Teratogens effects on the embryo and subsequent growth and development
Any exposure that brings about harm to an unborn or breastfeeding baby is a “teratogen. Teratogens can be alcohol, illegal drugs, prescription/non-prescription medications, vaccines, illnesses, occupational exposures, environmental exposures, or maternal autoimmune disorders (Profet, 1995). Malfunctions caused by drugs are possibly preventable. A teratogen can induce or increase the incidence of a congenital malformation (Sulik, Cook and Webster, 1988).The paper aims at explaining the particular effects of the various teratogens i.e. radiations, infectious agents, drugs, maternal conditions, chemical exposures, toxic metals and thermo disruptions and the effects they have on an embryo.

In conclusion, Radiations, Infectious agents, Drugs, Thermo Disruptions, Maternal Conditions are some of the teratogens that affect the embryo. Hence, embryonic period exposure to teratogenic has the greatest likelihood of resulting in a structural anomaly. Therefore, as teratogens have the ability to affect many organ systems, the form of defects caused depends upon differentiating systems at the time of teratogenic exposure.
