After general surgery, we will routinely advise patients not to have sex for two weeks after surgery. In order to check the effect of fallopian tube recanalization, patients will be advised to have fallopian tube drainage operation 3 ~ 7 days after the next menstruation to check whether the fallopian tube is unobstructed and prevent the fallopian tube from adhering again. If the test results are normal at this time, the patient can prepare for pregnancy. In order to make the body recover the most thoroughly, you can also formally prepare for pregnancy three months after surgery. However, after tubal recanalization, the operation effect is the best within half a year, and it may be adhered again after half a year. Therefore, it is suggested that patients who have undergone fallopian tube recanalization surgery should actively prepare for pregnancy within three months after surgery, preferably within half a year.
