Neisseria gonorrhoeae is a bacterial infection that can cause inflammation of the reproductive tract and lead to infertility if left untreated. This bacterium can infect the cervix, uterus, and fallopian tubes in women, causing pelvic inflammatory disease (PID). PID can damage the reproductive organs and cause scarring, which can block the fallopian tubes and prevent fertilization. If fertilization does occur, the damaged tubes may increase the risk of ectopic pregnancy. It is essential to get tested and treated for this infection promptly to prevent long-term complications.
