Teratogenetic Termination Period

Teratogenetic termination period (TTP) is the time period during which the fetus is exposed to adverse factors that can lead to the development of birth defects and other pathologies. During this period, the fetus is extremely susceptible to any harmful effects, including teratogenic factors such as alcohol, drug use, smoking, infectious diseases and others.

The cause of TTP is the process of embryogenesis, during which active processes of formation of organs and systems of the fetus occur. They can be disrupted due to the negative influence of external or internal negative factors. For example, drinking alcohol or taking medications can have a negative impact on the development of the fetal nervous system, which can subsequently lead to disruption of its functioning. Another example is smoking, which can impair the development of the fetal pulmonary system and
