Urinary tract infections in women may have something to do with their boyfriends. If the male partner has a circumcised glans or suffers from a urinary tract infection, during sex, the woman is likely to have a retrograde infection of bacteria through the urethra as a result, leading to a urinary tract infection. As women have a lot of bacteria around the vagina as well as the anus, and the urethra is very close to the vagina and anus. If the man has a condition such as prepuce glans, he may transmit the free bacteria to the woman through sex, which will lead to urinary tract infection in the woman. It manifests itself in symptoms such as frequent urination, urinary urgency, painful urination and fever. When a female patient has symptoms of urinary tract infection, she should consult a doctor in time, under the guidance of a professional doctor, to clarify the cause of the disease to choose targeted treatment.
