Tubal imaging is an invasive test, which may cause upstream infection and lead to adhesions in the fallopian tubes or pelvic inflammatory disease, and there is also radioactive damage in tubal imaging, so it is not advisable to do it for a second time at least three months apart. The significance of having a tubal imaging within a short period of time is not very great. If no relevant treatment is given after the tubal imaging, the degree of tubal patency will not change much within six months, so the patient should prepare for pregnancy after having a tubal examination indicating normal tubal patency. If the patient cannot conceive after more than half a year, it is not necessary to perform tubal examination, and other tests are needed to determine whether there are other reasons for the inability to conceive, such as hysteroscopy to determine the endometrium and sex hormone six tests to determine the ovarian function and ovulation function of the patient.
