Where is the best place to treat infertility?

Patient's question:

46 years old, no children, history of miscarriage, unable to conceive, 80% blockage of the left fallopian tube

Doctor's answer:

The causes of fallopian tube blockage are multiple. Most fallopian tube blockages are caused by inflammation, such as pelvic inflammatory disease, which is a very common condition. If the inflammation spreads to the fallopian tubes, it can lead to fallopian tube blockage in women.
Recommendation: The best treatment for fallopian tube blockage is fallopian tube intervention and recanalization. There is no effective treatment for ampullary obstruction of the fallopian tube; in vitro fertilization (IVF) can be considered. For fimbrial blockage, fimbrial ostomy can be performed, including laparoscopic ostomy and open ostomy.
