Marriage test may not necessarily detect a history of abortion, but if the lining of the uterus is damaged after an abortion, it can be detected through professional gynecological ultrasound and other means. Generally, there are drug abortion and artificial abortion. Drug abortion refers to the oral termination of early pregnancy with mifepristone plus misoprostol, while artificial abortion refers to the termination of pregnancy by artificial means due to unwanted pregnancy, disease and other reasons. Common tests for the female partner in a marriage examination include tests of the ovaries, fallopian tubes, and uterus. If a simple abortion does not leave any after-effects, it will not be detected in the marriage examination because the uterine lining has a self-repairing function. However, if the damage to the uterine lining causes adhesions in the uterine cavity, it may cause infertility symptoms, which can be detected by the marriage test.
