Women’s urinary tract infections may be transmitted to men, so when women’s urinary tract infections are treated, it is generally recommended not to have intercourse, and to resume intercourse after the urinary tract infection is completely cured. From the specific etiology of the infection, female urethral infections can be broadly divided into common bacterial infections, gonococcal infections, mycoplasma, chlamydia infections, etc.: 1. Common bacterial infections: common pathogenic bacteria, such as Escherichia coli, Staphylococcus aureus and Proteus, such bacteria in the process of intercourse, especially when men are not wearing condoms, it is possible to bring these bacteria from the vagina, urethra to men This can lead to glans penis and urinary tract infection in men. In the treatment is usually preferred quinolone antibiotics, such as levofloxacin for treatment; 2, gonococcal infection: gonococcal infection, or gonorrhea, is a sexually transmitted disease, or STD. This type of infection often causes yellowish-white pus to flow from the external urethra of both men and women, and itching will also occur at the external urethra. At this point, pathogen identification can be improved and if gonococcus is confirmed, it is recommended that high doses of penicillin or cephalosporin antibiotics be given for treatment. During the treatment period, intercourse should be strictly prohibited, otherwise it is easy to cause cross-contamination; 3, mycoplasma, chlamydia infection: mycoplasma, chlamydia infection can cause non-gonococcal urethritis. The actual woman is particularly susceptible to mycoplasma and chlamydia infections, and when women have gynecological infections or urethral infections, they are prone to bring these pathogens to men, causing non-gonococcal urethritis in men. The clinical manifestations are not only frequent, urgent and painful urination, but also increased discharge from the external urethra, which is usually thin. After the pathogen test is done to clarify the diagnosis, it is recommended to give macrolide antibiotics for treatment.
