Morphological characteristics of incrustates of intrauterine contraceptive devices.
The morphology of incrustates formed on intrauterine contraceptive devices (IUD) is described. It is demonstrated that due to manufacturing technology some IUDs have long, parallel excavations serving as sites for incrustate formation. A regional difference of incrustation on the different parts of IUD has also been observed. Electron microscopy was carried out in tissue fragments attached to removed IUDs. Alterations correspond to acute or chronic inflammation. Incrustate on the surface of IUD appears to have a primary role in induction of the process.
