Fetotoxic

Fetotoxic refers to a substance or condition that can cause harm to a developing fetus. This harm can manifest in various ways, including birth defects, developmental delays, or even fetal death. Fetotoxic agents can be chemical, physical, or biological. Examples of chemical agents include certain medications, alcohol, illicit drugs, and environmental toxins like lead or mercury. Physical agents could include radiation. Biological agents might include certain infections.

The effects of a fetotoxic agent depend on several factors, including the specific agent, the dose or level of exposure, the duration of exposure, and the stage of fetal development at the time of exposure. The first trimester is often a critical period for organ development, making the fetus particularly vulnerable to teratogenic effects, which are structural abnormalities. However, exposure at later stages can still impact growth and neurological development.

Preventing fetotoxic exposure is crucial for a healthy pregnancy. This often involves pregnant individuals avoiding known harmful substances, consulting healthcare providers about medication safety, and minimizing exposure to environmental hazards. Many fetotoxic substances can be passed from the mother to the fetus through the placenta. Understanding and identifying these risks are key components of prenatal care.
