The organism causes genitourinary infections in both women and men and may be associated with dysuria as well as vaginal, urethral, or rectal discharge. In women, complications include pelvic inflammatory disease, salpingitis, and infertility. Approximately 25% to 30% of women who develop acute salpingitis become infertile. Complications in men are rare but can include epididymitis and sterility. Rarely, genital chlamydial infection can cause arthritis with associated skin lesions and ocular inflammation (Reiter syndrome). C. trachomatis can be transmitted from the mother during delivery and is associated with conjunctivitis and pneumonia. Finally, C. trachomatis may cause hepatitis and pharyngitis in adults.
