What Is Chlamydia?
What Are Symptoms of Chlamydia for Men vs. Women?
Most people infected with Chlamydia have no symptoms, which can make it easy to spread the infection. When symptoms do occur, they can range from mild to severe.
Up to 70 percent of men with Chlamydia have no symptoms. When symptoms do occur in men, they may include:
- Discharge from the penis
- Burning or pain with urination
- Testicular pain or tenderness
- Swelling in the scrotum
Up to 90 percent of women with chlamydia have no symptoms. When symptoms do occur in women, they may include:
- Vaginal discharge
- Abnormal vaginal bleeding
- Abdominal pain
- Painful sexual intercourse
- Burning or pain with urination
Men and women who have anal sex with infected men can develop chlamydia infection in the rectum or anus.
Chlamydia may also cause an inflammation of the conjunctiva (conjunctivitis) if a person is exposed to semen or vaginal discharge from an infected person.
In rare cases, people with chlamydia can develop reactive arthritis which can cause seemingly unrelated symptoms, including:
What Causes Chlamydia?
Risk factors that increase the chance of getting Chlamydia include:
- A new sexual partner
- Having more than one sexual partner
- Having a previous chlamydia infection and having sex with a partner who has not been treated for the infection
How Is Chlamydia Diagnosed?
Chlamydia is diagnosed with a urine sample or with a swab of fluid from the vagina or cervix (in women), from the urethra (in men), or from the rectum in women and men.
Results are usually available within 24 hours.
What Is the Treatment for Chlamydia?
Other antibiotics may be used if patients are unable to take azithromycin, such as:
- Doxycycline 100 mg orally twice a day for 7 days
- Erythromycin base 500 mg orally four times a day for 7 days
- Erythromycin ethylsuccinate 800 mg orally four times a day for 7 days
- Levofloxacin 500 mg orally once daily for 7 days
- Ofloxacin 300 mg orally twice a day for 7 days
Patients are advised to avoid sex for seven days after completing the antibiotic treatment.
Sexual partners should also be treated. All sexual partners of the patient in the last 60 days should be tested for Chlamydia, even if they do not have symptoms. It is possible to be re-infected with Chlamydia, and the most common reason this occurs is when sexual partners are not treated.
After treatment, patients should be re-tested for Chlamydia about three months after their diagnosis because many people are re-infected from untreated sexual partners.
What Are Complications of Chlamydia in Men and Women?
Complications of Chlamydia in women include:
- Pelvic inflammatory disease (PID), which can cause scarring of the fallopian tubes, possibly leading to infertility and an increased risk of ectopic pregnancy
- Serious problems in pregnancy, including miscarriage and premature birth
- Pregnant women can pass the infection on to their baby during delivery, which can cause:
Complications of Chlamydia in men include:
