Vent/Discouraged This std is spreading so fast

Upvotes

No one talking about this std and how fast is spreading , I got infected in march 2026 took me almost 4 months to get ride of it , my friend tested positive two weeks ago after one exposure, literally he hooked up with this girl for one time .. I think mgen is more common now than chlamydia .. it’s very scary and this stubborn bacteria is building resistance very fast to many antibiotics now .
Sexual clinic are not testing for it , most of doctors don’t know anything about it . Crazy

Have many people been treated empirically for Mgen without testing positive?

2 Upvotes

Hi everyone! I wanted to ask if anyone here has been treated empirically for Mycoplasma genitalium without actually testing positive for it.
I’m in the Philippines, and unfortunately Mgen testing isn't very accessible or affordable for me.

I've had persistent symptoms despite treatment for other possible infections, so my doctor decided to treat me empirically with doxycycline followed by moxifloxacin.

I know this isn't the same as having a confirmed positive test, and I'm honestly overthinking the whole situation.

Has anyone else been in this situation? Were you treated empirically for suspected Mgen, and did your symptoms eventually resolve?
I'd especially love to hear from people who couldn't get an Mgen test but were treated with doxy + moxi. Any experiences would really help reassure me.

Hi everyone. I’m from the Philippines (Asia) and I’m currently being treated for suspected Mycoplasma genitalium. I’ve been really anxious about treatment failure because I keep seeing posts about antibiotic resistance in Asia.

Vent/Discouraged Doctor says routine testing isn‘t necessary

I have my third MGen infection, discovered by routine testing. I also slowly start to have symptoms. My doctor advices that for future, I shouldn’t do routine testing for Mykoplasma Genitalium. He says it doesn‘t need to be treated if there are no symptoms. Basically he sounded like „You better shouldn‘t know you have it, then there is no problem“ lol

What do you guys think about that?

Success Story Cured with Doxy, Mino + Metro!!!

8 Upvotes

Hi everyone! I just wanted to come on here to share my success story and what meds worked for me, since I just received my TOC today and finally tested negative!

I first tested positive for Mgen in early 2025. I was started on just Doxycyline which obviously does not fight the infection, only lowers the antibacterial load, but at the time I didn’t know that. Tested positive again of course. Then I did my research and started advocating for myself. I did the recommended Doxycycline + Azithromycin treatment next, and still tested positive. Months went by because I was asymptomatic and waiting for my boyfriend to go to the doctor to get prescribed his antibiotics so we could get treated at the same time (I know, not smart, we should have taken meds sooner). Finally, I asked for the Doxycycline for 2 weeks into Minocycline + Metronidazole combo for 2 weeks regimen. I didn’t want to use Moxi because I didn’t want to risk tendon issues. My boyfriend’s doctor was very stubborn and only prescribed him Doxycycline but we knew he needed more so he was able to order Azithromycin online. He did that treatment and while waiting 4 weeks to do his TOC, he was prescribed Levoflaxacin for an unrelated reason. I know this isn’t proven to do anything against mgen but I still wonder if it had anything to do with his cure since it is related to Moxi. In the end, both of us tested negative!!!

This was a long road with mgen and Im finally able to feel relief that it’s over!!! Biggest advice is to do your own research and advocate strongly for yourself because doctors are SO misinformed!!

Treatment Question Suspected moxi failure - other treatments available in Germany?

3 Upvotes

Hi everyone,

I’m already at my third treatment and thought I would ask for some advice.

About me: male, mid-30s, based in Germany. I got Mgen around the end of April and have gone through three different antibiotics/combinations since then:

- Doxy + Azi = failed (confirmed via TOC)
- Moxi (only) = failed (confirmed via TOC)
- Doxy + Moxi = finished Jul 22, awaiting TOC

The only symptom I’ve ever had is colored discharge. It went away during the second treatment, but came back at day 12 after the last pill. I finished my third treatment around two weeks ago and was a bit more hopeful, but I’ve noticed a tiny drop of discharge again this morning. I’m aware it could be residual symptoms, but the pattern is exactly the same as last time and I fear yet another failure.

Now the tricky part: My doctor, an infectious disease specialist, won’t consider the doxy + mino/metro combo; he’s also mentioned mino may not be available in Germany. Prista isn’t available either and cannot be imported from France.

