This bacterium lives and multiplies inside the cells of the infected organism. It is transmitted to the infected partner during sexual intercourse and is also transmitted during oral and anal intercourse.
Of the three STDs, the most common is chlamydial infection, which affects the reproductive system. Chlamydial infection can occur with or without clinical symptoms, but regardless of the presence of symptoms, Chlamydial infection causes serious complications in the form of reproductive disorders and reproductive dysfunction in both sexes. It is a major pathogenic factor in male and female infertility. Transmission of the chlamydia agent occurs during sexual intercourse or through the infected genital organs at the birth of the child.
In women with long-term current, undetected and untreated infections, bacteria can invade the upper genital tract through the uterus, eventually leading to complications such as pelvic inflammatory disease, ectopic pregnancy, and fallopian tube blockage. In many cases, it causes no symptoms at all, but if it does, it takes the form of a pus-filled vaginal discharge.
In men, complications of Chlamydia infection can include testicular and epididymitis and sexually acquired reactive arthritis. In men, chlamydial infection is also associated with a reduction in reproductive capacity due to direct effects on sperm maturation, mobility, and viability. Symptoms include burning sensation when urinating, pain, discharge from the urethra, and discomfort around the testicles.
