The possible injurious effects of abdominal intrauterine devices (IUDs), including Cu-IUDs, inert IUDs, and "closed' IUDs, were evaluated in an experimental study. Pigs and dogs were used as they have, respectively, a propensity to form adhesions and a pronounced tendency to develop serious peritonitis. The reactions expected in humans might be intermediate to those found in these two kinds of experimental animals. The results of this study indicate that an inert or copper-bearing IUD usually remains in its initial position in the abdominal cavity, encapsulated by adhesions. The risk of strangulation of the intestine by a "closed' IUD seems minimal.
在一项实验研究中，对包括铜宫内节育器（IUD）、惰性IUD和“封闭式”IUD在内的腹腔内IUD可能的有害影响进行了评估。选用猪和狗作为实验对象，因为它们分别有形成粘连的倾向和发生严重腹膜炎的明显趋势。人类预期的反应可能介于这两种实验动物所观察到的反应之间。这项研究的结果表明，惰性或含铜IUD通常会留在腹腔的初始位置，被粘连组织包裹。“封闭式”IUD导致肠道绞窄的风险似乎极小。
