Before pregnancy, both prospective parents should promptly adjust their health status and lifestyle habits, and undergo pre-pregnancy checkups—essential preparations for conception. Below is a detailed introduction.
Pre-pregnancy Health Principles
Stop contraception 2–3 months before conception.Currently, most couples use either condoms or oral contraceptives for birth control. If you've been relying on oral contraceptives or an IUD, discontinue these methods 2–3 months before trying to conceive and allow at least one full menstrual cycle to occur. The synthetic progestin in oral contraceptives can adversely affect embryonic development.
If an unexpected pregnancy occurs during contraception, prospective parents should proactively consult a doctor. The decision to continue the pregnancy should be based on the timing of conception and the potential impact of oral contraceptives.
Couples should quit smoking and drinking alcohol 3 months in advance. Alcohol may enhance sexual desire, and many couples engage in frequent drinking.Once you decide to have a baby, it's time to say goodbye to tobacco and alcohol. This is because nicotine in cigarettes and ethanol in alcohol cause significant damage to both sperm and eggs.
It's important to note that after quitting tobacco and alcohol, it takes at least three months for the body to metabolize and eliminate nicotine and alcohol. This ensures healthy egg development for conception.
Begin folic acid supplementation three months before conception. Preconception folic acid supplementation is now a key component of China's eugenics and childbirth planning initiatives. Women undergoing preconception checkups at specialized hospitals are eligible to receive state-subsidized folic acid supplements free of charge.Folic acid is a vital nutrient for embryonic neural tube development. Deficiency in women can impair neural tube formation, leading to birth defects such as anencephaly, spina bifida, and encephalocele.
The recommendation to start folic acid supplementation three months before conception stems from the fact that it takes approximately four weeks for the body to correct folate deficiency after beginning supplementation.Only then can the baby have sufficient folic acid during the critical neural tube formation period in early pregnancy.
Reduce caffeine intake. For working women, coffee serves not only as a bourgeois indulgence but also as a vital tool for coping with intense pressure. Many women even find it difficult to work effectively without coffee. However, for women preparing for pregnancy, caffeine is not beneficial.Studies show women who drink at least 5 cups of coffee daily have a 50% lower chance of conception, while those consuming fewer than 5 cups per day do not experience this "side effect."
Therefore, experts advise women trying to conceive to limit daily caffeine intake to under 200 milligrams (less than 2 cups) to better ensure conception opportunities.
Exercise caution with medications before and after pregnancy.Some women mistakenly believe that while pregnancy requires avoiding all medications, preconception use is harmless. This is not true—certain drugs taken before conception can expose the developing baby to various adverse effects. We know pregnancy is typically detected only after 4–5 weeks. Therefore, women entering the preconception phase should minimize medication use, especially antibiotics or cold remedies.If medication is necessary, inform your doctor of your pregnancy plans before obtaining a prescription. This applies not only to women but also to husbands, as certain medications may damage sperm. Couples should exercise regularly together. A healthy body is essential for successful conception. Appropriate pre-pregnancy exercise can help prospective parents improve their chances of conceiving!Women with uterine coldness can improve their uterine environment through exercise, helping the baby settle in faster. Generally, those with lower strength and endurance but greater flexibility and agility should choose aerobics, swimming, or jogging. Men should avoid overly strenuous exercise to prevent high temperatures from damaging sperm vitality. Swimming, running, and ball sports are all good choices.Regardless of the exercise method chosen, progress should be gradual and consistent to genuinely enhance physical fitness.
For optimal prenatal care, preconception checkups are also essential.
Preconception Screening Items
Complete Blood Count (Blood Type): Early detection of anemia and other hematological disorders.
Hepatitis Testing and Liver Damage Assessment: Timely prevention of vertical transmission of hepatitis viruses to the child.
"Four Toxins" Screening: Antibody testing for rubella virus, cytomegalovirus, toxoplasma, and herpes simplex virus.
HIV: If infected, HIV can be transmitted to the child through the placenta, birth canal during delivery, or via breast milk after birth.
Syphilis Serology: Syphilis can infect partners, causing miscarriage, premature birth, stillbirth, or congenital syphilis in offspring. However, it is completely curable with early detection and treatment.
Urinalysis: Aids in the early detection or diagnosis of kidney disorders.
Chromosome Testing: Both partners should undergo testing to assess egg or sperm abnormalities, enabling early detection of genetic disorders like Klinefelter syndrome, Turner syndrome, and infertility.
Blood Type Testing: Determines compatibility between partners' blood types to prevent complications in the infant, such as hemolytic disease, miscarriage, stillbirth, or birth defects.
Chest X-ray: Primarily used to diagnose pulmonary diseases like tuberculosis.
Echocardiogram: Assesses heart function. Abnormal heart function can impair blood circulation, affecting fetal blood supply and leading to miscarriage or premature birth, while also threatening the mother's health and life.
Breast examination: Identifies conditions like breast hyperplasia or fibroadenomas. Early intervention ensures readiness for breastfeeding.
Expectant parents seeking optimal prenatal care should prioritize these steps.
