How does the principle of pressure apply to intrauterine devices (IUDs)?
Intrauterine devices (IUDs) work based on the principles of pressure and mechanical interference. Once inserted into the uterus, an IUD creates a local inflammatory reaction that generates a slight increase in intrauterine pressure. This environment is hostile to sperm and prevents fertilization. The physical presence of the IUD also disrupts the normal movement and function of sperm and eggs.
