Chlamydia is a sexually transmitted genital infection and is manifested in males primarily as urethritis and in

females as mucopurulent cervicitis. Clinical manifestations of urethritis are often difficult to distinguish from

gonorrhea and include mucopurulent discharges of scant or moderate quantity, urethral itching, and burning on

urination. Possible complications or sequelae of male urethral infections include epididymitis, infertility, and Reiter

syndrome. In homosexual men, receptive anorectal intercourse might result in chlamydial proctitis. In women, the

clinical manifestations might be similar to those of gonorrhea and frequently present as a mucopurulent endocervical

discharge, with edema, erythema, and easily induced endocervical bleeding caused by inflammation of the

endocervical columnar epithelium. However, up to 70% of sexually active women with chlamydial infections are

asymptomatic. Complications and sequelae include salpingitis with subsequent risk of infertility, ectopic pregnancy,

or chronic pelvic pain. Asymptomatic chronic infections of the endometrium and fallopian tubes might lead to the

same outcome.Physiological Adaptation