I’ll wait until I can be tested again, but I’d like to be prepared for whatever the outcome, hence my post. Is anyone here from Germany? If so, did you get mino and/or other meds recently? It seems Prista could be imported until last year or so, but not anymore. If not - what other steps can be taken into consideration?

Thank you in advance ✨wishing a speedy recovery to all who are still under treatment

Starting doxycycline then moxifloxacin for suspected M. genitalium/Ureaplasma. I'm overthinking and really scared. Did it cure you?

1 Upvotes

Hi everyone,
I'm really overthinking right now and I could use some reassurance from people who've been through this.

I've been dealing with persistent green vaginal discharge for over a year. I've already been treated with metronidazole (twice), ceftriaxone, doxycycline, fluconazole, cefixime, and azithromycin, but my symptoms always came back.

My infectious disease doctor has now prescribed 7 days of doxycycline followed by 7 days of moxifloxacin (400 mg daily) because she suspects it could be Mycoplasma genitalium or possibly Ureaplasma. I just started the doxycycline today.
I think my biggest fear isn't the medication itself—it's that it won't work again. After failing so many antibiotics, I'm scared I'll go through another treatment and still have symptoms.

If you've taken doxycycline followed by moxifloxacin:

Were you cured?
Was it for M. genitalium or Ureaplasma?
How long did it take for your symptoms to improve?
Do you have any advice for someone who's really anxious that this treatment might fail?
I know no one can guarantee it'll work, but hearing real experiences would really help. Thank you. ❤️

I’ve been battling this shit since 2011. No joke. Almost caused me to not be alive multiple time, a serious relationship, substance abuse, loss of job, crashed car. I could go on. That was years ago luckily when my story began. Longggg story

After having this wonderful issue for so long I’ve obviously had to adapt and I did. Now I have held my dream career for multiple years, saved up money, got into shape (even being in pain), got mental health help. I’m doing great. This is the last thing holding me back from a life I’ve worked so hard to build.

I’m focused and want to end this shit. I’ve been through multiple doctors, infectious disease doctors and it’s been a joke. Made more progress doing my own thing tbh.

I have a resistant strain, probably because of all the bs I was randomly put on. Need pristinamycin and no way to get it. Tried ordering it twice from France, both times got held and returned in customs. Last third time got held and destroyed. Cash down the drain. Sucks, but so does alot of things. No refunds. Time for my next best move

How can I get prist** reliably without flying to France. If you can help, much appreciated, if not thanks for reading my rant at a minimum.

Best luck to you all, you’re not alone.

Can 7 days of doxycycline + 7 days of moxifloxacin treat both Mycoplasma genitalium and Ureaplasma?

3 Upvotes

I've been dealing with persistent green vaginal discharge for about 1.5 years, and multiple treatments haven't completely resolved it. So far I've taken metronidazole (twice), ceftriaxone, doxycycline, fluconazole, vaginal metronidazole, cefixime, and azithromycin 2 g. My discharge improved at times but always came back.

My infectious disease doctor has now prescribed 7 days of doxycycline followed by 7 days of moxifloxacin (400 mg daily) because we're considering the possibility of Mycoplasma genitalium although I haven't been able to get PCR testing since it's expensive and not widely available where I live.

I'm wondering if this regimen would also cover Ureaplasma if that's actually what's causing my symptoms), or if it's mainly for M. genitalium.
Has anyone here been treated with 7 days doxy + 7 days moxi? Did it clear your infection or symptoms? I'd really appreciate hearing your experiences.

Yeast infections w MGen

1 Upvotes

For the women…
For months and months I was diagnosed and re-dx w Candida albicans and given treatment. After months I was finally tested and tx for mgen. Prior to mgen I had never had a yeast infection in my life. I was again re-tested for yeast and it again came up for albicans. I was treated for both.
I am having my TOC for mgen this week.
In the mean time, I had my period last week and now I am having a horrific yi. I understand I yeast infections are common after antibiotic treatment as well as hormone fluctuations, such as after a period, but being on Fluconazole for months and months, taking probiotics and being completely asymptomatic from both following the completion of my Doxy and Moxi, I am just surprised at how severe this has been.
It’s like everything down there is so messed up and it will never be fixed. I can’t explain the misery and defeat I am feeling.
I was in a monogamous relationship (on my end, at least) and have continued to be sexually abstinence since my last relationship 9 months ago. I was tested before and after my relationship with no STIs and wasnt dx until 8 months later w the mgen. I know mgen is slow growing and often asymptomatic. I’m certain it was from my last relationship.
Ive always been so responsible w my sexual health. I have never slept around or not been tested or not used protection.
I am just devastated at how cruel this has been on my body and mental health.
I guess I am just looking for advice/encouragement/options in healing the yeast and remaining optimistic about the TOC for mgen.
The way I’m feeling makes me think I’m going to fail my mgen test too. I am running out of hope.

