In brief: They usually don't
Teratogens (from terata or monstrosity) are agents that act on the developing embryo/fetus to cause birth defects.
Known mechanisms include interference with molecules that govern limb, brain, heart formation like thalidomide or Methotrexate (a folate (folic acid) inhibitor). Teratogens usually affect only the exposed pregnancy and do not change the genes of mother/fetus for future pregnancies.
