Untreated Gonorrhea can cause strictures (narrowing) in the urethra requiring the use of a metal sound to stretch and reopen the urethra. A condition called balanitis in males is also common. Additionally, it can advance beyond the urethra to cause infection and inflammation of the reproductive organs in both males and females sometimes resulting in infertility. Rarely, it can travel through the bloodstream and lead to meningitis, endocarditis and a type of arthritic joint disease.
I wouldn’t take gonorrhea lightly – Get appropriately treated!
