  • How is pregnancy duration typically measured in weeks?
    Pregnancy is measured as approximately 40 weeks, starting from the first day of the mother's last menstrual period (LMP).
  • What is the difference between pregnancy and gestation?
    Pregnancy refers to the state of the mother, while gestation is the developmental timeline of the embryo and fetus from conception to birth.
  • Why is proper nutrition before conception important?
    Proper nutrition before conception helps prevent early nutritional deficiencies, supports healthy conception, and reduces risks like neural tube defects.
  • What is a neural tube defect and how can it be prevented?
    A neural tube defect is a birth defect of the brain or spinal cord, often prevented by adequate folate (vitamin B9) intake before and during early pregnancy.
  • Why should both men and women follow preconception nutrition strategies?
    Healthy diets and avoiding teratogens improve sperm quality in men and overall reproductive health in both sexes, increasing chances of healthy conception.
  • What are teratogens?
    Teratogens are substances that disrupt normal fetal development and can cause birth defects or miscarriage.
  • Name three examples of strictly forbidden teratogens during preconception and pregnancy.
    Recreational drugs, cigarettes, alcohol, unpasteurized soft cheeses, and high-mercury fish are strictly forbidden.

  • What is the recommended limit for caffeine intake during pregnancy?
    Caffeine should be limited to one to two cups of coffee per day.

    Vitamin A can accumulate in the body and become toxic if overconsumed.

    Low-mercury fish provide essential fatty acids important for fetal development and are safe in moderation.
  • What is the risk associated with high-mercury fish during pregnancy?
    High-mercury fish are toxic and can cause birth defects, so they should be avoided.
  • Why should herbal teas and supplements be used cautiously during pregnancy?
    They are not tightly regulated and may contain teratogens.
  • What is a spontaneous abortion and what can cause it?
    A spontaneous abortion, or miscarriage, is the unintentional loss of pregnancy before 20 weeks, often caused by teratogens.
