Question

Quizplus · Accepted Answer

During the fetal period, teratogens can still have an impact, particularly on parts of the body that continue to develop later in pregnancy, such as the ears. This period is less vulnerable to teratogens compared to the embryonic period, but it is incorrect to say teratogens rarely have any impact or most likely cause serious defects. Teratogenic damage leading to miscarriage is more common in the earlier stages of pregnancy.