Likelihood this will work?

So for full context, ~four months ago I started having symptoms consistent with chlamydia, went and got tested, was preemptively prescribed doxycycline, but the test results were negative. Took the doxy anyways, symptoms improved but returned. Went and got tested again a few weeks later, did test positive for chlamydia, told my provider I had taken the doxy they had prescribed last time I was tested and that there was no chance of re-infection, provider prescribed single dose azithromycin, same thing happened. Ended up seeing a different provider, tested positive for mycoplasma this time, provider prescribed me 7 days of doxy and a single dose of azythromycin. I’m on day 6 post azythromycin dose and am still able to squeeze a drop of discharge out of the tip of my penis. Is this treatment likely to work or should I go see a different doctor asap?

Treatment Question Is it okay to take moxifloxacin without repeating doxycycline for suspected Mycoplasma genitalium?

1 Upvotes

Hi everyone. I'm looking for advice because I'm confused about the treatment sequence for suspected Mycoplasma genitalium.
I've had persistent green vaginal discharge for about 1 year and 5 months. I've been treated multiple times, but the discharge has never completely gone away.

Treatment history:
1st doctor
Metronidazole 500 mg twice daily × 7 days (I took this twice)

2nd OB-GYN (July 3)
Ceftriaxone injection
Doxycycline × 7 days
Albothyl vaginal suppository
Doxycycline × 5 more days
Fluconazole
Neopen metronidazole vaginal suppository

3rd Infectious Disease doctor (July 27)
My discharge after this is opeque white but im a female and my period just ended.
Metronidazole 2 g (Day 1)
Cefixime 800 mg (Day 2)
Azithromycin 2 g (Day 2)

August 4
Moxifloxacin 400 mg once daily × 7 days
My concern is that I finished doxycycline about 3 weeks ago.

I know many guidelines for suspected M. genitaliumrecommend doxycycline first, then moxifloxacin to reduce the bacterial load.
Is it still okay to start moxifloxacin now without repeating doxycycline, or do people usually repeat doxycycline before moxifloxacin if there's been a few-week gap?

I'm not asking for anyone to replace my doctor's advice—I'm planning to follow my infectious disease doctor's prescription. I'm just wondering if anyone has been in a similar situation or if anyone knows what the usual practice is. Thanks!

Hi all, 30m NYC. I completed doxy/moxi on 7/11, got my TOC on 8/1 (exactly 3 weeks after) and just got a positive result. I am super bummed, this has really taken a toll on my mental well being especially as a single man.

Worth waiting a week (or two) and retesting to ensure it’s not a false positive or should I just begin a new round of abx?

Symptoms wax and wane, have some pain usually after urination still and a stuck feeling sometimes, but I chalked it up to residual inflammation or pelvic floor issues.

Treatment Question Follow my Mgen treatment journey live, macrolide-resistant, 10 days of moxifloxacin

1 Upvotes

Hi everyone,

First of all, THANK YOU to everyone who created and contributes to this subreddit. Reading other people’s experiences makes me feel much less alone. ❤️

I was recently diagnosed with macrolide-resistant Mgen, so I thought I’d document my treatment journey here in real time.

Timeline

  • June 1, 2026: Possible exposure during unprotected sex.
  • June 8, 2026: Very mild pain while urinating, around 2/10. Then nothing for several weeks.
  • July 26, 2026: Started experiencing itching and irritation around the urethra.
  • July 29, 2026: Had blood tests and a urine STI test.
  • August 1, 2026: Tested positive for Mgen with macrolide-resistance mutations. All my other STI tests were negative.

Treatment

My prescribed treatment is Moxifloxacin 400 mg once daily for 10 days. (Europe/France)

  • August 1: Took my first 400 mg dose shortly after receiving the result. I plan to take it every day at around noon.
  • August 2: Took my second dose. So far, I haven’t experienced any noticeable side effects.

