What is the intrauterine contraceptive device?

Intrauterine contraceptive devices are small t-shaped devices which are inserted into the uterus so as to prevent pregnancy. The shape of the device is congruent with that of the uterine cavity. So it sits snugly within the uterus. Depending on the type of intrauterine device, it releases various substances into the uterine cavity at very slow rates.

Intrauterine contraceptive devices are reversible forms of contraception, which means that the fertility of a woman in her reproductive age is restored on removing the IUD. It is also a long-acting contraceptive and can be used for a period of 5-10 years depending on the type.

If you are trying to make a choice between the different types of intrauterine contraceptive devices available, some information regarding each of them would be of great help.

It is in the form of a t-shaped frame that is wrapped with a copper wire. It is approved for use for a period of 10 years from the time of insertion, beyond which it has to be replaced with a new one.

It acts by reducing sperm motility, inhibiting transport of ovum and sometimes by damaging the sperm or ovum.

They have a hormone reservoir containing levonorgestrel. The most popular variety is known by the name Mirena and releases about 20micrograms of hormone per day. It is approved for use for about 5 years. There are various other brands of hormone-releasing IUD’s available in the market and the approved duration of use is specified for each of them by the manufacturer.

Though an IUD can be inserted at any time during your menstrual cycle, provided pregnancy is ruled out by urine pregnancy test, one may want to know if there is any specific time which is best suited for IUD insertion.

When is the best time for IUD insertion?

Ideally, IUD insertion should be done during the first 7 days of the menstrual cycle to decrease the possibility of pregnancy occurring during the same time.

Copper T is effective from day 1 of insertion and for the same reason, no backup contraception is needed following insertion.

IUD can also be inserted immediately following spontaneous or elective abortion.

If you have recently delivered a baby and are considering copper T as an option for contraception, you may be wondering about how early you could get a copper T  inserted.

Time of IUD insertion after delivery

The safety and effectiveness of IUD insertion during the immediate post-delivery period, i.e even within 10 minutes of delivery has been proven by several studies. Immediate post delivery insertion of IUD is possible following both vaginal and cesarean delivery. If the woman has chorioamnionitis or endometritis, IUD should not be inserted immediately post delivery.

IUD removal and replacement:

Just as with the insertion of IUD, it is possible to remove the IUD at any point during your menstrual cycle. But it may be easier and less painful to remove the IUD during your period as the cervix becomes naturally soft while you are menstruating.

Can IUD be used as emergency contraception?

Yes, copper T IUD can be used as an emergency contraception. Copper T has to be inserted within 5 days of unprotected sexual intercourse so as to prove effective in preventing pregnancy. The copper released from the IUD prevents the implantation of the embryo within the uterine lining and is the most effective form of emergency contraception.

As you are preparing to get an IUD inserted you may want to be informed of the possible complications.

Complications of the intrauterine contraceptive device are :

How to prepare for IUD procedure?

The woman needs to be evaluated in detail by a gynecologist prior to IUD insertion. A detailed counseling should be done and informed consent obtained. No anesthesia or analgesia is needed for IUD insertion procedure. Mild pain and discomfort during insertion are to be expected.

Post IUD insertion care:

Following IUD insertion, women are expected to follow up after 4 weeks. During the follow-up visit issues are discussed if any and an examination is done to confirm the IUD strings are visible extending from the cervical opening.

If the strings are found to be absent, the possibility of IUD migration and unrecognized perforation needs to be considered and evaluated in detail.

Can I get pregnant with IUD?

Though the efficacy of IUD is comparable to sterilization, as in any form of contraception there is some risk of failure. The failure rate of IUD is about 0.2%-0.8%. If pregnancy occurs with IUD in place it is more likely to be an ectopic pregnancy. Intrauterine pregnancies that continue with an IUD in place are associated with high risk of complications such as spontaneous abortion and septic abortion.
