STDs in men are generally diseases caused by viruses fungi and bacteria. STDs caused by bacteria can usually be cured with antibiotics, while some STDs, such as herpes and HIV infection, these diseases cannot be cured and survive for life. In men, there are three main types of STDs: those that cause genital damage, those that cause inflammation of the urinary tract, and those that cause systemic signs and symptoms. Some localized lesions or STDs of the urethra, including gonorrhea and syphilis, can also cause damage to other organs of the body if left untreated. Most STDs in men are transmitted through sexual intercourse. There are some STDs that some people may not know they have and unknowingly transmit such diseases to others, such as AIDS. The only way to avoid these diseases is to abstain from sexual activity or use safety measures. But the main thing is to be clean. STDs are diseases caused by the transmission of pathogens such as bacteria, viruses and fungi through sexual contact. Therefore, you must pay attention to avoid impure sex and do a good job of protection during sex.