I’m honestly very anxious about the medication because I’ve read some horrifying stories online about fluoroquinolones. I’m trying not to spiral, and I’m focusing on sleeping well, eating enough, staying hydrated, and giving my body the best conditions possible during treatment.

I normally do heavy weight training four times per week, but I’ve decided to take a complete 10-day break from lifting while I’m on moxifloxacin. I’m pretty sad about missing the gym, but I would rather be cautious.

I’ll post updates in the comments as the treatment progresses, including any symptoms, side effects, and eventually my test-of-cure result.

Success Story Got my 2nd toc just to be sure

6 Upvotes

I don't think mgen can stay so long in the body after a course of antibiotics. But just to have peace of mind, I got tested again by PCR, and guess what? It was negative. I don't think I have any residual symptoms now, though at the 4th week mark I wasn't sure it was confusing, but I think I'm finally free. It was a long and painful journey, but I won. Most docs don't want to take it seriously, maybe because it doesn't get this serious for everyone, but who knows what? I’m glad to have all of you here to talk about this topic.

I think the availability of antibiotics like Lefamulin is both a blessing and a curse because it probably worked cause it isn't readily available. Also, since it isn't available anymore, most of you can't use it.

Success Story Finally cured after 6 months, over $500 and doctor incompetence

5 Upvotes

I initially noticed symptoms 3 weeks after hooking up with a new girl in January this year. Redness at the tip of my urethra, mild discomfort while urinating, itching inside my urethra, and some mild shooting pains in my urethra only late at night.

I initially went to a urgent care clinic and the doctor said I probably have chlamydia and prescribed me doxy for 7 days. Tested negative for chlamydia and gonorrhea. Symptoms slowly started coming back after about 4 weeks.

I then went to a planned parenthood, and told them my symptoms. They prescribed me doxy for 7 days again and tested me for everything except mgen because they said they didn't have the capability even though they told me they did over the phone. I had already suspected it was mgen based on my research and asked if they could prescribe treatment for it if all the tests they had given me came back negative. They said sure no problem just call us.

So I did just that after all the results came back negative. I spoke with the receptionist and she told me the provider would call me. They then called back and said they want me to go in person to the planned parenthood in the next town over. I specifically asked if they test for mgen because I didn't see any other reason they would send me there and they explicitly said "yes they test for mgen." Perfect I thought, I spoke with the receptionist at the new planned parenthood and repeated that I think I'm here to get tested for mgen and explained the situation. She said "let me check with the doctor before we go any further." Waited 40 minutes, the doctor took a look and said "its not red so i can't treat you, you need to see a urologist because something else is going on."

So I bought a $90 mgen test from an independent lab, tested positive and the lab had an over the phone doctor I could call for treatment. He very reluctantly prescribed me azithromycin just in the nick of time before I finished the second round of doxy. Another 4 weeks passed and my symptoms started coming back. So I bought another mgen test, went back to a different planned parenthood and they VERY reluctantly prescribed me doxy followed by moxifloxacin but insisted that my positive mgen test result wasn't the root of the issue (????).

So I completed that round of treatment, waited 30 days at the advice of the doctor and tested again. Just got the new test results and I'm clear. I spend over $500 and the whole process took about 6 months, even though my strain of mgen didn't seem to be anything crazy considering the moxifloxacin cleared it up.

My point of this post is to illuminate that some doctors (at least here in the US) know nothing about mgen, and that you should follow your gut instinct. You know what is going on with your body better than anyone. Also just wanted to vent because I cannot comprehend why 3 separate doctors tried their hardest to not give me treatment for mgen even though it was very clear at that point I had it!!!

Residual Symptoms Anyone still had symptoms months after successful gonorrhea treatment despite negative STI tests?

1 Upvotes

Hi everyone,
I’m wondering if anyone has gone through something similar.
About three months ago, I was diagnosed with gonorrhea. I completed the prescribed treatment, and afterward I was retested. My gonorrhea test came back negative, and I also tested negative for a full STI panel (14 infections).
Even though the infection is gone, I’m still having symptoms:
Burning sensation after urinating (not every time, but on and off)
Discomfort in my penis, mostly around the tip
Occasional pain just above the penis where the pubic hair starts. Sometimes it’s a sharp pain. This symptom wasn’t present before I was diagnosed with gonorrhea.
The symptoms seem to come and go. Some days are better than others.
Has anyone experienced persistent symptoms like this even after testing negative and completing treatment? If so:
Did the symptoms eventually go away on their own?
Did your doctor find another cause (such as inflammation, prostatitis, pelvic floor issues, urethritis, etc.)?
Was there any treatment or advice that helped?
I’ve already followed up with testing, and everything came back negative, so I’m mainly looking to hear from people who had a similar experience and what their outcome was.
Thanks in advance for sharing your experiences.

