What are the signs and symptoms of STDs in men?
In men, STDs can be grouped into three categories:
STDs that predominantly cause genital lesions (sores or abnormalities on the genital organs)
STDs that predominantly cause inflammation of the urethra (urethritis)
STDs that cause symptoms and signs throughout the body (systemic STDs)
Some of the STDs that cause local lesions or urethritis, including gonorrhea and syphilis, can also cause damage to other organs and spread within the body if not treated.
Depending upon the exact infection, STDs that cause genital lesions may cause genital warts, painful blisters, or ulcers. STDs that cause urethritis cause symptoms often associated with a urinary tract infection, including painful or burning sensation during urination and discharge from the urethra.
