The cost of a premarital examination is about 500 RMB. Usually, the premarital examination is about the basic health condition of both men and women, as well as the absence of serious hereditary diseases and mental diseases, and the absence of abnormal development of reproductive organs. Usually the general checkups include routine blood, blood sugar, blood lipids, liver function, kidney function, electrocardiogram and radiological examination of the chest. The most important tests are family genetic disorders and the examination of male and female reproductive organs, such as the presence of varicocele or congenital testicular dysplasia in men and congenital absence of uterus or vaginal atresia in women.
