Gonorrhea is a common sexually transmitted infection caused by Neisseria gonorrhoeae bacteria. These bacteria can grow and multiply easily in the warm, moist areas of the reproductive tract, including the cervix (opening to the womb), uterus (womb), and fallopian tubes (egg canals) in women, and in the urethra (urine canal) in women and men. The bacteria can also grow in the mouth, throat, eyes, and anus. Gonorrhea is spread through contact with the penis, vagina, mouth, or anus. Ejaculation does not have to occur for gonorrhea to be transmitted or acquired. Gonorrhea can also be spread from mother to baby during delivery. Infection can cause serious reproductive health problems, such as pelvic inflammatory disease (PID) and infertility. Gonorrhea also can cause infections in newborn babies. Tests and effective treatments are available.
