Answer:
teratogenic?
After the fertilization of the egg (conception), it can take six to nine days for the implantation of the fertilized egg to occur in the uterus. Once the fertilized egg enters the uterus, the blood supply between the mother and the embryo is established. In other words, if there is something in the mother's blood, it can now pass to the developing fetus. Teratogens are thought to affect the fetus approximately 10 to 14 days after conception.
During a baby's development, certain organs form at certain times. If a teratogen has the ability to interfere with the closure of the neural tube, for example, exposure must occur between the middle of week 3 and the middle of week 4 of pregnancy, since it is from that moment that the tube neural begins to close in the fetus. Some organ systems are sensitive to teratogens throughout pregnancy, such as the baby's central nervous system, which includes the brain and spine. One of the teratogens that affects the central nervous system is alcohol, which, at any time during pregnancy, can cause birth defects and health problems in the baby, since the central nervous system is sensitive to teratogens during the nine months of pregnancy . This is the reason why alcohol consumption should be completely avoided during pregnancy.
