There are actually some reasons why women are prone to gynecological bacterial infections. First of all, women in their reproductive years have a more frequent sexual life or are more tired because of work or study, and their body resistance is poorer. Other women have a cleanliness fetish, such as repeatedly douching the vagina every day, thinking that this is cleanliness, but it is not. There are also some women, mainly women after menopause, who have lower estrogen levels in their bodies, such as after menopause when ovarian function declines and estrogen levels decrease, or in young children when ovarian function has not started to develop and estrogen levels are also low, which can cause specific vaginal inflammatory diseases. For example, vaginitis in infants and children, and vaginitis in the elderly after menopause, are caused by lowered estrogen levels. In some women, after childbirth, there is a relaxation of the pelvic floor muscles, causing a relaxation of the vaginal wall, which cannot close the vagina completely and can also induce the appearance of bacterial infections in women, which can recur.
