If a woman has never been pregnant, the chance of having tubal blockage is small. A small number of women will have tubal adhesion and blockage, mainly because women do not pay attention to menstrual hygiene during menstruation, or have had vaginal inflammation or cervical inflammation caused by incomplete treatment of upstream infection, resulting in chronic tubal inflammation, and women will cause tubal adhesion and blockage. When a woman has a general health checkup during her pregnancy preparation period, if she suspects a blocked fallopian tube, she can have a tubal lavage or tubal imaging to clarify the patency of the fallopian tubes. If there is a blockage of the fallopian tubes, it should be treated promptly. Otherwise, if a woman has a blockage of the fallopian tubes, she may not be able to get pregnant easily, and even if she does get pregnant, it may increase the chance of ectopic pregnancy.
