal cycle.

Summary:

1. Both the IUD and Mirena contraceptive systems involves  inserting a device into the uterus to prevent sperm from coming into contact with the egg, as well as preventing the fertilized egg to grow on the uterus wall.

2. The Mirena also releases small dosages of synthetic progesterone in the uterus for further increase its ability to prevent pregnancy.

3. The IUD has a longer life than the Mirena, as it can be effective up to ten years, compared with the Mirena that only has a lifespan of five years.
