To check whether the fallopian tube is blocked or not, tubal imaging, laparoscopic tubal methylene blue fluid and other tests can be performed. 1. Tubal imaging: Tubal imaging is an examination technique that injects contrast material into the fallopian tube to show the shape of the tube and to determine whether the tube is open or not. Generally speaking, the fallopian tube is the organ that transports eggs, sperms and fertilized eggs, which is very important when a woman is pregnant. 2. Laparoscopic tubal methylene blue solution: When the fallopian tube is blocked, methylene blue solution can be injected into the uterus, and then laparoscopy can be used to observe whether the fallopian tube is open or not. If the existence of tubal blockage is considered in daily life, it is recommended to go to a regular hospital to avoid delay.
