Mycoplasma infection can be transmitted through sexual contact but is not strictly an STD. Mycoplasma is the smallest microorganism that lives outside the cell, a class of prokaryotic cellular microorganisms that lack a cell wall, unlike bacteria and viruses, and are diverse and widely distributed. Mycoplasma urealyticum, Mycoplasma humanum, and Mycoplasma genitalium are pathogens that cause human genitourinary tract infections and can be transmitted through sexual contact, causing urethritis, prostatitis, and other genitourinary tract infections. The pathogenicity of mycoplasma is not very clear, and can be transmitted through sexual intercourse, as well as through clothing and shared hygiene products. Therefore, mycoplasma infection is not strictly a sexually transmitted disease. Patients diagnosed with mycoplasma infection should be treated under the guidance of a doctor, and during the treatment period, pay attention to eating less spicy and stimulating food and eating as light as possible.
