Marriage tests have also become a new item in the battle of wits between couples, trying to see the clues from the medical reports. In fact, the marriage test is not to figure out his black history or to find out her past, the marriage test is for a healthier life for the couple. But the fact is that the marriage test can only find out the history of pregnancy, not whether or not sex has been performed, and those additional hymen-related tests are not used as criteria to determine whether or not sex has been performed. During the marriage test, the doctor will ask both parties about their situation before the test, the most critical of which include the following: 1. whether there is anyone in the family, especially in the immediate family, who has a genetic predisposition to diseases such as mental illness, dementia, thalassemia, congenital malformations, etc. 2. whether one has previously suffered from any genitourinary-related diseases and, if so, how they were treated. In addition to these, the doctor will need to know the personal life history of both partners, including recent work and residential life, smoking and alcohol habits, the woman’s menstrual history, and the man’s history of seminal emission. For those who remarry, the doctor also needs to ask about the past marital history. As for some private issues: whether the woman has a history of childbirth, whether both parties have had certain diseases, the doctor asked only for the need to analyze the disease, will be absolutely confidential, without the permission of the person concerned, is not able to tell anyone, including the other party in the marriage. The marriage test can detect that the woman has had sex, but it is usually not marked on the marriage test report. The results of the test are not usually told to the man. Before the test, you should fast and keep an empty stomach. You should have a good diet and habits of living and working. Marriage test is not a “demon mirror” before marriage, but only to enable everyone to better and healthier into marriage. References: [1] Jiang Zhijun.
