Your Guide to Non-Hormonal Birth Control Part 1: The Copper IUD


In last week’s blog post, I talked about the downside of hormonal birth control, specifically the pill. While the pill provides awesome sexual freedom, it does not come without its consequences and side effects. Finding a good form of non-hormonal birth control can be challenging. And sometimes it feel like there are tons of options out there. One form of non-hormonal contraception that has been gaining a lot of popularity these days is the copper IUD.


What is the Copper IUD?


The Copper IUD is an intrauterine device that is inserted by a doctor into the uterus. A copper wire is wound around the stem of the t-shaped device. The device can stay in place for up to 10 years and has an effectiveness of 99.8%.


How Does the Copper IUD work?


The copper that is woven into the device interferes with sperm movement and prevents the sperm from fertilizing copper IUDthe egg. The IUD increases the amount of copper ions, prostaglandins and white blood cells in the uterus which interferes with fertilization. If fertilization cannot happen then pregnancy cannot happen.


The copper also affects the transport of the egg out of the Fallopian tube and the copper that leaches out of the IUD makes the uterus less suitable for implantation and pregnancy.


The IUD does not protect against sexually transmitted infections.


What are the Contraindications?


The following are a list of contraindications for the use of any IUD:

  • Uterus distortion
  • Active pelvic infection
  • Known or suspected pregnancy
  • Wilson’s disease or copper allergy
  • Undiagnosed abnormal uterine bleeding
  • Current or previous breast cancer
  • Dysmenorrhea or menorrhagia (for copper IUD only)
  • Have a bleeding disorder or take blood thinners
  • Have had a STD



The Positives of the Copper IUD


  • Once inserted nothing needs to be done except a monthly self-check to make sure that the strings are in place and that the device has not shifted.
  • It is 99.8% effective against pregnancy. Less than 1 in 100 women a year get pregnant using the copper IUD.
  • You can take it out whenever you want by just visiting your doctor.


The Negatives of the Copper IUD


  • Ovarian Cysts. There is some evidence that suggest the copper IUD may increase your risk of developing ovarian cysts.
  • Heavier & More Painful Period The increase in prostaglandins (which are pro-inflammatory) can dramatically increase inflammation during menstruation. This means that a women may experience increased menstrual cramping and heavier bleeding during her period. This is one of the main reasons women decide to remove their IUD. It can cause a lot of discomfort. But for many women this subsides after 3-6 months with the IUD.
  • In some cases the copper IUD can spontaneously expel itself from the uterus. Expulsion rates vary from 2.2 – 11.4 % depending on how long she has had the device in her body.


  • Irregular bleeding can occur as well as spotting between periods. This occurs more frequently during the first 3-6 months and less frequently thereafter.


  • Pelvic Inflammatory Disease. This is a bacterial infection that may lead to infertility, chronic pelvic pain and ectopic pregnancy. The good news is that the risk is small and only exists within the first 21 days of insertion. The risk is likely related to the presence of pre-existing gonorrhea and chlamydia at the time of insertion.


  • In rare cases, the IUD can move through the wall of the uterus and damage other internal organs. Sometimes surgery is needed to remove it. The risk is very low, about 1 in 1000 insertions, and is usually related to the skill of the doctor performing it.


  • Although pregnancy is rare on the copper IUD, if it does occur, the risk of ectopic pregnancy is high. This occurs when the embryo implants somewhere other than the uterus, such as the fallopian tubes. In the case of an ectopic pregnancy, the embryo has little chance of surviving.


The Copper IUD and Copper Toxicity


This is one aspect of the copper IUD that is not often discussed among the medical community. As a nutrition practitioner who has run many Hair Tissue Mineral Analysis’ on women using this form of contraception, I have seen excessively high copper levels in many women using the copper IUD.


The copper IUD may not cause copper toxicity in itself but if you are also exposed to copper from other sources then it can build up and cause an excess in your system. Other sources that can contribute to copper toxicity include: public swimming pools. copper pipes, copper cookware, inorganic mineral supplements, dental crowns, beer and a vegan/vegetarian diet that is high in copper containing foods.


