What to Expect With an IUD: Your Questions Answered on Sex and Safety

After becoming a parent, whether for the first time or the fifth, many women decide they’re finished having children—at least for the time being. The reassurance of preventing unplanned pregnancies is invaluable. One of the most popular contraceptive methods is the IUD (intrauterine device), a T-shaped plastic device roughly the size of a quarter that is placed in the uterine lining. An IUD can be inserted at any point during your cycle, even right after childbirth. According to studies, among 100 couples using an IUD, fewer than one will experience an unintended pregnancy.

IUDs are a preferred choice for long-term contraception due to their effectiveness and convenience. Unlike birth control pills, there’s no need to remember daily doses, and the risk of incorrect use, like with condoms, is eliminated.

You might have some burning questions:

Can my partner feel the IUD during sex?
Is it possible for an IUD to come out during rough intercourse?
What signs indicate that an IUD is out of position?

Let’s dive into these concerns and more.

Hormonal vs. Non-Hormonal IUDs

Understanding how an IUD affects your body is crucial. There are five FDA-approved brands, categorized into two types:

Hormonal IUD: This type releases the hormone progestin (similar to progesterone) to prevent pregnancy. Depending on the brand, it can last three to seven years. Hormonal IUDs work by thinning the uterine lining to inhibit egg implantation and thickening cervical mucus to block sperm. If you experience heavy or painful periods, this type may lighten your flow.
Copper IUD (Non-Hormonal): Designed to last up to 12 years, this option avoids hormones, making it suitable for those who have adverse reactions to them. The copper wire surrounding the device damages sperm, making fertilization nearly impossible. However, it may lead to longer and more painful periods, which could affect your libido.

The insertion of an IUD can be uncomfortable or even painful for some, often accompanied by cramping. Once inserted, sex can resume, but sensitivity in the area may linger.

The Strings: What to Expect

Your partner generally won’t notice the IUD during intercourse. After insertion, one or two thin plastic strings, resembling fishing line, extend into the vaginal canal. Occasionally, the tip of the penis may brush against these strings, which some find uncomfortable.

If this happens, don’t worry! Such sensations are normal. The strings typically soften and curl around the cervix within a few weeks. If they pose an issue, consider these tips to enhance comfort:

Have your partner wear a condom.
Encourage shallower thrusting.
Consult your doctor about trimming the strings, though be aware this might create sharper edges.

What About Rough Sex?

If you and your partner enjoy more vigorous sexual experiences, you might wonder, “Can an IUD dislodge during rough sex?” According to the American College of Obstetricians and Gynecologists, IUD expulsion can happen in 2 to 10 percent of users, varying by type. However, it’s not common for an IUD to fall out entirely, and rough sex isn’t typically a contributing factor. The risk of expulsion is highest shortly after insertion, especially if the device was placed incorrectly or if your body rejects it. As time passes, the likelihood of it moving decreases.

Signs of IUD Movement

While an IUD usually remains in place, it can sometimes shift. If you suspect this, reach out to your gynecologist for evaluation. Signs to watch for include:

Intense pain: If you experience severe discomfort outside of your menstrual cycle, it may indicate a problem.
Feeling the IUD in your cervix: You shouldn’t feel the IUD at all. If you do, seek medical attention.
Changes in string length: Use clean hands to check the strings. They should be felt at the cervix; if they’re longer or shorter, the IUD may have shifted.
Painful intercourse: If sex becomes painful, it could signal a shift in the IUD or another issue, like endometriosis.

Most individuals with IUDs face no complications, and if movement occurs, your doctor can assist you. Whether you’re done having kids for now or permanently, an IUD is an excellent birth control option for many women.

Can Your Partner Ejaculate Inside You With an IUD?

An IUD is designed to create an environment within the uterus that’s hostile to sperm. However, it doesn’t prevent semen from entering the vagina. There’s still a slim chance—around one percent—of pregnancy even when using an IUD.

Do IUDs Cause Weight Gain?

Some women may experience weight gain with an IUD, particularly hormonal types. This can occur due to progestin-induced water retention. Common side effects also include bloating, acne, spotting, and mood fluctuations.

What Should You Avoid After Getting an IUD?

After insertion, it’s advisable to refrain from sex, swimming, bathing, or using tampons for at least a day or two. The risk of expulsion is higher during the initial weeks. While strict bed rest isn’t necessary, it’s wise to avoid strenuous activities for a couple of days.
