Male chlamydia can damage a woman's reproductive organs. Even though symptoms of chlamydia are usually mild or absent, serious complications that cause irreversible damage, including infertility, can occur "silently" before a woman ever recognizes a problem. Chlamydia also can cause discharge from the penis of an infected man.

Untreated chlamydia infection can cause many problems. If untreated, chlamydia infection can progress to serious reproductive and other health problems with both short-term and long-term consequences. Like the disease itself, the damage that chlamydia causes is often silent.

Risks among men are rare. Infection sometimes spreads to the epididymis (the tube that carries sperm from the testis), causing pain, fever, and, rarely, sterility. Thus, untreated chlamydia in men can cause epididymitis and prostatitis.

In women, untreated chlamydia infection can spread into the uterus or fallopian tubes and cause pelvic inflammatory disease (PID). Chlamydia can also cause fallopian tube infection without any symptoms. PID and silent infection in the upper genital tract can cause permanent damage to the fallopian tubes, uterus, and surrounding tissues. The damage can lead to chronic pelvic pain, infertility, and potentially fatal ectopic pregnancy (pregnancy outside the uterus). Chlamydia may also increase the chances of becoming infected with HIV, if exposed.
