Chlamydia Symptoms: Signs in Men & Women

Chlamydia is an incredibly common—and curable—bacterial STI. But because it often shows no symptoms, a comprehensive lab test is the only way to know your status for sure.

The Challenge of a 'Silent' Infection

Chlamydia is one of the most common sexually transmitted infections (STIs) in the United States, caused by the bacterium Chlamydia trachomatis (per MedlinePlus). It is easily curable with antibiotics. The biggest challenge, however, is its nature as a “silent” infection.

Most people who have chlamydia show no symptoms at all. (per CDC)

Without any noticeable signs, a person can carry and transmit the infection to partners for months or even years. Over time, an untreated chlamydia infection can lead to serious and sometimes permanent health complications, particularly for women (per ACOG).

This is why relying on symptoms to decide whether to get tested is a risky approach. Understanding the potential signs, the risks of leaving it untreated, and the importance of regular screening is fundamental to protecting your sexual health.

Understanding Chlamydia Transmission and Prevalence

Chlamydia is a bacterial STI that can infect people of all genders. It's the most frequently reported bacterial infectious disease in the U.S.; in 2022, there were more than 1.6 million cases reported to the Centers for Disease Control and Prevention (per CDC). Due to the high rate of asymptomatic infections, the actual number of cases is likely much higher.

The infection is spread through vaginal, anal, or oral sex with an infected partner. A pregnant person can also pass the infection to their baby during childbirth (per ACOG). Because it is so common and silent, major health organizations recommend routine screening for groups like sexually active women under 25 to catch infections early (per CDC).

Recognizing Chlamydia Symptoms (When They Appear)

While many people will never develop symptoms, it's important to know what to look for. When chlamydia symptoms do occur, they usually appear one to three weeks after initial exposure (per Mayo Clinic). The signs can also be very mild and easy to dismiss as something else, like a urinary tract or yeast infection.

In my practice, I often see patients who are surprised by a positive chlamydia result. Many only get tested because a new partner requested it, discovering an infection they've likely had for months without a single symptom. This illustrates why we can't rely on our bodies to tell us when to test.

Symptoms can vary based on the site of the infection and a person's anatomy.

Chlamydia Symptoms in Women

When symptoms are present in women, they are often mild. They can include:

• Abnormal vaginal discharge that may be yellowish or have a strong odor
• A burning sensation during urination
• Pain during sexual intercourse
• Bleeding between periods
• Lower abdominal pain
• Rectal symptoms like pain, discharge, or bleeding

If the infection spreads, it can cause a serious condition called Pelvic Inflammatory Disease (PID), which has its own distinct symptoms like fever and severe pelvic pain (per CDC, Mayo Clinic).

Chlamydia Symptoms in Men

Men are slightly more likely to have symptoms than women, but many still have none. When symptoms do appear, they can include:

• Discharge from the penis that is watery or milky
• A burning sensation during urination
• Pain and swelling in one or both testicles (less common)
• Rectal symptoms such as pain, discharge, or bleeding

(per CDC, Mayo Clinic)

Symptoms in Other Body Parts

Chlamydia can also infect the throat or eyes through oral sex or contact with infectious fluids. A throat infection is almost always asymptomatic but can occasionally cause a sore throat (per CDC). An eye infection can cause redness, itching, and discharge (conjunctivitis).

The Dangers of Untreated Chlamydia

The reason healthcare providers stress the importance of screening is because of the serious, often irreversible complications that can arise if the infection is left untreated.

Risks for Women: PID and Infertility

For women, the most significant risk is developing Pelvic Inflammatory Disease (PID). This occurs when the bacteria travel from the cervix into the uterus and fallopian tubes. PID can cause permanent scarring and damage to the female reproductive system.

This damage can block the fallopian tubes, which is a direct cause of infertility. It also dramatically increases the risk of an ectopic pregnancy—a life-threatening condition where a fertilized egg implants outside the uterus. Chronic pelvic pain is another long-term consequence of PID (per CDC).

Risks for Men and During Pregnancy

For men, while complications are less frequent, they can still be serious. The infection can spread to the epididymis (the tube carrying sperm), causing a painful condition called epididymitis. In rare cases, this can lead to infertility (per Mayo Clinic).

For pregnant individuals, untreated chlamydia can lead to preterm delivery. It can also be passed to the baby during birth, causing eye infections or pneumonia in the newborn (per ACOG). Furthermore, having an active chlamydia infection can increase a person's risk of acquiring or transmitting HIV (per CDC).

Clinic Visit vs. Private Lab Testing

When you need to get tested, you have options. It's helpful to see how the traditional clinic experience compares to ordering your own lab-drawn test.

Feature	Traditional Clinic Visit	LabTestsOnDemand (at Labcorp)

Why Testing for Only Chlamydia Isn't Enough

Given the risks, getting tested seems straightforward. But testing only for chlamydia is often not the safest or most effective choice for two key reasons.

1. Overlapping Symptoms: The potential signs of chlamydia—like painful urination or unusual discharge—are not unique. They can also be caused by other common STIs like gonorrhea or trichomoniasis.

2. Co-infections are Common: It's very common for people to have more than one STI at the same time. The behaviors that put you at risk for one put you at risk for others. A comprehensive screen provides a complete and accurate picture of your health.

For these reasons, a full panel test is the clinical standard for responsible STI screening.

Get a Complete Picture: The Importance of Panel Testing

At LabTestsOnDemand, we've designed our service around what's most clinically sound and private for you. We only offer comprehensive screening panels because a single test can provide a false sense of security.

If you'd rather skip the clinic visit and get a complete, confidential picture of your health, you can order the $189 Standard STI Panel and walk into any Labcorp for sample collection. It covers seven of the most critical infections with a single blood draw and urine sample:

• Chlamydia
• Gonorrhea
• Hepatitis B
• Hepatitis C
• HIV (Type 1 & 2)
• Syphilis

For an even more complete screen, our Comprehensive STI Panel adds testing for Herpes Simplex Virus 1 & 2 and Trichomoniasis. This is a fully private, self-pay service. You don't need a doctor's exam, and because we don't involve insurance, no claim is filed.