If your liver is congested or struggling to deal with other toxins, it may be inefficient at removing excess copper from the body. This can lead to a buildup of copper.


While copper is needed in certain amounts it can cause negative symptoms if it builds up.



Symptoms of Copper Toxicity Include:


  • Feelings of doom
  • Fatigue and exhaustion
  • Headaches
  • Moodiness
  • Cold hands and/or feet
  • Bone and joint disturbance
  • Anemia
  • Neurologic impairment


Another way that too much copper can affect the body has to do with zinc. Zinc and copper compete for absorption in the body. Too much zinc can drive copper down and too much copper can cause zinc deficiency. Zinc is a crucial nutrient needed for immune system function, cell division, cell growth and the healing of wounds. Zinc deficiency can cause weak immunity, diarrhea, acne, leaky gut and thinning hair. Excess copper can also lower iron levels, increase vitamin A levels, aggregate B vitamin metabolism and increase estrogen levels. High estrogen levels can also cause the body to retain copper.


How to Prevent Copper Excess


  • Improve Liver Clearance. Give your liver some love so that it can better deal with excess copper in the body. Eat liver friendly foods like asparagus, watercress, turmeric, grapefruit and dandelion. You may also want to take a liver support supplement like milk thistle.


  • Increase your Consumption of Zinc. Foods that are high in zinc include grass-fed beef, pumpkin seeds, shellfish, lamb and cashews. You might also want to consider a high quality zinc supplement, especially when digestion is an issue. Choose a chelated form for best absorption like zinc gluconate.


  • Reduce your Exposure to environmental copper like copper pipes, cookware, swimming pools and high copper foods.


  • Reconsider your Vegan Diet. Meat products are full of zinc and little copper and plant foods, especially soy, beans and legumes, are full of copper and little zinc. While using the copper IUD it may be a good idea to include more animal products in your diet and cut down on high copper containing foods.


  • Get your Mineral Levels Checked. After 3-6 months on the copper IUD, I recommend running a Hair Tissue Mineral Analysis to detect early build-up of copper.


  • Get your Hormones Checked. If your estrogen is too high, then there is a high possibility that your body is retaining copper rather than eliminating it. You may also want to see if the copper is driving up your estrogen and causing estrogen dominance.


  • Improve Stress Levels. Chronic stress uses up the body’s zinc stores quickly. By improving your stress levels you can increase your zinc and reduce copper toxicity issues.


Final Thoughts


While the risks are small with the copper IUD, these are still risks that need to be considered. The chances are you will have a relatively good experience with this form of contraception. But the bottom line is that any small changes to your delicate hormone balance can cause symptoms.


The important thing is to be aware of any new symptoms that pop up. While many doctors will tell you there are no emotional symptoms involved (since the copper IUD does not emit hormones), this is not true. There are many stories of women who experience feelings of doom, depression and moodiness while using the copper IUD.


If you do decide to use the copper IUD, take steps to improve your nutrition, prevent copper toxicity and improve your zinc status.


And more importantly, make an informed decision and decide whether the risks are worth the benefits. And if you have any experiences using the copper IUD, please feel free to share them below!

Are you going to be writing about other non-hormonal options? Have been meaning to do some research on this. In your personal opinion is the copper IUD the best non-hormonal option?

    Kendra Perry - August 21, 2015

    Hey Hannah,

    I just posted an article about the Fertility Awareness Method which is my personal favorite. I can’t really say if I think the copper IUD is the best hormonal option. I do think it’s a great option for some women. But everyone is so different so it might be a terrible option for others. I think if choosing this option, it’s good to take steps to reduce possible side effects and get your minerals checked after three months of use to detect any potential copper toxicity.

Thanks for your article and acknowledging that the copper IUD can and does cause side effects like anxiety, weight gain, etc… which are normally only attributed to hormonal IUDs and which many doctors say “cannot” be caused by the copper, since it doesn’t actually contain hormones.

As someone who has personally suffered very devastating effects from a copper IUD, I am trying to come to understand how this happens. One thing I have read is that the prostaglandins which are produced in response to the copper (which are part of how it prevents pregnancy) can also stimulate the production of hormones such as estrogen and progesterone. If this is true then it would make sense that a copper IUD would then have the potential to cause side effects normally attributed only to hormonal IUDs. Have you ever heard this or do you have any explanations on how the copper could affect hormone balance.?


