The marriage examination needs to check the internal and external genitalia, and will check the internal vagina, but the specific situation varies from person to person. Marital examination for both internal and external genital tract will conduct a preliminary checkup, through the routine gynecological internal examination to observe whether there are reproductive tract deformities or abnormalities such as vaginal diaphragm, vaginal septum, congenital absence of vagina, etc., to be able to carry out a preliminary judgment on the reproductive function of women. At the same time, leukorrhea routine, gynecological ultrasound, cervical screening and other tests will be conducted to initially determine whether there are gynecological inflammation, ovarian cysts, uterine abnormalities, and so on. If you do not have sex before the marriage test, you will only observe the vulva and gynecological ultrasound, not gynecological internal examination, cervical screening and other tests. There are also some routine programs, such as liver and kidney function, electrocardiogram, infectious diseases, blood routine, etc., which can assess the general condition of the body.
