Can IUDs make you infertile

Can IUDs make you infertile? Okay, let’s talk about the elephant in the room. Or rather, the little T-shaped device in your uterus that has been the subject of some seriously scary whispers.

You have heard the rumor. Maybe it came from a friend of a friend, a comment section rabbit hole, or an outdated anecdote from your mom’s generation. The fear is real, and it sounds like this: “If I get an IUD, am I going to mess up my chances of having a baby later?”

It is the number one reason people hesitate. You want control now, but you don’t want to pay for it with heartbreak later. That is a heavy trade off.

Can IUDs make you infertile? But here is the truth bomb you need to hear: No, IUDs do not make you infertile.

Let me say it louder for the people in the back. The intrauterine device (whether it’s the hormonal Mirena or Kyleena, or the copper kind) is designed to be reversible. In fact, the moment that little device comes out, your body basically shrugs and says, “Okay, let’s get back to work.”

Stick with me. Let’s tear down the science fiction and look at the science fact, so you can finally breathe easy.

The “Old School” Fear vs. The Modern Reality

We have to go back in time for a second to understand why this myth has legs. In the 1970s, there was a device called the Dalkon Shield. It was flawed. It caused serious infections, and yes, those infections led to fertility issues. It was a disaster, and it rightfully gave IUDs a bad rap for decades.

But that was then. This is now.

Modern IUDs are safe. The American College of Obstetricians and Gynecologists (ACOG) has been very clear: IUDs do not cause infertility or make it harder to conceive in the future . The risk of infertility after stopping an IUD is no higher than after stopping the pill or the ring.

So, how did the rumor survive? Usually, it is a mix up of correlation vs. causation.

Here is the honest breakdown. IUDs don’t cause infertility, but what does cause infertility? Untreated STIs.

If you have an undiagnosed sexually transmitted infection (like chlamydia) and you get an IUD inserted, the insertion process might allow those bacteria to travel up into your pelvis a little easier. That can lead to Pelvic Inflammatory Disease (PID). And PID? That is the real villain. PID can scar your fallopian tubes and genuinely cause infertility.

The takeaway: The IUD isn’t the problem. The untreated infection is. This is why responsible doctors test for STIs or assess your risk before insertion.

What Actually Happens When You Take It Out?

Let’s play the tape forward. You are 32. You have had a Mirena for five years. You are ready to start trying for a baby. What happens next?

You walk into the clinic, the doctor pulls the strings (it takes 30 seconds), and you might feel a little cramp. And then? Your fertility comes roaring back.

A major study tracking women who had IUDs removed specifically because they wanted to get pregnant found that 83.3% conceived within two years. The average time to pregnancy? Just over 8 months . For younger women under 35, that timeline shrinks even more.

Your uterine lining, which thinned slightly on the hormonal IUD, plumps right back up. Your cycle regulates. The copper IUD, which has no hormones, leaves your system the second it is removed. Unlike the Depo shot, which can take months to wear off, IUDs offer an instant return to fertility.

The Comparison: Hormonal IUD vs. Copper IUD

If you are shopping for birth control right now, you are likely staring at two choices. Let’s look at how they play into the fertility picture, because they are very different beasts.

Hormonal IUD (Mirena, Kyleena, Liletta)

• How it works: Thickens cervical mucus to block sperm; sometimes stops ovulation.

• The Fertility Vibe: Totally reversible. Often preferred by women who have heavy, painful periods. It calms the uterus down.

• The Wait time to get pregnant: Instant. You can ovulate in your first cycle after removal.

• The “Off” switch: After removal, periods usually get heavier again (which is a good sign for building uterine lining).

Copper IUD (Paragard)

• How it works: Creates a toxic environment for sperm using copper ions (no hormones).

• The Fertility Vibe: Totally reversible. The go to for women who hate hormones.

• The Wait time to get pregnant: Instant. Ovulation was happening the whole time you had it in.

• The Catch: It can make periods heavier and crampier. If you already have painful periods, this might be rough.

The Verdict: Neither damages your eggs. Neither scars your tubes. Neither causes “depleted ovarian reserve.” You are not “using up” your eggs by being on an IUD.

But What About Egg Freezing? 

Here is where it gets really interesting, and a little mind blowing. We live in an era where many women are freezing their eggs to buy time. Usually, doctors say “take your IUD out” before a retrieval cycle, because a hormonal IUD thins the lining. However, new research presented at the ASRM Scientific Congress looked at 5,428 egg donors.

The result? Women who kept their IUDs in during the egg retrieval process had comparable results to those without IUDs . The IUD did not reduce the number of eggs retrieved or hurt the quality.

Why does this matter? Because it proves that IUDs are passive. They sit there, they do their local job, but they don’t send systemic shockwaves through your ovaries. Your eggs are safe in their little follicles, IUD or not.

What SHOULD You Worry About?

Look, no method is 100% risk free. While the infertility risk is a myth, there are real things to watch for.

The only real risk factor for future pregnancy related to IUDs is infection.

• If you get Pelvic Inflammatory Disease (PID) while the IUD is in place, that can cause scarring.

• However, the actual risk of PID in IUD users is super low. According to the WHO, the average incidence is only about 1.6 events per 1,000 person-years.

• That risk is highest in the first 20 days after insertion.

So, here is your action plan if you are worried:

1. Get tested before insertion. Make sure you don’t have chlamydia or gonorrhea hanging out unnoticed.

2. Watch for red flags. If after insertion you get a fever, weird discharge, or horrible pelvic pain, call your doctor immediately. That isn’t “normal” cramps. That could be an infection that needs antibiotics.

Ready to take the next step? If you are considering an IUD but have a history of heavy periods or cramps, ask your provider specifically about the hormonal IUD. Many women find that it actually improves their uterine health by reducing bleeding, which can be a huge plus when you eventually try to conceive.

When You’re Ready to Try

If you are reading this because you have an IUD right now and you want to get pregnant, here is the game plan.

Step one: Schedule the removal appointment. Do not try to do it yourself.
Step two: Start taking prenatal vitamins before you try to conceive.
Step three: Relax. Give your body three months. For 80% of women, that is all it takes.

If it takes longer than a year (or six months if you are over 35), do not blame the IUD. The IUD didn’t break anything. At that point, you are dealing with the normal statistics of fertility: age, genetics, or other factors like PCOS or male factor infertility.

If you are still nervous, make a “fertility checkup” appointment

Stop letting the ghost of birth control past scare you away from one of the most effective forms of contraception on the market.

The IUD is a tool. It pauses pregnancy. It does not destroy the factory.

If you are still nervous, make a “fertility checkup” appointment. It doesn’t commit you to getting the IUD. Just ask for an ultrasound and a basic hormone panel. Knowing your AMH levels and your ovarian reserve gives you a snapshot of your current fertility. Compare that number to the research. You will see that the IUD isn’t the threat you thought it was.

Your future family is not at risk. Your peace of mind, however, shouldn’t be either. Go get the birth control that works for your life right now. Your body knows how to bounce back when you are ready. Trust it.
