Not all women get vaginal inflammation, but women are relatively susceptible to vaginal inflammation for several reasons: 1. Because the vagina is connected to the outside world, and is a channel for sex, menstruation, and fetal delivery, there is a greater chance of pathogenic infections occurring clinically. 2. Because the vagina is relatively hidden, with the bladder in front of it and the rectum behind it, there is an increased chance of pathogenic infections occurring clinically. The chances of pathogenic infection are also increased clinically. These two points determine the clinical symptoms of vaginitis in women, especially if they are married, but not 100% of married women will have vaginitis symptoms.
