Tubal imaging is one of the best ways to check for blockages in the fallopian tubes at this stage. The cost of the test depends a lot on the level of the hospital, the city and the contrast agent used. The cost is not easy to assess as it includes the cost of anesthesia, as appropriate local anesthesia is sometimes applied during the tubal imaging. Usually it is around 1000 RMB. There are more causes of tubal blockage, such as severe inflammatory infections that can cause tubal blockage in many cases, such as severe inflammatory infections and congenital developmental malformations of the fallopian tubes. During the ultrasound follicle monitoring, if the follicle development is normal and ovulation is normal but you have not been pregnant, then you should be highly alert to the tubal blockage. The time to do tubal imaging should be within 3 to 7 days after the woman’s menstruation is completely clean, as the endometrium is thinner during this period, which will give better clarity during the examination and will not cause heavy bleeding. Although there may be a little pain during the test, it is very diagnostic to confirm the cause of infertility.
