It remains in place as long as contraception is desired: between 5 and 10 years depending on the model.

Used by nearly 150 million women worldwide, IUDs are the least expensive temporary contraceptive method for long-term use. In France, the IUD is the most used contraceptive method after the pill.

Since the early 1960s, when IUDs were made from inert materials, these devices have seen many improvements, including the use of copper.

How does the copper IUD work?

The copper-bearing IUD is indicated as an alternative method of contraception to chemical contraceptives, including oral hormonal contraceptive methods, to prevent their short-term or long-term adverse effects.

Its mode of action:

As soon as it enters the uterus, the IUD prevents the risk of pregnancy on two levels:

  • The IUD causes an inflammatory reaction (normal and non-infectious) of the uterine lining, which prevents implantation of the egg.
  • Copper, naturally spermicidal, prevents the spermatozoa from fertilizing an egg.

The copper IUD can also be used as emergency contraception after unprotected intercourse, provided that the pose does not occur more than 5 days after intercourse.

article-imageContrary to popular belief, there is no contraindication to the insertion of an IUD in a nulliparous patient .

The existence of two sizes: SHA called “short” and “standard” STA, for most copper IUDs is therefore justified because a childless woman whose uterus is smaller can be properly placed an IUD .

A “short” model can then be prescribed.


How is an IUD inserted?

The pose is done during the first part of the cycle to avoid inserting an IUD into a woman who may be pregnant. Prior to placement, hysterometry may be useful to evaluate the shape, size and sensitivity of the uterus. In principle, the insertion of an IUD is not very painful. Women who have never had a pregnancy, to the extent that the risk of pain is higher, can take an antispasmodic 2 hours before the pose. The pose itself is very fast. It lasts a few minutes.

A small sanitary napkin can be used because small bleeding can occur a few hours after insertion. For possible stomachaches, taking paracetamol relieves quickly.

It is useful to check annually during the gynecological surveillance visit to ensure that the IUD is well positioned. After 5 years, it is possible to remove the IUD and put a new one in the same consultation.

The copper-bearing IUD has the advantage of being very effective, having a long duration of action and presenting no cancer or cardiovascular risk.


Some contraindications to its pose exist however:
• Unexplained uterovaginal bleeding
• Pregnancy suspected or proven.
• A malformation of the uterus incompatible with the insertion of an IUD
• The antecedents or the existence of uterine or trophoblastic pathologies
• Situations at risk of infection (STD, high genital infection …)
• An allergy to copper or another of IUD components
• Postpartum (48 to 4 weeks);


IUDs are very effective. They are more than 99% effective. Since handling errors do not occur outside the time of insertion, the effectiveness of this method of contraception does not depend on the user, unlike the use of pills. Copper IUDs are effective from the day of insertion. They can be asked up to 5 days after the theoretical date of ovulation, the 19th day of the cycle. In ordinary conditions of use, IUDs maintain their performance where the failure rate of oral contraception rises to about 8% due to missed pill, digestive disorders … etc. Used as emergency contraception, the copper IUD is a very effective alternative to the morning after pill.

· Simplicity: you do not have to think about your pill every day
· Comfort: effective from the moment you set it up, immediately withdrawn back to previous fertility.
· The absence of hormones: health benefit
· The duration of use: tranquility for 5 years.

· Copper IUDs can lengthen and increase menstruation. If the rules are short and scarce, the difference will be imperceptible.
· Sometimes pain occurs at the time of menstruation or at the time of ovulation.

The rule:
“If you notice anything abnormal, ask your doctor for advice. “

it as first-line contraception including women without children and very young women.Close up on this method of contraception with multiple advantages.

What is an IUD?

An IUD is a small, flexible plastic contraceptive device that is slipped into the woman’s uterus. It is most often T-shaped. At its bottom end is two wires allowing the doctor to remove it very easily.
There are two types of sterilets: copper IUDs , equipped with a copper wire fixed around the central axis and hormonal or progestational IUDs, having a reservoir containing the hormonal active on the longitudinal part.

What is the action of the IUD?

The IUD provides young women with temporary or durable contraception, which is 99% reliable and much less restrictive than the pill. Once placed, a copper IUD can remain in place between 5 and 10 years against 3 to 5 years for a hormonal IUD. The operation of the IUD is simple:

  • Copper is naturally spermicidal (s) thus preventing sperm from reaching up to the fallopian tubes. In addition, the intrusion of a foreign body into the uterus causes an inflammatory reaction of the uterine lining (normal and non-infectious reaction), preventing implantation of the egg.
  • Hormonal IUDs combine two effects: the inflammatory response and the contraceptive effect. The progestogen hormone contained in the reservoir is released regularly in small amounts to act on the uterine lining.

Contrary to popular belief, the IUD makes absolutely no sterile. He is very badly named and many health professionals prefer the name of “intrauterine device” (IUD).

The risk of infection related to the IUD is not zero, but it is rare. The information of the patient and the follow-up by a professional make it possible to limit the risks. An IUD should always be placed and removed by a health professional.

What are the advantages and disadvantages of the IUD?

8 misconceptions about IUDs

There are quite a few misconceptions about IUDs (Intra-Uterine Devices): they come mostly from the time when this means of contraception had not been significantly studied, as is the case today. In addition, certain prejudices, such as “do not put an IUD in the nulliparous”, are specifically French. In other countries such as Belgium, for example, this practice is in common use. It is therefore important to clarify certain beliefs.

1. Sterilets … as infertility ??

FALSE – This term is old but still commonly used to refer to intra-uterine devices. The IUD is a totally reversible contraception. The delay in fertility recovery following removal of the IUD is comparable to that observed for oral contraception, that is to say immediats.

2. IUD in the Nulliparous?

TRUE – The IUD is a contraceptive recommended in first intention by the High Authority of Health. The most suitable model for the nulliparous is the 7 MED 380 USHA or NSHA (short size). The often low observance in the nulliparous young woman (under pill) is thus optimized.

In nulliparas, the expected benefits should be weighed against the potential therapeutic risks. For young women, the main risk is related to Sexually Transmitted Infections, especially in the case of multiple partners.

Only the condom protects against this risk.

3. NSAIDs and decreased efficiency?

FALSE – No decrease in efficacy with anti-inflammatories and any other medication. It is perfectly legitimate to prescribe an anti-inflammatory drug for a woman wearing an IUD (whether copper or levonorgestrel). (Thonneau study, Human Reproduction 2006).

On the other hand: non-steroidal anti-inflammatory drugs can only be used in short treatment.

In short treatment, they do not influence the contraceptive efficacy of IUDs

4. Emergency contraception?

TRUE – The action of the IUD is more effective than that of the pill in a period of not more than 5 days.

NB: Only copper IUDs should be inserted in this context , hormonal IUDs (Levonorgestrel) do not have this indication.

5. Ectopic pregnancy?

FALSE – The rate of ectopic pregnancies with the IUD is 0.02% per year. It is significantly lower than that of women not using contraception.

6. IUD: Is its size embarrassing?

 FALSE:  The IUD is an effective contraceptive but its supposed large size causes patient reluctance …?! Judge for yourself …….


7. Is the IUD sometimes the partner …?

FALSE – this is often a subjective feeling because penile sensitivity is relatively low. The wire connected to the IUD is cut short enough (2 to 3 cm from the external hole of the neck) so as not to generate the partner.

8. Does tobacco prohibit certain contraceptive methods?

TRUE – But not the insertion of an IUD: on the other hand, the combination of tobacco and hormones (the pill) is systematically avoided in the face of a greatly increased cardiovascular risk.
