1. Is it necessary for both couples to have preconception tests? What is the importance of preconception checkups? If there is no obvious disease, you should do some routine checkups, such as an ultrasound to see if there are any problems with the uterus and adnexa, while men should check the semen routine to see if they are qualified, because at present, it is especially common for men to have semen problems. Of course, the four eugenics tests are indispensable. If there is a possibility of disease, you should do some detailed examination. Special attention should be paid to those who usually have symptoms such as adnexitis, dysmenorrhea, irregular menstruation and obesity. For couples who have been in contact with infectious diseases, relevant tests should also be done, such as hepatitis immune system indicators, which should rule out the possibility of being infected; if the reproductive system has been infected, Mycoplasma solium, Chlamydia trachomatis, anti-reproductive mycoplasma, Mycoplasma humanum, etc. should be checked; if there are cases of menstrual intercourse, etc., anti-sperm antibodies should also be checked… …The content of the examination should be determined according to your health condition to prevent accidents after pregnancy. For problems detected by the test, you should actively treat them and not have children with diseases. Whenever a couple is tested for a problem, they should not be careless. There are some men who have been checked out for poor sperm quality and often do not pay attention to it, resulting in problems with the quality of fertilized eggs and miscarriages; there are also women who have fallopian tubes that are not open, often with a fluke mentality, resulting in ectopic pregnancies; there are also some who do not pay attention to their health and do not get rid of bad habits before they get pregnant, which is also very unfavorable to eugenics. 2.What are the preconception checkup items and what should I pay attention to?

If the mother is a viral hepatitis patient and not detected in time, pregnancy can result in very serious consequences, premature delivery and even death of the newborn. Hepatitis virus can also be transmitted vertically to the child. 5. Chest X-ray: diagnosis of tuberculosis and other lung diseases. Pregnancy in women with tuberculosis can limit the medication used for treatment, making treatment compromised. Moreover, active tuberculosis is often aggravated by postpartum exertion, and there is a risk of transmission to the child. 6.Gynecological endocrine complete set: diagnosis of ovarian diseases such as irregular menstruation, for example, women with ovarian tumor, even if the tumor is benign, after pregnancy often affects the observation of the tumor because of the enlargement of the uterus, and even leads to miscarriage, premature birth and other dangers. 7, routine white belt: screening for trichomonas, mold, bacterial infections, if suffering from sexually transmitted diseases, it is best to be thoroughly treated before pregnancy.
