Some gynecological inflammatory diseases will affect pregnancy and some will not. For example, vulvovaginal dermatitis is clinically normal for the vast majority of pregnancies. However, if the local inflammation of the vagina is serious or the inflammation of the cervix is serious, it will secrete a large number of white blood cells, which have the function of phagocytosis of sperm, so it will lead to infertility, but after active treatment of the inflammation there is still a clinical possibility of pregnancy. If pelvic inflammatory disease is not treated in a timely manner, localized obstruction of the fallopian tubes will result, and sperm and eggs will not be able to combine, which will also cause infertility. In case of chronic pelvic inflammatory disease, if the inflammation affects the ovaries, the normal function of the ovaries is affected locally and the local cells of the ovaries are destroyed, which can also lead to infertility clinically.
