4 Unexpected Reasons Why Condoms Cause UTI

Do condoms cause urinary tract infections (UTIs)? If so, why? Let’s take a look at several clinical research papers to better understand the link between condom use and UTIs.

Quick Summary

First of all, sex increases your risk of developing a UTI.  Period. Regardless whether you use condoms or not.

However, if you are using condoms with spermicide you are increasing the risk significantly. Let’s see why.

#1 Healthy Vagina Protects From UTIs

UTI happens in a bladder, so why condoms cause UTI? And why vaginal flora is important?

It appears that more than 90% of all UTIs worldwide caused by E. coli bacteria that live in your gut and sometimes ascend to your vagina.

Frankly, it doesn’t take much for bacteria to make their way from your anus area toward your vagina, even with perfect hygiene.

Thankfully, healthy vaginal flora is not suitable for E. coli. Basically, if vaginal flora is balanced, the invaders will be “kicked out”. On a contrary, if vaginal flora is compromised, harmful bacteria will thrive.

As you can imagine, during sex some of the vaginal fluids would be spread toward the urethra (unfortunately, the urethra is right next to clitoris). Therefore, if your “vaginal juices” are full of harmful bacteria, the chances to contract a UTI skyrocket.

Therefore, healthy vagina works as a natural defense mechanism against recurrent UTIs. And now we are getting closer to solve the mystery of how condoms cause UTI.

#2 It’s The Spermicide, Stupid

First of all, good news: not all condoms increase your chances to contract a UTI. Look for condoms without spermicide.

A group of scientists conducted an experiment and concluded that spermicide-coated condoms were responsible for 42% of UTI cases.

If a woman used a condom with spermicide five times within two weeks, her risk of contracting a UTI was five times higher (!) than a woman using other forms of contraception.

Therefore, this is spermicide that you should avoid, not condoms. What’s so bad about spermicide-coated condoms?

#3 Spermicide Helps E. coli

Unfortunately, spermicide on the condoms facilitates the growth of E. coli. and enhances it’s adherence to epithelial cells in the vagina. And as we discussed earlier, you do not want E. coli growing in your vagina.

This means that E. coli bacteria that made their way to your vagina will be able to thrive an multiply and wait for the next opportunity to get closer to your urethra.

If you are using spermicide-coated condoms, you are basically helping your own enemy.

#4 Nonoxynol-9 Is Bad For Good Bacteria

But wait, there is more!

The spermicide (Nonoxynol-9) suppresses the growth of healthy vaginal flora (lactobacilli), the beneficial bacteria that live in your vagina. Compromised vaginal flora means that E. coli have better living conditions, and that leads to increased risk of UTIs.

Moreover, increased use of products with Nonoxynol-9 is associated with increased risk of bacterial vaginosis, epithelial disruption, and inflammation of the genital mucosa.

If you have to use spermicide-coated condoms, make sure to restore your “good bacteria” with special probiotics, such as RepHresh Pro-B Probiotic Feminine Supplement, 30-Count Capsules.

Do condoms cause UTIs? Remeber this:

  • Avoid using products with Nonoxynol-9
    • Nonoxynol-9 helps bad bacteria to grow
    • Nonoxynol-9 hurts your good bacteria

Things To Consider If You Think That Condoms Cause UTI

The truth is, if you keep getting UTIs, condoms are not always the reason or not the only reason:

Unfortunately, recurrent UTIs could be an indicator of various health issues. Check out these possible health-related risk factors for UTI:




  1. My husband and I started using coconut oil as a lubricant and it has drastically reduced the chance of me getting a UTI. Of course I still have to immediately empty my bladder and wash myself afterwards, but the coconut oil has been a huge game changer.

  2. I have dealt with UTIs my whole life thanks to my peculiar anatomy. They have lead to serious bladder and kidney infections. It took multiple doctors and ultimately becoming my own advocate to finally figure it out. I’ve been UTI free for 2 years!!!! That is, until my current partner and I became active and he preferred Trojan brand condoms….. I don’t have an issue with Durex at all, but there is something in the Trojan brand that just does not sit well with my body. Learn and get comfortable with your body, fight for proper care and most of all, listen to your body!

  3. We used to use a lubricant from Durex which was with a dispenser for years and never had issues. Since we switched to a different one which is in a tube that you have to touch with your fingers, I had three UTIs. We’re going back to the other lubricant which won’t be contaminated through fingers.

    • Hello!
      Great point. However, all cosmetic and OTC products available in USA, especially from big brand like Durex, go through microbiological testing, which means that common bacteria are intentionally introduced into the product to see if preservative kills it. In general, contamination with fingers is something every company forecasts would happen, and therefore they add some serious preservatives to make sure bacteria won’t grow. I’d be very interested to hear again from you and your experience with new packaging.

  4. I am glad I found this article! I knew it wasnt me and it was in fact the condoms! I have been suffering by UTIS since I lost my virginity a few years ago! Every year I would spend so much money on doctors that only subcribe me antibiotics and never once told me it could be the condoms!