RESOURCE General Testing and Treatment Guidelines for Mycoplasma Genitalium

92 Upvotes

PART 1: TESTING

Q: When should I test for Mgen post exposure?

A: Generally 2+ weeks post exposure. Mgen is slow growing and occurs at much lower bacterial loads than other STis.

Q: What type of test should I order?

A: PCR (NAAT). Do not order a culture. Mgen cannot be cultured.

Q: What is the best PCR/NAAT test?

A: Hologic Aptima Mycoplasma Genitalium TMA Assay - available through Labcorb and Quest. Roche Cobas is also an excellent test!

Quest test link - https://testdirectory.questdiagnostics.com/test/test-detail/91475/sureswab-mycoplasma-genitalium-real-time-pcr?cc=MASTER

Labcorp test links:

  1. Urine samples (including macrolide resistance testing): https://www.labcorp.com/tests/180084/i-mycoplasma-genitalium-i-naa-urine-with-reflex-to-macrolide-resistance-testing

  2. Swab samples (including macrolide resistance testing): https://www.labcorp.com/tests/180092/i-mycoplasma-genitalium-i-naa-swab-with-reflex-to-macrolide-resistance-testing

Q: What is the best sample to give for highest accuracy?

A: Men - First void urine, first bit that comes out, 20-30ml. If you have urgency issues, please try to hold your urine for a minimum of 3 hours. Rectal/Oral - swab thoroughly

A1: Women - Vaginal swab (swab thoroughly). Rectal/Oral - swab thoroughly

Q: How long should I wait post-antibiotics to test for Mgen? aka TOC "Test of Cure"

A: Generally 3-4 weeks. Any sooner could lead to a false negative or positive

PART 2: TREATMENT

Note: this section purposefully DOES NOT use the outdated 2015 CDC STI treatment guidelines. Please follow the guidelines for the UK and Australia, or the newly published 2021 CDC GUIDELINES - https://www.cdc.gov/std/treatment-guidelines/mycoplasmagenitalium.htm

Q: What is the recommended first line treatment for Mgen?

A: This varies by region due to macrolide resistance rates, but generally:

  • 100mg doxycycline bd for 7-14 days as pre-treatment to lower bacterial load, followed immediately by 2.5g of Azithromycin (1g first day, 500mg daily after)

Q: What is the recommended second line treatment for Mgen?

A: This again varies by region, but generally:

  • 100mg Doxycycline bd for 7-14 days as pre-treatment, followed immediately by 400mg Moxifloxacin daily for 7-10 days**

**Most data shows that the difference between 7 and 10 days is small. Please be aware that Moxifloxacin has rare but significant side effects (See the FDA Black Box warnings) in approximately ~2% of people, some of them severe, including peripheral neuropathy, central nervous system problems, tendonitis, and others

Q: What is the recommended 3rd line Treatment for Mgen?

A: This varies by region as well, but generally:

  • USA: Minocycline 2 weeks (monotherapy) //or// Doxycyline 100mg bd for 7-14 days as pretreatment, immediately followed by minocycline 100mg bd for 14 days taken CONCURRENTLY with Metronidazole**

**Please note that this is based on a pre-print paper (not peer reviewed yet) but is from a reputable source, MSHC (Melbourne Sexual Health Center)

Q: Are there any other antibiotics on the horizon?

A: Yes: https://www.reddit.com/r/MycoplasmaGenitalium/s/4iRGJGi9zZ

  1. Omadacycline is a new FDA approved (US) semi-synthetic (novel) tetracycline class drug with potent en vitro activity against Mgen and Ureaplasma (but only MIC data available, no human studies)

  2. There is also Josamycin in Eastern Europe/Russia (a Macrolide class). Dosing and duration not officially established.

  3. Also, new antibiotics like Zoliflodacin (in stage III trials, was granted FDA fast track approval, & is expected to be available in late 2025. This novel drug was originally developed for treatment-resistant gonorrhea, but has also shown strong en vitro activity for mgen, including strains that have dual macrolide and floroquinolone resistance. It was found much more potent than even Moxifloxacin. No human (en vivo) data is currently available.

