Abstract

Background

Reproduction in captive chimpanzees (Pan troglodytes) can be controlled by the insertion of intrauterine devices (IUDs) for females who do not reliably take oral contraceptives. Previous literature describes the use of improvised devices made from syringe cases as a speculum to accommodate the depth of the vaginal vault.

Methods

Copper IUDs (model T380A) were inserted in two sanctuary-housed chimpanzees. A disposable human small-sized vaginal speculum (Welch Allyn KleenSpec) with an illumination system provided a good view of the cervix. A 3/4 mm dilator and a uterine sound aided insertion.

Results

After multiple rounds of dilation, the uterine sound was still necessary to manipulate the IUD to the fundus of the uterus. Correct placement was confirmed by ultrasonography and radiology.

Conclusion

Inserting IUDs in chimpanzees can prove challenging. Having appropriate equipment available, such as varied sizes of speculums and dilators, is crucial. Gynecologists and ultrasonographers with experience inserting IUDs in humans can help ensure correct placement.

利用超声和放射学确定保护区黑猩猩（泛穴居人）宫内节育器的置入。

背景：圈养黑猩猩（Pan troglodytes）的生殖可以通过插入宫内节育器（iud）来控制那些不可靠地服用口服避孕药的雌性。以前的文献描述了使用由注射器盒制成的临时装置作为窥镜，以适应阴道穹窿的深度。方法：对2只收容黑猩猩置入T380A型铜宫内节育器。一个带有照明系统的一次性人类小型阴道窥镜（Welch Allyn KleenSpec）提供了宫颈的良好视图。一个3/4毫米扩张器和子宫声辅助插入。结果：经多轮扩张后，仍需借助宫腔声将宫内节育器移至子宫底。经超声及影像学检查证实放置位置正确。结论：在黑猩猩身上植入宫内节育器是具有挑战性的。有适当的设备，如不同大小的窥镜和扩张器，是至关重要的。有经验的妇科医生和超声医师可以帮助确保正确放置宫内节育器。
