Gender Ethnicracial And Life Span Considerations

UTIs are uncommon in children. Once young and adult women become sexually active, the incidence of UTI increases dramatically. UTIs are common during pregnancy and are caused by the hormonal changes and urinary stasis that results from ureteral dilation. Men secrete prostatic fluid that serves as an antibacterial defense. As men age past 50, however, the prostate gland enlarges, which increases the risk for urinary retention and infection. As women age, vaginal flora and lubrication change; decreased lubrication increases the risk of urethral irritation in women during intercourse. By age 70, prevalence is similar for men and women. There are no known ethnic and racial considerations.
