1. Do not have intercourse after menstruation, see the clinic after menstruation (Shanghai patients) or on the 2nd-3rd day after menstruation (foreign patients can reduce the number of trips to and from Shanghai), and have the white belt routine tested (the results can be seen immediately), after normal, you can open an application form to make an appointment for tubal intervention (also often abbreviated as: SSG, intubation, guidewire recanalization, etc., which are the same thing) 2. (before ovulation) on the 3rd-7th day after menstruation. The SSG procedure usually takes about 15 minutes and is not very painful if the procedure goes smoothly, so it is tolerable. 4. Precautions after SSG: (1) No intercourse and no tub bathing for 2 weeks after the procedure; (2) Take oral antibiotics for 3-5 days; (3) Pick up the report from Outpatient Room 104 (Huangpu Campus) / Outpatient Lobby Desk (Yangpu Campus) after 2 working days. If you need interventional film, you need to pick up the report and pay 20 RMB at the outpatient clinic and then pick up the film at the radiology department. (4) Both hospitals are connected by PACS, so you can pick up reports and films from each other (warm tip: you don’t need to go to the other hospital to pick up reports or films in order to see an outpatient, so as to reduce unnecessary travel). (5) The fastest – you can try to conceive in the next menstrual cycle after tubal ligation. (6) If you find that you are successful in trying to conceive (trying to conceive during ovulation increases the success rate of conception), go to the hospital as early as possible to check to rule out ectopic pregnancy. In case of ectopic pregnancy, the earlier it is found, the better the treatment effect will be and minimize the impact of ectopic pregnancy on the fallopian tubes. (7) Successful tubal unblocking is only one part of successful pregnancy. If there are irregular menstruation, poor ovulation, endocrine problems, poor sperm quality or other problems, you need to see the appropriate gynecological clinic or endocrine clinic, etc.
