This medical device related article is a stub.

An intrauterine device (IUD) is a small, T-shaped contraceptive device that is inserted into a woman's uterus to prevent pregnancy. It is a long-term, reversible form of birth control and is considered one of the most effective contraceptive methods available.

Types of IUDs[edit]

There are two primary types of IUDs:

Copper IUDs – Such as ParaGard, which releases copper ions that create an inhospitable environment for sperm, preventing fertilization. Copper IUDs can also be used as emergency contraception if inserted within five days of unprotected sex.
Hormonal IUDs – Include Mirena, Kyleena, Liletta, and Skyla. These IUDs release progestin, a synthetic form of the hormone progesterone, which thickens cervical mucus to block sperm and sometimes suppresses ovulation.

Mechanism of Action[edit]

IUDs work primarily by:

Preventing fertilization by altering the uterine and cervical environment
Thickening cervical mucus (hormonal IUDs), making it difficult for sperm to reach the egg
Preventing implantation in the uterus through inflammatory changes in the endometrial lining
Acting as a spermicide (copper IUDs), making sperm inactive

Effectiveness[edit]

IUDs are over 99% effective, meaning fewer than 1 in 100 women using an IUD will become pregnant each year. Once inserted, they provide long-lasting protection:

Copper IUDs – Effective for up to 10 years
Hormonal IUDs – Last between 3 to 7 years, depending on the brand

Insertion and Removal[edit]

Insertion The IUD is inserted into the uterus by a healthcare provider, typically during an office visit. The procedure takes a few minutes and may cause mild to moderate discomfort. Some providers recommend taking pain relievers beforehand to ease cramping.

Removal IUDs can be removed at any time by a healthcare provider. Fertility typically returns quickly after removal.

Advantages[edit]

Long-term protection – Lasts several years depending on the type
Reversible – Fertility returns soon after removal
No daily maintenance – Unlike oral contraceptives, IUDs require no daily adherence
Highly effective – Low failure rate compared to other contraceptive methods
Can be used by breastfeeding women – Does not affect milk production

Side Effects and Risks[edit]

While IUDs are generally safe, they may cause:

Irregular bleeding or spotting (especially in the first few months)
Cramping and discomfort after insertion
Expulsion – In rare cases, the IUD may slip out of place
Perforation – In very rare instances, the IUD may puncture the uterine wall
Increased menstrual bleeding and cramping (more common with copper IUDs)

Contraindications[edit]

IUDs may not be recommended for individuals with:

Active pelvic infections (such as untreated sexually transmitted infections)
Abnormal uterine shape or fibroids that distort the uterine cavity
Unexplained vaginal bleeding
History of uterine perforation
Copper allergy (for copper IUDs)

History of IUDs[edit]

The concept of intrauterine contraception dates back to ancient times, but modern IUDs have been in use since the early 1900s:

The first widely used IUD was the Grafenberg ring, developed in the 1920s.
The Dalkon Shield, a now-defunct IUD from the 1970s, led to controversy due to safety concerns.
Modern IUDs, introduced in the 1980s and beyond, are safer, more effective, and widely recommended for contraception.

IUDs and Emergency Contraception[edit]

The copper IUD is one of the most effective forms of emergency contraception, reducing the risk of pregnancy by more than 99% when inserted within five days of unprotected intercourse.

Comparisons with Other Birth Control Methods[edit]

Method	Effectiveness	Duration	Hormonal
IUD (hormonal)	99%	3-7 years	Yes
IUD (copper)	99%	Up to 10 years	No
Birth control pill	91%	Daily	Yes
Condoms	85%	Single-use	No
Implant	99%	Up to 5 years	Yes

Common Myths About IUDs[edit]

1. "IUDs cause infertility."
- FALSE: IUDs do not cause infertility. Fertility returns quickly after removal.
2. "IUDs are only for women who have had children."
- FALSE: IUDs are safe for both women who have had children and those who have not.
3. "IUDs can travel to the heart or brain."
- FALSE: IUDs stay within the uterus and do not migrate to other body parts.
4. "IUD insertion is extremely painful."
- FALSE: While some discomfort is normal, most people tolerate the procedure well.
