The fallopian tubes are an important component of the female reproductive system and play a crucial role in the process of pregnancy. First, the fallopian tubes are the site where sperm and eggs meet to form a fertilized egg. Second, after the fertilized egg is formed, the fallopian tubes are responsible for transporting it to the uterine cavity. Therefore, when any of these two processes encounter issues, it might result in infertility or an ectopic pregnancy. Therefore, inflammation of the fallopian tubes can indeed cause infertility. When significant inflammation of the fallopian tubes occurs, it affects their function, causing them to fail in transporting eggs. Under such circumstances, the sperm and egg cannot meet inside the fallopian tubes for fertilization, resulting in infertility. Additionally, even if a fertilized egg is formed, the fallopian tubes may fail to transport it to the uterine cavity, sometimes causing an ectopic pregnancy.
