Ever wondered what chlamydia smells like? No? Just us? Well, when it comes to your vaginal health, it's essential to know what’s normal and what isn’t. Chlamydia, one of the most common sexually transmitted infections (STIs), often flies under the radar because it doesn’t always cause noticeable symptoms. But when it does, one potential red flag is a change in the way your vaginal discharge smells. But what does chlamydia discharge smell like?

If you’re curious or worried, we’re here to clear the air on what chlamydia discharge smells like so you can sniff out (pun intended) any problems before they get serious.

What is chlamydia?

Chlamydia is a common sexually transmitted infection caused by the bacterium Chlamydia trachomatis. It’s particularly common among sexually active women. Chlamydia spreads through unprotected sex (including vaginal, oral, and anal sex, or by sharing sex toys) with an infected person. It’s often known as the “silent” infection because up to 80% of women with chlamydia may not experience any symptoms at all.

When symptoms do show up, they typically appear within one to three weeks after exposure, but sometimes, they can take longer. An untreated chlamydia infection can cause serious complications, such as pelvic inflammatory disease (PID), infertility, and ectopic pregnancy.

Chlamydia symptoms

While chlamydia often goes undetected due to its lack of symptoms, it’s still helpful to know what to look for:

  • Unusual vaginal discharge that is white, yellow, and has a foul smell 
  • A burning sensation when you pee
  • Pain during sex
  • Pelvic pain
  • Spotting or bleeding between periods
  • Fever (in rare cases).

What does chlamydia discharge smell like?

The smell of chlamydia discharge can be subtle or even absent. However, when it’s present, it’s often described as:

  • Foul or unpleasant
  • Fishy or musty
  • Sharp or pungent.

It's important to note that chlamydia discharge doesn’t always have a distinct smell. A foul odor may not automatically mean chlamydia, as other infections or conditions can also cause smelly vaginal discharge. If you notice an unpleasant odor, it’s a good idea to see a healthcare provider for an accurate diagnosis.

Other causes of foul-smelling vaginal discharge

An unusual or foul-smelling discharge isn’t always due to chlamydia. Several other conditions can also cause changes in the appearance or smell of vaginal discharge:

  1. Bacterial vaginosis (BV): BV is a common bacterial infection that occurs when there’s an imbalance of bacteria in the vagina. The discharge associated with BV is often thin, grayish, and has a strong fishy odor. It can sometimes be mistaken for chlamydia, but they are different infections and require different treatments.
  2. Trichomoniasis: This sexually transmitted infection is caused by a parasite and can lead to frothy, yellow-green discharge with a strong, unpleasant smell. Trichomoniasis can cause symptoms similar to chlamydia, so it’s important to get tested to determine the correct treatment.
  3. Yeast infections: A vaginal yeast infection can cause a thick, white discharge that resembles cottage cheese. Although this type of infection typically doesn’t have a strong odor, some women may notice a slight “yeasty” smell.
  4. Pelvic inflammatory disease (PID): PID is a serious complication that can arise from untreated STIs like chlamydia. It can lead to foul-smelling discharge, along with pelvic pain, fever, and other symptoms. PID requires prompt medical attention, as it can damage reproductive organs and affect fertility.
  5. Forgotten tampons: Occasionally, a foul odor may result from non-infectious causes, such as poor hygiene or forgetting to remove a tampon. 

When should you see a doctor?

If you experience any unusual symptoms, including foul-smelling discharge, it’s important to seek medical advice. Bacterial infections — whether or not they’re sexually transmitted — require antibiotic treatment to prevent complications. It’s always best to consult a healthcare professional who can perform the necessary tests to diagnose and treat the issue.

You should see a doctor if you notice unusual discharge accompanied by:

  • Painful urination
  • Vaginal itching or irritation
  • Painful sex
  • Lower abdominal pain or cramping
  • Unexplained vaginal bleeding between periods or after sex
  • Fever or chills. 

How to prevent chlamydia and other STIs

The best way to lower your risk of contracting (or spreading) chlamydia and other STIs is to practice safe sex. Here are some tips to keep in mind:

  • Use condoms consistently and correctly during vaginal, anal, and oral sex.
  • Use dental dams during oral sex with a vagina.
  • Wash sex toys before and after use, and cover them with a condom during partnered sex.
  • Get tested regularly, especially if you have multiple sex partners or a new partner.
  • Communicate with your sexual partners about STI testing.

Chlamydia infections are common and treatable, but it’s important to recognize the signs and get tested if you suspect something isn’t right. The Centers for Disease Control and Prevention recommends getting tested for chlamydia every year if you're sexually active and younger than 25, or have new or multiple sexual partners.

FAQ

Does chlamydia discharge have an odor?

Chlamydia discharge may not always have a noticeable odor. Sometimes, chlamydia doesn't cause any symptoms, so you might not notice any changes in discharge at all. However, when unusual discharge does happen, it might have a mild to unpleasant smell, which could be described as foul, musty, or even fishy. It's important to note that the presence or absence of an odor alone isn’t a reliable indicator of chlamydia, as other infections, like bacterial vaginosis or trichomoniasis, are more commonly associated with a strong odor. If you notice unusual discharge, it's important to get tested for a proper diagnosis. You can get tested for chlamydia at your doctor's office, or take an at-home chlamydia test with Evvy. An Evvy test can detect four of the most common STIs, along with over 700 different bacteria and fungi responsible for unusual discharge.

What does chlamydia discharge look like?

Chlamydia can cause yellow, white, thick, or milky vaginal discharge that has a strong, unpleasant smell. However, discharge can vary from person to person, so it's important to pay attention to any noticeable changes in the color, consistency, or smell of your vaginal discharge. Sometimes, the symptoms of chlamydia can be hard to identify since the changes are often subtle and can easily be confused with other vaginal infections, such as BV or a yeast infection. That’s why routine STI testing is essential. Keeping track of your vaginal health can help you detect any problems early and receive the right treatment.

Does chlamydia make pee smell?

While chlamydia itself doesn't typically cause urine to smell, it can lead to inflammation in the urinary tract, which may result in symptoms like burning during urination and occasionally, an unusual or stronger odor. If you notice a strong, foul, or unusual smell in your urine, it could be a sign of a urinary tract infection (UTI) or another condition like BV that may occur alongside chlamydia. If you experience persistent changes in the smell of your urine, it's essential to consult a healthcare professional for a proper diagnosis and testing.