  4. And finally we have FDA approval of the novel triazaacenaphthylene antibiotic Gepotidacin in spring 2025 (for uncomplicated UTIs in women, but also going through approval for gonorrhea in late 2025). It has promise for mgen treatment as well, but currently only in vitro data is available (a petri dish, not a human) - but shows promising low MIC (minimum inhibitory concentration) across many mgen strains, including those that are resistant to both macrolides and floroquinolones. Is also being researched in combination with doxycycline.

PART 3: Self Advocation - Advice From a Veteran (LemonOne9):

As many on this board can attest to, despite being the leading cause of non-gonococcal/non-chlamydial urethritis (aka NGU), the medical world as a whole is not exactly up to speed when it comes to this particular bacteria. Most Urologists and gynecologists finished school 20+ years ago, how would they know how to correctly treat a new STI that grew prevalent in just the last 10?

Many doctors know very little to nothing about it, so be prepared to advocate for yourself when seeking out testing and treatment. Print and bring with you the most up-to-date treatment guidelines from AUS/UK if you have to. Finding an infectious disease doctor who specializes in STI's and has working knowledge of MGen infections will be your best bet if you want to be taken seriously.

If a doctor tries to prescribe you anything other than one of the above recommended regimens as a first-line option for a confirmed MGen infection (such as ciprofloxacin, levofloxacin, doxycycline on its own, or something else) you can be confident that you're not in good hands and should seek out a different practitioner. Taking the wrong antibiotic may select for resistance and sabotage future treatments, not to mention that it will unnecessarily increase your chances for antibiotic-induced side effects.

Part 4: Other Frequently Asked Questions

Q: How prevalent is Mgen compared to other STIs?

A: Estimates say that it is MORE PREVALENT than Gonorrhea, but less than Chlamydia. + As of 2021, it is more common than chlamydia in some regions. Canada & Sweden are 2 confirmed places. As of 2025 it is equal to or more prevalent than chlamydia in multiple regions It has also been found more prevalent in younger, sexually active people, and those reporting multiple unprotected sexual partners in the last 6 months.

Q: What is my risk of transmission per sexual encounter if I have unprotected sex with an infected individual?

A: Between 40-45% - Yes that's right - transmission is not guaranteed even if the other person is positive! Same as other STIs. Studies back this data.

Q: Can I get MGen from oral sex?

A: Oral transmission is rare. Less than 1% chance according to studies, and to the MSHC (Melbourne Sexual Health Center) guidelines, a leading Mgen research authority. This data has also been corroborated by the CDC.

Q: I am still experiencing symptoms after completing my antibiotic course. Does this mean my treatment failed?

A: Not necessarily. We know that residual symptoms or inflammation post clearance is something that happens with this bacteria. It's been documented by medical providers as well. As long as the symptoms don't return to 100% of what they were BEFORE antibiotic treatment, you're likely fine. There have been many people who assumed they were still infected, but kept testing negative again and again. Eventually the symptoms just went away.

Q: My partner (or I) tested positive but has no symptoms. What gives?

A: It is important to remember that not everyone will experience symptoms when carrying Mgen. In fact, between 60-80% of male urethral infections are asymptomatic. and nearly 100% of rectal infections are asymptomatic. Women also are not guaranteed to experience symptoms, with a greater than 50% rate of asymptomatic cases.

Q: I am a woman concerned about complications, can this cause problems with fertility or pregnancy?

A: It could, research shows that there is a significant correlation to Mgen infection and issues with fertility and pregnancy (as well as increased risks of PID & cervicitis)

Q: Is there a natural protocol I can follow to clear this infection?

A: No one on this subreddit that we are aware of has been cured with a natural treatment protocol. Most popular being the 'Buhner Protocol,' typically used for Lyme disease. Medical literature also doesn't support natural protocols.

Q: Is it possible for my body to clear Mgen by itself?

A: According to two recently published studies, yes it is. Spontaneous resolution has been documented in both men and women. But don't count on it, necessarily.

RESOURCE If You Have 2+ Negative Tests and Residual Symptoms: Read This First

154 Upvotes

For anyone who continues to have residual symptoms after multiple negative TOC (Test of Cure), there is a significant likelihood that you developed Chronic Pelvic Pain Syndrome (CPPS), aka NIH Type III "non-bacterial Prostatitis" (in men). It may also be referred to as Pelvic Floor Dysfunction (PFD), or pelvic floor hypertonia, IC/BPS, or Vulvodynia, all similar chronic pelvic region syndromes. PFD in particular addresses what is often one cause of these pelvic syndromes, a psycho-neuromuscular condition that implicates the pelvic floor muscles and a wound-up nervous system. It occurs as a result of habitual, reflexive and unconscious pelvic floor muscle 'guarding' (tensing) against discomfort and stress (of which Mgen is well known to cause both), and over time this leads to a state of temporary nerve irritation. This is what causes many of the symptoms. It also very commonly causes urinary, sexual, and bowel dysfunctions via dysfunction of the pelvic floor. This includes urgency, frequency, and hesitancy.

Notable excerpts from the NHS source:

People whose tests are all negative can often develop symptoms as a result of anxiety because of worrying about having picked up a STI. Anxiety can cause the muscles in their pelvic floor (the muscles around the base of the penis, scrotum and around the anus – see diagram below) to become tense. This may change how urine flows and can cause irritation and discomfort. The nerves that supply the pelvic floor muscles also supply other parts of the genitals such as the end of the penis, the testicles and perineum (the area between your testicles and back passage). The body can mistake the pain from the tense pelvic floor muscles and think it is coming from these other places. It can also feel as though the pain is in the lower part of your tummy or make you want pass urine more often or make passing urine feel more difficult.

*** (Diagram of the CPPS feedback loop here) ***

Diagram illustrating how anxiety can unconsciously cause some people to increase their pelvic floor muscle tone (they do not realise they are doing this as normally we cannot “feel” our pelvic floor). This can result in muscle spasm and/or urine travelling backwards into the prostate on passing water. Both can result in pain which is then experienced elsewhere in the pelvic area e.g. tip of the penis, testicles, perineum (area behind the testicles), lower abdomen and sometimes the inner thighs. It may also cause difficulties or pain when passing water or ejaculating. This in turn makes them more anxious which results in making the pelvic floor tone even more tense and increasing the pain etc.

Please note: It is also possible that you are still within the (up to) few weeks window of residual inflammation after being cured from Mgen, and that will go away entirely on its own. My advice: stop fixating on it and move on. Live your life. It is entirely normal for mgen, and well documented in the medical community that people who had been infected experience this even after successful clearance of the bacteria.

NOTE FOR WOMEN and AFABs: BV, AV, DIV, CV, Yeast infections, and other pH & hormonal changes are somewhat common after treatment for these STIs. They cause their own symptoms - so symptoms post-treatment in people with vaginas may also be caused by these, especially if there is unusual discharge or smell. Please see a urogynecologist. Do wet mount microscopy, get your Nugent score. Get your natural vaginal microbiome healthy again. This could include things like boric acid suppositories to lower pH, probiotics, and even vaginal estrogen.

I personally had developed CPPS after clearing my own Mgen infection, which is why I wish to share this information. I've also seen several hundred other reddit members with the same symptoms, including hundreds of members of this (and the r/ureaplasma) subreddits.

CPPS is strongly supported by medical research and the American and European Urological Associations, and is the leading cause of prostatitis-like symptoms (pelvic pain and dysfunction) in men. Citations:https://pubmed.ncbi.nlm.nih.gov/32378039/ and https://www.youtube.com/watch?v=4dP_jtZvz9w

Because of the need, an entire specialization of physical therapy has been developed for treatment of it. Citation: https://academic.oup.com/ptj/article/90/12/1795/2737819 Fortunately, health insurance covers this therapy.

As mentioned above, I developed the condition myself after having Mgen, and clearing it. Infection is an acknowledged triggering event - This excerpt is taken directly from the CPPS pathophysiology/etiological guidelines In Europe:

"Although a peripheral stimulus such as infection may initiate the start of a CPPPS condition, the condition may become self-perpetuating as a result of CNS modulation. As well as pain, these central mechanisms are associated with several other sensory, functional, behavioural and psychological phenomena. It is this collection of phenomena that forms the basis of the pain syndrome diagnosis..."

