In industrialised countries endometritis is a problem which represents an increasing risk to personal health and to society. In almost all cases the inflammatory process which affects the uterine mucosa forms part of a more generalised infection which involves the entire internal genital system (PID). The most important problem associated with pelvic phlogosis is increased sterility, a greater number of ectopic pregnancies and chronic pelvic pain. In order to treat the symptoms of genito-pelvic infection, an early diagnosis and adequate medical therapy are indispensable. In this event it may be possible to prevent invalidating effects on fertility and chronic pelvic pain.
