What tests should be done for fallopian tube patency obstruction?

Patient's question:

Got married for two years without pregnancy. The doctor said it's fallopian tube patency but not smooth. I took the medicine prescribed by the doctor, but it hasn't helped yet. I want to check what's really going on. What tests should be done for fallopian tube patency but not smooth?

Doctor's answer:

Hello, the fallopian tubes play a crucial role in transporting sperm, absorbing eggs, and delivering fertilized eggs to the uterine cavity. Fallopian tube blockage obstructs the passage of sperm and fertilized eggs, leading to miscarriage, ectopic pregnancy, or infertility. Methods for diagnosing fallopian tube blockage include:
1. Hysterosalpingography (HSG): Currently, this is one of the most widely used clinical methods. It can provide an accurate diagnosis of fallopian tube blockage, has a high accuracy rate, and also offers certain therapeutic effects. It is the most commonly used examination method to determine whether the fallopian tubes are patent, the degree of patency, and the specific location of blockage.
2. Hysteroscopy and Laparoscopy: Hysteroscopy and laparoscopy are essential examination and treatment methods for female infertility. Laparoscopic technology is a minimally invasive surgical procedure that can clearly visualize the tissues and organs in the pelvic and abdominal cavities, enabling rapid and definitive diagnosis.