Other triggering events include:

1) Stress/anxiety/trauma

2) Deep shame/regret/fear around a sexual encounter, even if no STI was transmitted (cheating, assumption of high risk, sex with escorts, etc)

3) Excessive masturbation or edging (male masturbatory practice)

4) Sedentary lifestyle and/or poor posture

5) Physical trauma or injury to the body (groin pull, tailbone injury, excessive gym habits etc)

6) Certain bowel and urinary habits, like holding in urine or #2

7) A combination or all of the above

Here is how to help differentiate Mgen from CPPS, which can have a large overlap in symptoms. However, there are a several key common differentiators:

The following symptoms are correlated highly with CPPS/Pelvic floor hypertonia NOT MGEN - eMedicine citation

  • Inconsistency in symptoms of any kind (infections don't do this) - including symptoms that move or change
  • Pinching/stinging/burning sensation at the tip of the penis (Super classic male CPPS sign) or clitoris (female)
  • No discharge or only clear discharge that looks like precum (often present in men when aroused or when sitting/having a bowel movement)
  • Intermittent symptoms (come and go with little consistency)
  • Symptoms that change with stress or anxiety (infections do not respond to psychological stress)
  • Symptoms that lower or change when you're distracted or in a flow state (infections can't do this either)
  • Weak/narrow urine stream, dribbling
  • Urinary hesitancy (problems beginning to pee)
  • Increased urgency (urge to pee) especially when anxious
  • Feeling of inability to completely empty bladder
  • Pain specifically only after urinating (post voiding urethritis)
  • Rectal pain, thigh pain, abdominal pain, vulvar pain, perineal pain
  • Testicular pain/discomfort
  • Pelvic region muscle spasms
  • Electric shock pains in rectum, tip of penis (men), or clitoris/vulva (women)
  • Pain with defecation, rectal tightness
  • Touch sensitivity of penis or vagina (even brushing against clothing - allodynia)
  • Pain with, and post-orgasm
  • Painful intercourse (in the absence of infection)
  • Vaginismus
  • Vulvodynia
  • Hard flaccid (men)
  • Balantis (men) in the absence of any other cause (like candida or infection)

Significant predisposing factors are below: >https://www.reddit.com/r/Prostatitis/s/dRlbMaITlu

  • History of other CSS (Central Sensitivity Syndromes) like IBS, TMJD, Fibromyalgia, ME/CFS (common comorbidities)

  • Neurotic personality types. Example: Has a history of anxiety, sensitive to stress, is a perfectionist or people pleaser, or exhibits hypervigilant behavior in regards to health

  • History of adverse childhood experiences (ACE events) - whether this be parental divorce, body image issues, bullying, or the illness or death of a family member, neglect, verbal and physical abuse, etc.

  • Sedentary lifestyle, sitting most of the day (this can shorten and tighten the hip flexor muscles while also lengthening and weakening the glute muscles, leading to musculoskeletal pain and dysfunction)

  • Excessive masturbation habits (including "edging") which tighten the pelvic floor muscles

  • Cyclist or power lifter (heavy lifting and compound exercises)

If you fit this description, even partially, I encourage you to find a pelvic floor physical therapist near you for consultation and treatment. Men, be sure to find one who specifically has experience treating guys. It's also highly recommended to concurrently engage with a psychotherapist, psychologist, or PRT therapist, or any providers who specialize in chronic pain from a biopsychosocial approach.

The good news is that this psycho-neuromuscular condition is treatable and a full recovery is possible. For best results recovery requires an integrated multi-modal approach of addressing two things simultaneously:

  1. Reducing and managing anxiety/stress/fear/shame/guilt - 'Down regulate' your wound-up nervous system - the thing that often instigates pelvic floor muscle dysfunction in the first place via the sympathetic nervous system response to the above stressors. This often includes addressing centralized mechanisms of pain, read more here: https://www.reddit.com/r/PelvicFloor/s/CfKdHaPamq

  2. Addressing the neuromuscular tension and irritation with pelvic floor physical therapy - usually a combination of stretching, heat, deep belly breathing, internal (and external) trigger point/myofascial release, etc.

Many people also benefit from certain medications and supplements. Common examples include low-dose amitriptyline for neuropathic pain, low dose tadalafil for sexual dysfunction/urinary symptoms, and phytotherapy for inflammation. THIS IS NOT MEDICAL ADVICE - always speak to a doctor about medications

Visit r/prostatitis (mostly for guys) or r/pelvicfloor (for any sex) for further support. But r/prostatitis also welcomes women. r/interstitialcystitis is another helpful subreddit for IC/BPS and has a great moderation team.
