Infection with Gardnerella is not a lifelong ban on sexual intercourse. The infection needs to be controlled before having sex, and it is not advisable to have sex before the infection is under control. Gardnerella is an anaerobic bacterium. Under normal circumstances, a certain amount of Gardnerella exists in a woman’s vagina and plays a role in maintaining a stable vaginal environment. However, if a woman has sex frequently, has multiple sexual partners, or overdo vaginal douching, the balance of the vaginal environment will be disturbed, resulting in a decrease in the number of Lactobacillus bacteria in the vagina and an overpopulation of Gardnerella, which will lead to Gardnerella vaginitis. However, Gardnerella infection does not mean that you can’t have sex for the rest of your life. Gardnerella vaginitis can be cured by active treatment (commonly used anti-anaerobic drugs, such as metronidazole, tinidazole, etc.), and patients can continue to have sex after the cure, and need to pay attention to strengthening sexual hygiene. However, sexual intercourse should be suspended during the treatment period in order to control the infection as soon as possible.
