What are the health problems associated with Chlamydia?

• In women, chlamydia usually begins with an inflammation of the cervix. The long-term health effects of chlamydia remain unclear. The medical profession speculates that chlamydia could be a cause of sterility in women if the chlamydia infection were to spread into the uterus and tubes, causing a pelvic infection and scarring in the tubes. Many women that have chlamydia and do get PID and not all women with PID have a chlamydia infection.
• Chlamydia is passed to sexual partners during unprotected intercourse.
• A woman can also transmit chlamydia to her infant during birth. This can cause pneumonia if it spreads to the lungs or blindness if it infects the eyes.
• In men, chlamydia may cause urethritis, which is an inflammation of the urethra referred to as NGU or NSU. If this remains untreated, it may also cause sterility in men.
