Gonorrhea is a sexually transmitted disease caused by the transmission of a bacteria. Like many other STDs, gonorrhea can hide from the immune system and an infected person can remain infected indefinitely, although the person may not always be contagious. In addition, the consequences of being infected by gonorrhea are less serious than those caused by syphilis, although the disease can cause sterility if untreated. Unlike the syphilis bacteria, gonorrhea is unable to penetrate the skin, so must attack weaker tissues, generally the urethra in males and the cervix in females. Gonorrhea website