    • Hi Carolina,
      I’m glad it brought some clarity, I want to highlight though that underlying reason is misbalances vaginal flora, and condoms with spermicide or lube play their own role in aggravating the problem. Try condoms without lube and spermicide and use water based lube, see how this goes. BUT in the meantime make sure to restore your vaginal flora with particular type of probiotics and if you had multiple infections, check out other supplements to help you heal your bladder.

  5. Awesome that you suggest taking probiotics and cranberry pills. I have suffered from chronic UTI’S for 2 yrs now and my doctor and specialist seem to be no help as they keep prescribing more and more antibiotics. I just want to stop them in the first place!! I do not use condoms as I’ve read they can be a contributing factor. I am peeing before and after and drinking lots of water. Could my partner be a factor as well?Any other vitamins or anything I can do that you recommend? Thanks.

  6. This makes a lot of sense! Thanks for the article. I wanted to share that for almost two years I’ve been getting frequent UTIs and didn’t know why until I started thinking about what condoms I had been using. I found that along with taking a probiotic, taking Horsetail daily, and D-Mannose after intercourse, prevented most of my UTIs.

    • Hi Rebekah
      just wondering do you only take a D-Mannose after intercourse? cause i suffer from the same thing but when using no condoms i get it


    • Hi Rispa,
      Sorry to hear! A condom itself is not a reason for a urinary tract infection, but using condoms with spermicide is linked to an increased risk of contracting a UTI because the spermicide negatively affects vaginal flora. UTI is better than an STD anyways 🙂 just choose condoms without spermicide and see if this works better for you!

  7. Wow!

    I’m so happy I found this blog and its current and not dated several years ago ! I’m a 57 year old Lady and in the past few months, nearly every other month I get an UTI after sex. My husband and I’ve been married 16 years, and even with a condom I get UTIs at times. Am I to understand correctly that Condoms WITH a lubricant on them are bad ? Also, I’ve began taking Cranberry Supplements. 500 mg. Twice per day. -Thanks-

    • Haha 🙂 Lisa, I’m happy you found us!
      First of all, sorry for your troubles, this must be worrisome. Here are couple posts for you to get you started on prevention:
      1) Importance of probiotics to prevent UTIs. Also explains what type of probiotics are recommended
      2) D-mannose supplementation explained in details here and here
      3) Also make sure to check this one estrogen and UTI
      To answer your question:
      I personally believe that yes, condoms coated with a lubricant (especially with spermicide) could be provoking your UTIs.
      Contrary to the popular believe cranberry supplements haven’t been proven to be helpful 🙂
      Let me know what you end up taking and please share your experience as time goes by! Best wishes

  8. I’m so glad I ran into this article. I’m 54 yrs old.. Two weeks ago my husband and I were intimate and I suggest he use a condom.. Two days later I had cramps and my stomach hurt a lot.. Went to the doctor thinking that I had a UTI due to pain after I went to the bathroom.. So they did a urine test and ended up I had E. coli in my intestines.. Can a old condom give me this E. coli? Remember again these systems happened after we had sex.. Need answers.,

    • Hi Margie,
      Sorry for the late reply – I was away for two weeks.
      A condom itself won’t give you E. Coli. It is actually a bacteria that is constantly present in your guts, it only causes trouble when it is misplaced – introduced into your urethra during (for example) sex. Condoms could be an aggravating factor since they can mess with your vaginal flora.

      Hope this helps and you are feeling better!
      Please let me know if you received any treatment from your physician and how you are feeling.

  9. I’m so glad this web page is up. Seriously the information above is my situation. But its me who wants to use the Condoms. I have been dating him for 5 months n have got two of them since then. I’m having one now ugh. I’m 45 yrs. Old n never had so many In this short of time. I thought it might be the mothers apple cider vinger I have started to use n now I know what is causing this. Ty sooooooo much for the information.

    • Hi Michelle,
      I’m glad to hear that this is helpful!
      How are you treating the UTIs? If with antibiotics, make sure to strengthen your vaginal flora with probiotics once finished with the treatment and go hardcore on prevention!
      Hope this would be the last one,

  10. Hi!
    Thank you SO much.
    I started dating my boyfriend 4 months ago and I have had two UTIs since then and two yeast infections from the antibiotics.
    Currently on my second one and it sucks so bad!!
    My boyfriend insists on spermicide condoms and i just know thought that they could be the issue.
    I’m so happy i found an answer and am looking forward to not getting another UTI!!!
    Thank you

    • Dear Melissa,

      Sorry to hear! Hang in there and talk to your guy about the options. UTIs are bad, but unwanted pregnancies are worse! Glad that he is considerate and takes it seriously. Perhaps if you drink a course of probiotics you’ll be able to snap yourself out of the vicious cycle. Definitely try as many preventive measures as you could: good hygiene, drink some d-mannose water to be on a safe side. Hopefully this is your last one!
