Most of the current Mycoplasma urealyticum infections are caused by unclean sexual contact, and some are secondary to contact with the secretions of infected patients. Mycoplasma urealyticum is a pathogenic microorganism and is the most common microorganism that can cause infections in the male and female genital tract and urinary tract. If the presence of Mycoplasma decidua infection is considered, urine culture, culture of secretions, and PCR testing can be used to clarify the status of Mycoplasma decidua infection. If the infection is present, sensitive antibiotics such as macrolide antibiotics such as azithromycin and roxithromycin can be used. During the treatment period, alcohol and spicy food should be avoided, and couples should be treated at the same time.
