Can fallopian tube obstruction lead to biochemical pregnancy

If the fallopian tube is blocked, the probability of pregnancy is very small, and biochemical pregnancy indicates that the fallopian tube is unobstructed, but it cannot be ruled out that one side of the fallopian tube is blocked and the other side is unobstructed. Therefore, when there is any abnormal situation, active treatment should be taken to maintain a good attitude and develop good living habits.
