What exactly is fallopian tube blockage? Why does it happen?

Fallopian tube obstruction generally has no typical symptoms. The most common symptom is infertility. The fallopian tube has the function of transporting sperm, taking in eggs and fertilized eggs and sending them to the uterine cavity. Fallopian tube obstruction can hinder the passage of sperm and fertilized eggs, and can also lead to ectopic pregnancy; chronic pelvic pain and fallopian tube fluid may also occur. The most common cause of fallopian tube obstruction is pelvic inflammatory disease, which can cause endometritis after pelvic inflammatory disease infection.

The epithelial cells of the fallopian tube are destroyed, the cilia of the epithelial cells disappear, or the folds of the fallopian tube adhere, causing mechanical obstruction and blockage of the fallopian tube lumen. Inflammation can also invade the muscle layer of the fallopian tube wall, forming scar fibrosis and affecting the peristalsis of the fallopian tube, which can cause infertility and ectopic pregnancy. The clinical treatment of fallopian tube obstruction needs to be individualized according to the site, degree, age, ovarian function and male semen status of infertility. If successful, hysteroscopy combined with melantong fluid can test pregnancy for 6 months to 1 year; if pregnancy fails after 6 months to 1 year, IVF can be replaced. If the fluid fails, the baby can be directly fed. If inflammation is caused, symptoms such as abdominal pain, back pain, and sexual pain may occur next time. Patients can undergo further diagnosis through salpingography.
