The cost of the imaging procedure varies from place to place, and is around 500-600 RMB (please refer to the prices published by the local price bureau). The imaging is mainly applied to the fallopian tubes to find out whether the tubes are open, blocked, or possibly fluid-filled bilaterally. For women who have been preparing for pregnancy for a long time and have not been able to conceive, the test should be performed within 3-7 days after menstruation, during which intercourse is prohibited to avoid pregnancy.
