Patient's question:
NoDoctor's answer:
Common teratogenic factors include microorganisms (such as viruses), drugs, and certain chemical agents, as well as certain metals and radioactive substances, among others. Data indicate that among teratogenic factors, drugs account for approximately 1.5%, physical and chemical substances for 1%, viruses and pregnancy-related diseases for 1–3%, and those whose causes remain unclear for 65%. It is noteworthy that about 20% of teratogenic factors originate from genetic diseases in parents rather than teratogenic factors from the external environment. Before the next pregnancy, proper pre-pregnancy preparation should be done.
