Why is it necessary to open the fallopian tubes for successful conception? ”The fallopian tube is a very important passage in the normal fertility process. First, the egg and the sperm have to run like a cowherd and a weaver to meet at the magpie bridge of the fallopian tube, then they hug each other tightly in order to never be separated again and successfully merge to become a fertilized egg, and finally this fertilized egg has to run through the fallopian tube, the only way to the warm home of the uterus.” If the fallopian tubes are blocked or not open, two results can occur. One is a complete blockage of the fallopian tube, preventing the egg and sperm from meeting and resulting in infertility. The other is a blocked fallopian tube, where the sperm and egg meet and merge through many hurdles, but the fertilized egg encounters an insurmountable roadblock on its way home and has to settle in the fallopian tube, resulting in a dangerous ectopic pregnancy. According to a survey, 1/3 of the common factors for female infertility are blocked or incompetent fallopian tubes, 1/3 are ovulation disorders, and 1/3 are other problems with the uterus, vagina, and endocrine system. Therefore, for infertility patients, clinicians will ask them to have a tubal evaluation. Pre-conception tubal evaluation can increase the success rate of conception There are so many ways to address tubal problems in the clinic. One is tubal lavage, where saline is infused into the fallopian tubes, and if it doesn’t go in, it means it is blocked. This method is often performed without monitoring and is based on the doctor’s experience. There is also the iodine oil imaging carried out by the radiology department, but the patient has to take a certain amount of radiation and it takes 3 months afterwards to try to conceive. If these two methods do not work, then laparoscopic surgery is required to open up the pregnancy or assisted reproduction techniques. However, these methods can be harmful to the body. On the other hand, real-time 3D ultrasonography can be done to evaluate the patency of the tubes without the risk of radiation, and on the other hand, it can be done to open the tubes of those who are not open. The test may be slightly painful or uncomfortable, but 80% of the patients can tolerate it. In addition, there is no radiation, and you can try to conceive the next month after the test, so many patients are happy to accept it. Especially after the liberalization of the second child alone, many eligible women are already older, so they cannot afford to wait until they try to conceive for a year and then come back to find out the reason.
