What is an Intrauterine Device (IUD)?
An intrauterine device is a small, T-shaped plastic device that is inserted into the uterus to prevent pregnancy. The IUD may contain either copper or a synthetic hormone called progesterone, both of which work to inhibit conception.
How Do IUDs Work?
The progesterone-releasing IUD continually emits a low dose of synthetic hormone throughout the day. Both the copper IUD and the progesterone IUD prevent pregnancy in two primary ways:
- The release of progesterone or copper alters the cervical mucus and creates changes within the uterus, which either kills sperm or renders it inactive.
- The IUD modifies the uterine lining, making it less receptive to implantation should fertilization occur. It’s essential to consider the ethical implications of this method of prevention.
How is an IUD Used?
Before inserting the IUD, your healthcare provider will conduct a pelvic exam, a Pap smear, and possibly tests for sexually transmitted infections. The IUD is then placed through the vagina and cervix into the uterus by your medical professional. A follow-up appointment is typically scheduled two to three months after insertion. Unless there are issues or it’s time for your annual check-up, you won’t need to see your doctor again until it’s time to remove it. Depending on the type, an IUD can remain effective for five to ten years. It’s advisable to check the threads after each menstrual cycle to ensure the IUD is still in place—avoid pulling on the threads.
How Effective are IUDs?
IUDs boast a failure rate of less than 1%, meaning fewer than one in a hundred women get pregnant during the first year of use. If you experience any pregnancy symptoms, it’s crucial to take a pregnancy test.
What are the Side Effects or Health Risks of IUDs?
While IUDs are generally safe, there are several side effects and health considerations to keep in mind:
An IUD is not suitable for women who:
- Have a history of cervical or uterine cancer
- Experience unexplained vaginal bleeding
- May be pregnant
- Have pelvic inflammatory disease
- Have a history of ectopic pregnancy
- Have gonorrhea or chlamydia
- Are not in a mutually monogamous relationship
Possible side effects can include:
- Mood swings
- Acne
- Headaches
- Breast tenderness
- Pelvic pain
- Cramping (especially with copper IUDs)
- Increased menstrual bleeding (copper IUD)
- Nausea
Women with multiple sexual partners may face a higher risk of pelvic infections.
Are IUDs Reversible?
Absolutely. Once an IUD is removed, your ability to conceive returns rapidly, often within a month after removal.
What is the Cost of an IUD?
There are three costs associated with using an IUD: the doctor’s visit, the IUD itself, and a follow-up appointment three months later. Overall costs can range from $175 to $400, depending on the consultation fees.
Do IUDs Protect Against STIs?
IUDs do not provide protection against sexually transmitted infections.
