Gynecological diseases will affect pregnancy. When a woman suffers from gynecological diseases, it will obviously reduce her chances of conceiving, and common gynecological diseases include vaginitis, cervicitis, cervical cancer, cervical erosion, endometritis, endometrial cancer, pelvic inflammatory disease, salpingitis, ovarian inflammation, and so on, and among them, salpingitis is the most common cause of infertility. When a woman suffers from tubalitis, it is easy to lead to ovulation disorder or ectopic pregnancy. When a woman suffers from cervicitis or cervical erosion, it will affect the smooth entry of fertilized egg into the uterine cavity, thus affecting pregnancy. If a woman suffers from endometritis or endometrial cancer, it will affect the successful implantation of the fertilized egg and reduce the chances of conception. When a woman suffers from ovarian infections, the eggs are not able to develop well, and thus no mature eggs are released, which may lead to infertility. Gynecological diseases pose a serious threat to women’s health and affect normal pregnancy, but mild gynecological inflammation does not affect pregnancy, such as mild cervical erosion, asymptomatic pelvic inflammatory disease, mild vaginitis and so on.
