Context Most Pages Skip

Chlamydia trachomatis is a common bacterial sexually transmitted infection that often causes no symptoms in men. When left untreated, the bacteria can travel from the urethra to the epididymis, the tube that stores and carries sperm. This can trigger inflammation and scarring, potentially blocking sperm from reaching the semen. Because many men do not realize they have chlamydia, the infection can silently damage fertility over time. Understanding this mechanism is key to preventing infertility and protecting both your own reproductive health and your partner's pregnancy.
