Partial patency of the fallopian tube is clinically known as tubal patency, which means that the fallopian tube is open, but when doing tubal imaging, there is more resistance when hitting the contrast agent, and the contrast agent does not pass smoothly. Tubal patency test is commonly used in patients with infertility and recurrent miscarriages, etc., and patients are instructed to prepare for pregnancy based on the results. It is possible for sperm and egg to meet naturally after sex in patients with tubal patency, and there is also the possibility of natural conception. If the doctor determines that the patient can try to conceive naturally, he or she can try to conceive naturally first. If the tubal opacity is caused by inflammation, fluid buildup, etc., it can be treated under the doctor’s guidance. If the doctor judges that the patient’s chances of conceiving naturally are low, he or she may recommend IVF.
