Inflammatory vaginal disease can have an impact on pregnancy in two ways: First, inflammatory vaginal disease can cause upstream infection, leading to endometrial inflammatory disease and tubal inflammatory disease. If the patient conceives, it may lead to preterm abortion or embryonic arrest. Secondly, vaginal inflammatory diseases can affect the local environment of the vagina and have a sperm-killing effect on the sperm, which can reduce the quality of the sperm and affect the conception of the patient. It is best not to have intercourse and not to conceive when the patient has vaginal inflammatory disease, and to wait until the inflammation is cured before conceiving. If the patient is already pregnant and later becomes infected with vaginal inflammatory disease, the patient can continue the pregnancy, but must actively treat the inflammatory disease to avoid upstream infection.
