Women often urinary tract infections, there are urethral factors, estrogen levels, unclean sex life and other aspects of the reasons, as follows: First, urethral factors: female urethra is shorter than male urethra, the female urethra is about 6-8cm, while the male urethra is about 17-20cm, so the chances of women suffering from urinary tract infections is greater than men. Physiologically speaking, the urethra of women is closer to the vagina and anus, so the chances of urinary tract infections will be relatively greater. Second, estrogen levels: If you are an older woman, as you age, your body estrogen levels decline, which will lead to a corresponding decrease in immunity, which will also cause urinary tract infections. Third, unclean sex life: the couple’s sexual life is not clean, is also a relatively major factor causing urinary tract infections in women, so it is very important to keep the perineal area clean and clean.
