影响宫内节育器性能的因素：综述与建议

J Reprod Med. 1978 Sep;21(3):137-45.

IUD design features that affect performance are reviewed and discussed. The use of a medicated device designed to be placed, retained and stabilized exclusively in the frontal plane of the upper uterine segment fulfills theoretical conditions of optimum performance.

对影响宫内节育器（IUD）性能的设计特点进行了回顾和讨论。使用一种专门设计用于放置、固定并稳定在上段子宫前位平面的含药装置，满足了最佳性能的理论条件。
