Patient's question:
What should I do if I get pregnant unexpectedly? The harm is relatively small. What are the principles of intrauterine devices (IUDs)?Doctor's answer:
An intrauterine device (IUD) is placed inside the uterine cavity of a woman of childbearing age. It achieves the purpose of induced abortion and contraception through mechanical stimulation and interference from chemical substances, without inhibiting ovulation or affecting the female endocrine system. As a result, it avoids the adverse reactions commonly associated with drug-based contraception.After years of practical improvement, the intrauterine devices currently used in clinical practice are mostly copper-containing or drug-releasing IUDs. The supporting materials include plastics, polyethylene, memory alloys, and others. Their shapes are not uniform, including round, T-shaped, V-shaped, Y-shaped, and chain-like forms. Different materials and shapes of IUDs have their own characteristics, making them suitable for women with varying physiques and needs.
