Tubal fluids refer to tubal fluids, and women are usually not recommended to get pregnant in the month of tubal fluids, and are recommended to get pregnant after 3 months. Tubal fluids are used to check the patency of the fallopian tubes, as well as to treat mild tubal blockage. Since the accuracy of the test is not very high, it has been replaced by hysterosalpingography or combined hysterolaparoscopy. Tubal fluids are injected into the uterine cavity through a catheter, and judging whether the fallopian tubes are open or not is subjective according to the amount of resistance to the injection, the amount of fluid injected, and the patient’s feeling, etc. Some female patients are suffering from mild tubal blockage due to the fact that their tubes are not open. Some female patients undergo the fluid test because of mild tubal blockage, and pregnancy is usually not recommended in the same month because of the possibility of ectopic pregnancy. When the fallopian tubes are open but not smooth, it is not advisable to use tubal fluids multiple times for treatment, as fluids have a certain degree of damage to the fallopian tubes, which will reduce the peristaltic function of the tubes and thus increase the possibility of ectopic pregnancy. Tubal fluids are usually checked in 3-7 days after the menstrual period is clean, after the menstrual period is clean until the examination can not be coitus. 2 weeks prohibit sexual intercourse and pelvic baths, antibiotics can be applied as appropriate to prevent infection.
