After the first sterilization surgery, if a woman has a request for pregnancy, it is recommended that the patient prepare for pregnancy after 3-6 months of sterilization. This is because the endometrium and ovarian function of the patient will be affected to some extent after the procedure, and the patient will need a recovery process. Usually about 3 months will be able to return to normal, so the patient can prepare for pregnancy. If the patient has been preparing for pregnancy for more than 1 year without pregnancy, it should be considered that the patient may have endometrial damage or inflammation of the fallopian tubes, tubal impassability. In this case, the patient should focus on screening the uterine cavity and screening the fallopian tubes. The patient may have a hysteroscopy, along with a hysteroscopic fluid pass or a tubalogram. If the patient has problems with the uterine cavity or the fallopian tubes, then the patient needs to be treated promptly as appropriate.
