75% of cases of chlamydia infection in men and 50% of cases in women occur without symptoms. Such can appear within 1-3 weeks after sexual contact. Symptoms in women are: abnormal vaginal discharge that may have an odor, bleeding between menstrual cycles, painful cycle, abdominal pain with high fever, pain during sex, itching or burning of the vagina, pain when urinating. Symptoms in men: painful urination, burning and itching at the opening of the urethra, pain and swelling around the testicles, etc. NEWS_MORE_BOX If the infection is not treated, the risk of a number of health problems increases. In women, chlamydial infection can lead to pelvic inflammatory disease, which in turn causes blockage of the fallopian tubes and infertility. Complications from the infection also increase the risk of ectopic pregnancy and premature birth. In men, untreated chlamydia can cause the development of urethral infection, epididymitis (inflammation of the appendage of the testicle) or proctitis (inflammation of the rectum). To limit the risk of chlamydia, it is important to use a condom during sexual intercourse. If symptoms are present, sex should be avoided. A visit to a specialist doctor for an examination and conducting tests is mandatory.
