Sex, Drugs and Stinky Urine: ALL the Sex-Related Causes of Smelly Pee

Sex, Drugs and Stinky Urine: ALL the Sex-Related Causes of Smelly Pee

STDSexually Transmitted Diseases and Stinky Pee

Some sexually transmitted diseases (STDs) cause foul smelling urine. Many others cause symptoms often mistaken for stinky pee at first, such as those that cause foul-smelling discharge. Examples of STDs that may cause smelly urine include Trichomoniasis, Chlamydia and Gonorrhea.

Sexual activity can also increase the chances that you develop a urinarty tract infection or yeast infection, both of which are associated with foul odors.

Can an STD Make My Urine Stink?

If you’ve recently had unprotected sex and you’re now experiencing stinky urine each time you head to the bathroom, you could be suffering from a sexually transmitted disease (STD).

Now, if you just had sex last night and you’re worrying like crazy because you’ve got stinky pee or a slight burning sensation, don’t jump to conclusions. Most STD’s won’t begin exhibiting symptoms until a few days after exposure. There could be other possible reasons for your urine odor, such as a yeast infection or urinary tract infection (UTI). In any event, you should definitely check with your physician and get tested if you think the main culprit behind your stinky urine could be an STD.

Infections of any sort can be associated with smelly urine, and most STDs are considered infections. The three most common STDs that could cause stinky pee are Chlamydia, gonorrhea and Trichomoniasis. Below you will find detailed information about each of these.


One of the STDs that causes smelly pee is trichomoniasis. Trichomoniasis is an infection of a protozoan parasite called Trichomonas vaginalis. The infection is usually in the vagina and/or in the urethra. This parasite kills its hosts’ cells and then consumes the pieces.

Both males and females can get trichomoniasis, but the symptoms are more noticeable in women. Symptoms women commonly experience include:

  • Itching, burning or inflammation of the cervix, vagina or urethra
  • Pain or discomfort during sex
  • Pain or discomfort when urinating
  • Vaginal discharge that is yellowish green, frothy and smells fishy
  • Foul-smelling urine
  • Lower abdominal pain (which is uncommon)

Trichomoniasis in Men

Many men who have trichomoniasis will have no symptoms at all. Symptoms that men may experience include:

  • Irritation in the penis
  • Discharge
  • Irritation or burning after ejaculating or urinating

Symptoms in men (if any) tend to go away, but this does not necessarily mean the infection has gone away.

The only treatment for trichomoniasis is a prescription antibiotic. Metronidazole is the antibiotic typically used, but your doctor may prescribe a different medication.


Whether you’re male or female, if your urine smells, you may have trichomoniasis, an infection caused by Trichomonas vaginalis (a parasite). The condition nearly always occurs in the vagina, the urethra, or both. What makes this such a pernicious parasite is that it kills and consumes its host cells.

While you may think that you’ve become infected with this STD after some recent sexual activity that wasn’t protected, you may be wrong. Symptoms won’t usually begin appearing in women until 5 days after being exposed to the parasite, and may not show themselves for as long as 28 days following exposure. And when men become infected, they may not know it for years.

Trichomoniasis Symptoms in Women

While men can also get trichomoniasis, it is more rare, and women are most likely to experience its symptoms. Many of the symptoms are similar to the flu, but if you are experiencing one or more of them, and think you may have been infected through sexual intercourse, you should schedule an appointment with a physician.

Symptoms that women often experience include:

  • Itching, burning or inflammation of the cervix, vagina or urethra
  • Pain or discomfort during sex
  • Pain or discomfort when urinating
  • Vaginal discharge that is a yellowish-green, cloudy or frothy, and smells fishy
  • Foul-smelling urine
  • Lower abdominal pain (which is less common)

Treatment for Trichomoniasis

Treating trichomoniasis requires prescription antibiotics. Metronidazole is the antibiotic usually used, but your doctor may give you a different medication based on your needs and the severity of your condition.

Men have a much easier time when it comes to trichomoniasis exposure. Their bodies have a good chance of expelling the parasite altogether within 14 days of exposure. Women, however, must be treated or the condition will persist.

Further Complications

Studies have shown that trichomoniasis may lead to other problems and complications later in life. These include:

  • An increased risk of transmitting HIV
  • Women may deliver their infant prematurely, or with a low birth weight
  • Those infected have an increased risk of developing cervical cancer
  • Men with the condition have an increased risk of developing prostate cancer

The good news is that trichomoniasis is completely preventable by engaging in safe sexual practices. Using condoms will greatly reduce your risk of getting this and many other STDs.

Other Sexually Transmitted Diseases

If you suspect you have an STD, you should see your doctor as soon as possible. It is important that you establish that you are disease-free, or if you have an STD, receive treatment.

You should make it a point to get tested for STDs if you have had unprotected sex. One way to accomplish this if you can’t see your doctor is to try an at-home test for sexually transmitted diseases such as HIV or Gonorrhea and Chlamydia.


In some cases, the sexually transmitted infection Chlamydia can cause stinky urine. Chlamydia is an infection of the bacteria Chlamydia trachomatis. It usually affects the genitals or the eyes. The disease is more common than other STDs, with about 1 million people in the US having it. Chlamydia is typically transmitted through sexual intercourse (including vaginal, anal and oral), but can also be transmitted to a baby during childbirth if the mother has it.

Most women who have Chlamydia do not know it, as it is often asymptomatic for women. Men usually have symptoms, especially white discharge from the penis and possibly pain when urinating. Regardless of gender or whether you have symptoms, it is important to get this STD treated. It can cause pelvic inflammatory disease in women and testicular pain in men. If left untreated, Chlamydia can cause problems with the reproductive system.

Symptoms of Chlamydia in Women It is not uncommon for women with Chlamydia to notice no symptoms. Anywhere from 50 to 80% of women experience no signs or symptoms of the disease. However, untreated Chlamydia is still a concern, since it can lead to pelvic inflammatory disease. PID can cause scarring in the uterus, fallopian tubes or ovaries, leading to infertility, ectopic pregnancies and pregnancy complications. Women with Chlamydia are also five times more likely to contract HIV if they are exposed to it. When symptoms do occur, they may include the following:

  • Vaginal bleeding
  • Vaginal discharge
  • Abdominal pain
  • Fever
  • Pain during sex
  • Pain when urinating
  • Frequently feeling the urge to urinate

Symptoms of Chlamydia in Men

About half of all men with Chlamydia will have inflammation of the urethra. This manifests as pain or burning when urinating, a light-colored discharge coming from the penis, fever and tender (or swollen) testicles. Without treatment, Chlamydia can spread to the testicles, causing pain. In some cases, this may also cause sterility.

Diagnosing Chlamydia

Your doctor can have you tested for Chlamydia. This involves either taking a swab of the inside of the penis or cervix or testing your urine. It is also possible to test yourself for Chlamydia using an at-home test kit.

Treatment for Chlamydia Prescription antibiotics are the treatment for Chlamydia. The infection is completely cured by antibiotics. If you have a partner, you should have him/her treated as well to avoid re-infection.

Don’t forget that antibiotics can sometimes cause smelly urine.


Gonorrhea, also known as “The Clap” is a bacterial infection that is sexually transmitted. In men, typical symptoms are burning when urinating and discharge coming from the penis. Women sometimes do not have symptoms, but when they do, pelvic pain and vaginal discharge are common. It is important to seek treatment if you suspect you have Gonorrhea because it can lead to pelvic inflammatory disease in women or infection spreading to the testicles for men. The infection can also spread to the rest of the body, which could cause problems with heart valves or joints.

Symptoms of Gonorrhea Up to half of all women with gonorrhea have no symptoms. Those who do have symptoms may notice the following:

  • Pain in the lower abdominal area
  • Vaginal discharge
  • Pain during sex

Men who have gonorrhea may have symptoms such as pain/burning when urinating or discharge from the penis. Both men and women may have the following symptoms:

  • Sore throat (if infection of the throat occurred)
  • Skin lesions (rare)
  • Joint pain and swelling (rare)

Oral sex can transmit gonorrhea and cause an infection of the throat. This sort of infection most often causes no symptoms. In the 10% of people who do show symptoms of a gonorrhea throat infection, a sore throat is noted. Most symptoms appear within 4 to 6 days after acquiring the infection, but gonorrhea’s incubation period is anywhere from 2 to 14 days. Although it is rare, people with compromised immunity can suffer from the infection spreading to their heart or spinal column.

Tests for Gonorrhea

Your doctor can have you tested for gonorrhea and other STDs. You can also test yourself using an at-home test kit.

Treatment for Gonorrhea

Gonorrhea is treated with antibiotics. However, it is beginning to become resistant to antibiotic treatment, so your doctor will have to decide which antibiotic is best.

Your partner should also be treated for gonorrhea at the same time you are.

Almost half of all people with gonorrhea also have Chlamydia, which is the most common STD in the US.
