Before pregnancy preparation, women need to register for gynecological examination and men need to register for male examination. If gynecological inflammation is not treated in time, there is a possibility that the symptoms will worsen after pregnancy, and it is not convenient to treat the medication during pregnancy. Therefore, it is necessary to treat gynecological inflammation before pregnancy. In addition, it is necessary to check for endocrine and uterine development abnormalities during pregnancy preparation, which can be confirmed by ultrasound and the six endocrine tests, all of which need to be performed in the gynecology department. If the hospital has a mixed gynecology and obstetrics department, you can go directly to the obstetrics and gynecology department. If the hospital has an eugenics department, you will also need to go to the eugenics department during the pregnancy preparation period.
