1. There is no need for premarital examination before getting a marriage certificate. The new marriage law stipulates that voluntary premarital examination is now required. But premarital examination is of great benefit to ensure happiness after marriage. Premarital examination refers to the routine physical examination and genital examination of both sexes before marriage, with the purpose of finding diseases, intervening some diseases at an early stage and taking active preventive measures to "escort" healthy babies in the future. The advantage of premarital examination is that it is beneficial to the health of both parties and the next generation. Through the comprehensive physical examination before marriage, abnormal conditions and diseases are found, and early diagnosis and active correction are realized. For example, diseases found in physical examination that have a temporary or permanent impact on marriage or childbirth can be completed under the guidance of a doctor. Both sides and the next generation are healthy in decision-making and arrangement.
2. The autonomy of premarital examination is conducive to actively and effectively mastering the timing of pregnancy and contraceptive methods. Doctors choose the best method of pregnancy or contraception for them according to their own health, physical condition and birth plan, and guide them to take effective measures and master science and technology. For those who require a natural delivery, it can help them improve the success rate of planned pregnancy. The preparation of contraceptives can reduce unintended pregnancy and abortion and provide protection for the health of women and children.
3. Conducive to prenatal and postnatal care and improve the quality of the people. Through family history investigation, pedigree investigation and pedigree analysis, combined with premarital examination, doctors can make a clear diagnosis of some genetic defects, and calculate the risk level of "affecting the next generation of eugenics" according to their transmission rules to help get married. Both parties make marriage and childbearing decisions to reduce or avoid inappropriate childbearing caused by marriage and genetic diseases.
