If the ectopic pregnancy removed one side of the fallopian tube, then only the other side of the fallopian tube is left, you can make a comprehensive judgment based on the ovarian function, decide when to do tubalography. If the ovarian function is good, you can try to get pregnant for another six months after the ectopic pregnancy surgery. If you still can’t get pregnant, you can consider having a tubalogram to check if the other side of the tube is open. If the other side of the fallopian tube is open, follicle monitoring can be done, and coitus can be instructed when the same side of the ovary is ovulating, or artificial insemination can be performed when the same side of the ovary is ovulating. If the other fallopian tube is not open or is obstructed, it is recommended to consider IVF for fertility treatment.
