With the full opening of the two-child policy, more and more sisters are joining the army to prepare for pregnancy. In the sense of eugenics, if you don’t do your homework before preparing for pregnancy, you won’t be able to try to conceive properly. So, how to prepare for pregnancy? What tests are needed? Are you already confused by the various claims on the Internet? Q: Do I need to take folic acid when preparing for pregnancy? A: Ofcourse, folic acid is a vitamin B complex, which is very effective in preventing fetal neural tube development defects, anencephaly, cleft lip and palate and premature birth. In the first trimester of pregnancy, the neural tube of the fetus begins to develop. If folic acid is deficient at this stage, it will lead to fetal malformation caused by neural tube underdevelopment. If folic acid is supplemented, the occurrence of such malformations will be greatly reduced. Therefore, folic acid supplementation is very necessary. Q: When should I start taking folic acid? Are there any side effects if I take it for a long time? A: You can start 3 months before you plan to get pregnant. Take it for another three months in early pregnancy; in the middle and late pregnancy, you can continue to take it appropriately under the guidance of your doctor. Because folic acid is a water-soluble vitamin, it does not accumulate in the body and does not cause side effects when taken in small doses, and folic acid needs to be taken for a period of time to reach a constant level in the body, which is conducive to the growth and development of the fetus. Therefore, there is no need to worry about “poisoning” at all. Q: What tests should be done before preparing for pregnancy for optimal fertility? A: Don’t worry, listen to the details ~ ~ For the health of the fetus and the pregnant woman, the couple preparing for pregnancy must undergo pre-conception checkups, which are usually scheduled 3 to 6 months before preparing for pregnancy, so that when abnormalities or problems unsuitable for pregnancy are detected, timely treatment and correction can be carried out. The preconception checkup for women mainly includes blood routine, urine routine, liver and kidney function, infectious disease screening (hepatitis B, hepatitis C, AIDS, syphilis), pelvic ultrasound, TORCH (cytomegalovirus, toxoplasmosis, rubella virus, herpes simplex virus), thyroid function test, gynecological examination (including white belt routine, cervical cancer screening), etc. The male preconception examination mainly includes semen examination, infectious disease screening (hepatitis B, hepatitis C, AIDS, syphilis), etc. PS: The above items do not need to be done again if they have been checked in the routine medical examination within one year. Q：What are the precautions for preconception checkups? A：Cough~Cough~, it is really necessary to understand this, otherwise it is a waste of a trip. The following precautions: 1, women in the day of the pre-conception test fasting, because the liver and kidney function needs to be checked on an empty stomach, otherwise it will affect the normal pre-conception test. 2. Avoid the menstrual period and choose 3 to 7 days after menstruation. Don’t have sex within 3 days of the preconception test, don’t wash your vagina the day before the test and don’t use vaginal medication. The former can be performed without holding urine and is suitable for women who have sex; the latter needs to hold urine and is suitable for women who do not have sex or do not want to be examined vaginally. 4, male friends should quit smoking and drinking within three months or even six months before planning to get pregnant, because smoking can trigger sexual dysfunction, reduce fertility, affect the success rate of conception, and affect the quality of fertilized eggs and embryos; long-term heavy drinking can lead to a decrease in the number of male sperm, reduced vitality, and deformed sperm, affecting conception and embryo development. 5. Semen examination requires 2-7 days of abstinence (do not have sex for 2-7 days before the examination) for better.
