Tubal imaging is a minimally invasive test that involves placing a catheter into the uterine cavity, injecting a fluid containing a contrast medium through the catheter, and instant X-ray imaging and radiography to observe the morphology and function of the fallopian tubes, and is commonly used for infertility testing. Given the invasive nature of the test and the possible discomfort during the procedure, not all patients need to undergo the test at the time of initial consultation. It is important to choose the right time for tubal screening so as not to delay the diagnosis and to reduce the patient’s pain and financial burden. Early tubal screening is recommended in the following cases: 1. Patients who intend to become pregnant naturally more than six months after pelvic surgery, such as pelvic endometriosis, ectopic pregnancy surgery and conservative treatment, appendectomy, ovarian and uterine surgery, and after pelvic adhesion release surgery. 2. History of previous uterine operations, including abortion, diagnostic curettage, fetal abortion clearance, IUD removal/release, hysteroscopic surgery, etc. 3.Patients with infertility after cesarean section. 4.Patients who are to be treated with artificial insemination due to oligospermia or azoospermia in the male partner. 5.Patients with positive cervical canal secretion test for chlamydia, and early examination after treatment to turn negative. 6. Patients with repeated vaginitis attacks should be examined as early as possible after normal treatment. 7. Patients with suspected genital abnormalities. In the following cases, tubal imaging can be postponed after excluding the above high-risk factors: 1. Patients with simple ovulation disorder without other infertility factors. 2. Patients whose male partner’s semen status is unknown. 3. Patients with recurrent spontaneous miscarriage but undiagnosed infertility. Appropriate timing of examination and treatment is the most effective and economical way to minimize the pain of patients. The doctor should uphold the medical service principle of putting the patient first to choose the appropriate treatment plan and timing for the patient, and the patient should follow the doctor’s advice well, so that both parties can trust each other and be mutually responsible, making the infertility treatment process more rational and humanized.