PS There are several very active support groups on Facebook which are growing rapidly with women suffering from all kinds of side effects from IUDs. Many many of them have been repeatedly told by their doctors that their problems “cannot” be because of their IUDs. I personally know mine were as they started going away just 2 days after removal!
Most of the support groups are for the Mirena hormonal IUD as it is much more prevalent than the Paragard copper IUD, however there is a group which is for all kinds called IUD Side Effects: Paragard, Mirena, Skyla & Liletta.

    Hey Tamara,

    Thank you so much for your comment. That totally sucks that you have struggled so much with the copper IUD. I have heard many strange stories about the copper IUD from friends. You are correct about the prostaglandins. I believe this is why the copper IUD causes increased menstrual cramping. Other effects may be due to the copport toxicity. Copper toxicity itself can cause a lot of negative side effects. Additional any toxicity can cause chronic stress on the body. Chronic stress is known to deplete hormone sex hormone production which can cause a lot of symptoms itself.

    I hate that doctors make women feel crazy when they are experiencing symptoms from this. Just because it doesn’t directly influence your hormones, doesn’t mean it can’t have side effects. In the end it is a foreign object in your body and not everyone is going to respond well to this.

    Thank you so much for sharing this support group. I think many women will benefit from this. Thank you!

I was on the Depo Provera shot once and the whole time I was depressed and had extreme anxiety so I got the IUD And it’s been 6 months and I feel faint and I still have racing thoughts and very panicky and it gets worse when I get my period I’ve never experienced anything like this in my life it’s the worst thing ever … I’m thinking about removing the copper IUD but my doctors swear it isn’t the IUD

    Kendra Perry - May 8, 2018

    It is absolutely the IUD. Copper has profound metabolic consequences. Check out this website for more information:

Terri - May 5, 2018

Hi! I just want to clarify. I had the copper iud placed in 2016 and it was enough to cause a complete personality shift/paranoia/anxiety/ect. It will depend on if you have an adrenal condidtion that is similar to Wilson’s disease (which most are not aware they have). I’m completely fine and calm now a year after detoxing. Check out to read other women’s similar testimonials. In my case there were not other factors like vegetarianism or copper piping in my home. Every body is different and you are in fact putting a very reactive metal directly into your body.

    Kendra Perry - May 8, 2018

    Thanks for sharing, Terri! I am totally onboard with this. My understanding of copper in the body has shifted substantially since writing this article. I am a huge fan of and would recommend all women using hormonal birth control take a look. I have witnessed many women have the same situation as you after using the copper IUD. Thanks so much for sharing!

Hi Kendra! Thank you for writing this! I have done a lot of reading for 6 weeks and had my Paragard taken out this week. I am very active and a clean eater–I have gained 30lbs in the last year and a half, along with having brain fog, and horrible migraines. I have never had a migraine in my life! Do you recommend the zinc supplements with continued exercise and clean eating to help shed the excess weight after removal?? If not, what do you recommend? I have also visited

    Kendra Perry - July 25, 2018

    Hey Courtney!

    Thanks for reading. Copper toxicity can definitely cause a lot of the symptoms you are experiencing. I wouldn’t recommend any minerals though without a full mineral panel. Zinc can lower sodium and taking it often makes people feel worse. Especially those who already have low sodium. I would recommend doing things to increase bile as that can help with copper detox. Bitters, oxbile, coffee enemas are all great ways to support this. If you are up for it, I recommend doing mineral testing with me. Copper detox can take years (and even longer if you don’t know what you are doing) but with the proper mineral support it can be much quicker and more enjoyable 🙂

      Courtney DeForest - July 25, 2018

      I booked a call with you for next Thursday. 🙂 Let me know if something opens up sooner!

        Kendra Perry - July 25, 2018

        That’s great! Looking forward to it. Things have been BUSY AF lately so it’s unlikely that something will open up sooner but I will let you know if it does 🙂
