Research progress on the correlation between gestational vaginal microecology and vaginal infectious diseases

The health status of the vaginal microenvironment, a complicated system, is an important indicator of female reproductive health. The vaginal flora is in a state of balance, and the microorganisms coexist and are interdependent to maintain the vaginal micro-ecological balance, which is a kind of dynamic balance influenced by endogenous and exogenous factors. Vaginal infections are traditionally treated by killing microbes in the vagina. Given the extensive study of the internal vaginal environment, people become gradually aware of the significance of maintaining the vaginal micro-ecological balance rather than blindly using antimicrobial agents. The balance in the vaginal internal environment is disrupted during the gestation period as the secretion of progesterone increases. The imbalanced vaginal micro-ecological environment may lead to vaginal infectious diseases. This paper provides a review of the relationship between the vaginal microecology and infectious diseases during gestation period.
