BACKGROUND
Studies on reproductive morphology are important to understand the reproductive cycle of non-human primates.
METHODS
This study describes the functional morphology of the adult female tubular genital organs in 41 Aotus (12.8 ± 6.8 years old, ranging from 3 to 25 years), with respect to reproductive status and number of parturitions.
RESULTS
In females with developing embryos, endometrial glands showed a higher secretion than other females, and the embryo implantation occupied this secretive endometrium. Changes in the thickening, number of layers, and keratinization in the vaginal epithelium suggest that vaginal cytology may be an indicator of the estrous cycle. Non-pregnant multiparous females had a larger uterine body than nulliparous females. Number of parturitions and reproductive state had an impact on tubular genital organs in female owl monkeys.
CONCLUSIONS
These results can be useful for the development of biotechnologies of reproduction and for improvement of the management of this species.
背景
生殖形态学研究对于理解非人灵长类动物的生殖周期很重要。
方法
本研究描述了41只夜猴（年龄12.8±6.8岁，范围为3至25岁）成年雌性管状生殖器官的功能形态，涉及生殖状态和分娩次数。
结果
在有发育中胚胎的雌性中，子宫内膜腺的分泌比其他雌性更高，且胚胎着床占据了这种分泌性的子宫内膜。阴道上皮增厚、层数和角化的变化表明，阴道细胞学可能是发情周期的一个指标。经产未孕雌性的子宫体比未孕雌性的更大。分娩次数和生殖状态对雌性夜猴的管状生殖器官有影响。
结论
这些结果可有助于生殖生物技术的发展以及该物种管理的改善。
