Intrauterine System



The T-shaped contraceptive device which is made up of plastic, which is placed inside the uterus, is termed the intrauterine system. The intrauterine device and the intrauterine have similar shapes. This device stimulates the release of progesterone into the woman’s body.

The cervical opening will have two fine threads coming out of it where as the rest will be present on the vagina’s top. This is normally inserted during the menstrual periods or just after it.

If the intrauterine system is fixed during the first five days of menstrual cycle of a woman, then the protection against pregnancy is immediate. If it is inserted in other conditions, then she may have to use additional methods of contraception for one week. A woman who uses an intrauterine contraceptive system will be protected from being pregnant for about ninety nine percent.

The intrauterine system is effective for almost five years.

How does an intrauterine system work

The sperm is prevented from reaching eggs. The progesterone which is released by the intrauterine system causes the thickening of the mucus which is present in the cervix.

The lining of the womb of the woman is made thin to such an extent where it rejects the fertilised egg. But in certain cases, the ovulation itself will be absent. In normal cases, even after the insertion of intrauterine system the women ovulate.

Use of an intrauterine system

The use of intrauterine system is similar to using any other method of contraception which is of a non-barrier nature. Intrauterine system is a reversible contraceptive method which has proven to be effective in almost ninety nine percent of the cases. But a woman is not protected against the infections and diseases that are transmitted sexually.
